Those in 1 Tim.1:19-20 had left Christ but were not eternally lost. In fact God was seeking to save them:
19
holding on to faith and a good conscience, which some have rejected and thereby shipwrecked their faith. 20Among them are Hymenaeus and Alexander, whom I have handed over to Satan to be taught not to blaspheme
As for Heb.10:26, you misinterpret it:
No more sacrifice for sins applies to those forgiven as well:
Heb.10:18 Now where there is forgiveness of these things, there is no longer any offering for sin. (NASB)
Heb.10:18 But where there [is] remission of these, [there is] no longer a sacrifice for sin. (DBY)
Heb.10:18 and where forgiveness of these is, there is no more offering for sin. (YLT)
The meaning is not that if they sin they can't be forgiven. They can (1 Jn.1:9). The same applies to those of v.26. So your argument is a failure.
The meaning of no more sacrifice for sin is that Christ's sacrifice ended all sacrifices for sin. There are no more. There will be no more.
His sacrifice is sufficient to take away everyone's sins & that is exactly what it will do:
John 1:29 The next day John saw Jesus coming toward him and said, “Look, the Lamb of God, who takes away the sin of the world!
Taking away the world's sin (Jn.1:29) shall make the world sinless. So, yeah, all will be saved.
Hebrews 10:26-27 – For if we sin willfully after we have received the knowledge of the truth, there no longer remains a sacrifice for sins
Does that say the sacrifice of Christ is "no longer applicable" forever & ever like a fictional unpardonable sin, or "no longer applicable" as long as it is rejected & not being applied?
Here's one opinion in that regard:
"The verb "sin" in this verse is present tense (as are the verbs "remains" and "will consume"). Since present tense in Greek typically indicates an ongoing, continuous action, the passage can better be translated as: "For if we continuously sin deliberately, after having once received the knowledge of the truth, there continuously remains no further sacrifice for sins, but a fearful prospect of judgment, and a fury of fire which will continuously consume the adversaries." "
"So if one ceases to continuously sin by remaining apart from the Messiah, then Messiah's sacrifice for one's sins becomes operative again. It is now available for one since one has stopped the continuous sin of apostasy and can now be united with Christ. (Note the parallelism of the continuous sinning with the continuous remaining of no further sacrifice; when the former vanishes, the latter does as well—and the same is true of a person who continuously fails to repent of sin in general.) Thus if an apostate (to Judaism or whatever else) ceases to be an apostate, he can be saved. There is no unforgivable sin taught in this text."
Hebrews 10 and 6
Another comment from the same thread says:
"My understanding of Heb 10:26 is simple. There is no further sacrifice for sins. Jesus provided the only sacrifice, and if we don't want that sacrifice, well -- there's nothing else. There is no further sacrifice for sins. That's it; take it or leave it (but eventually you WILL decide to take it because the alternative simply makes no sense at all.) The fearful judgment (v.27) will consume the adversaries; it will not consume the beloved (the world for whom God gave His only begotten Son). The last adversary is death and that too will be consumed, leaving nothing but life!"

"There is no more offering for sin...there is left no place for the Levitical sacrifices under the new covenant." (Vincent's Word Studies)
Heb.10:12 But when this Priest had offered for all time one sacrifice for sins, He sat down at the right hand of God.
Heb.7:27 Unlike the other high priests, He does not need to offer daily sacrifices, first for His own sins and then for the sins of the people;
He sacrificed for sin once for all when He offered up Himself.
"there is no more offering for sin; there may be other offerings, as of praise and thanksgiving, but none for sin; "there is no need", as the Syriac version; or there is not required, as the Arabic version; there is no need of the reiteration of Christ's sacrifice, nor will he be offered up any more, nor of the repetition of legal sacrifices, nor ought they to continue any longer. The Jews themselves say (w), that
"in the time to come (i.e. in the times of the Messiah) all offerings shall cease, but the sacrifice of praise.''
And one of their writers says (x), when
"the King Messiah, the son of David, shall reign, there will be no need of "an atonement", nor of deliverance, or prosperity, for all these things will be had;'' (Gill's Exposition of the Entire Bible)
Hebrews 10:18 Commentaries: Now where there is forgiveness of these things, there is no longer any offering for sin.
The NIV Study Bible notes to Heb.10:18 say that "no additional sacrifice for sins is needed" {p.1870}.
Heb.10:26 For if we wilfully persist in sin after having received the full knowledge of the truth, there no longer remains in reserve any
other sacrifice for sins. {WEY}
"there remains no further sacrifice for sin": since Christ's work on the cross dying for the world's sins is the sacrifice that ends all sacrifices for sin, there is no other place to go but Christ for the forgiveness we all need, both at salvation as unbelievers and thereafter as members of His Body.
This is allegedly from Marvin Vincent's commentary in his New Testament Word Studies:
"The writer does not touch the question of the possibility of God’s renewing such to repentance. He merely puts his own hypothetical case, and says that, in the nature of such a case, the ordinary considerations and means which are applied to induce men to embrace the gospel no longer appeal to the subjects supposed. He contemplates nothing beyond such agencies, and asserts that these are powerless because the man has brought himself into a condition where they can no longer exert any power."
"Whether God will ever reclaim by ways of his own is a point which is not even touched. Destruction of the faculty of spiritual discernment is the natural outcome of deliberate and persistent sin, and the instrument of its punishment. Note, “renew unto repentance.” God promises pardon on penitence, but not penitence on sin."
Hebrews 10 and 6
"The assertion of Kurtz, that, if this remark were true, the author would be expressing “a dogma in its consequences truly subversive, and destructive of the whole Christian soteriology,” inasmuch as it would “imperatively follow therefrom, that even under the New Covenant only those who transgressed from ignorance and error could find forgiveness with God for Christ’s sake, while all who had been guilty of a conscious and intentional sin must beyond hope of deliverance fall victims to the judgment of everlasting damnation,” is a precipitate one, since the special limitation within which the expression ἑκουσίως ἁμαρτάνειν was used was naturally afforded to the reader, quite apart from the investigation already preceding at Hebrews 6:4 ff., even from our section itself." (Meyer's NT Commentary)
"there remaineth no more sacrifice for sins] Lit., “no sacrifice for sins is any longer left for them.” They have rejected the work of Christ, and it cannot be done for them over again. There is one atoning sacrifice and that they have repudiated. He does not say that they have exhausted the infinite mercy of God, nor can we justly assert that he held such a conclusion; he only says that they have, so long as they continue in such a state, put themselves out of God’s covenant, and that there are no other covenanted means of grace. For they have trampled under foot the offer of mercy in Christ and there is no salvation in any other (Acts 4:12)." (Cambridge Bible for Schools and Colleges)
"There remaineth no more sacrifice for sins (οὐκέτι περὶ ἁμαρτιῶν ἀπολείπεται θυσία)"
"Of course not. For the Levitical sacrifices are abolished. It is Christ's sacrifice or none." (Vincent's Word Studies)
Hebrews 10:26 Commentaries: For if we go on sinning willfully after receiving the knowledge of the truth, there no longer remains a sacrifice for sins,
Those who had thrust away faith with a good conscience, and had made shipwreck of the faith, were given over to Satan that they may be trained not to blaspheme {1 Tim.1:19-20}. This seems to be an example of willfully sinning after knowing the truth, as in Hebrews 10, yet those who do such were still being trained or disciplined for their own good. The NIV Study Bible says such action was more remedial than punitive. Similarly is 1 Corinthians 5:4-5:
4 When you are gathered in the name of our Lord Jesus and I am with you in spirit, along with the power of the Lord Jesus, 5 hand this man over to Satan for the destruction of the flesh, so that his spirit may be saved on the day of the Lord
1 Tim.1:19 having faith and a good conscience, which some having thrust away, made shipwreck concerning the faith,
20 of whom are Hymenaeus and Alexander, whom I delivered to Satan, that they may be taught not to blaspheme.
Psa.119:67 Before I was afflicted I went astray: but now have I kept thy word.
68 Thou art good, and doest good; teach me thy statutes.
In Hebrews chapter 2 we read of a "fair reward" for the disobedient:
2:1 Therefore we must more exceedingly be heeding what is being heard, lest at some time we may be drifting by. 2 For if the word spoken through messengers came to be confirmed, and every transgression and disobedience obtained a fair reward
Heb 10:26b no longer a sacrifice for sin (NAS). Compare the same Greek words at Mk.9:8 translated "any longer":
Mk.9:8 And suddenly, looking around, they saw no one any longer, but Jesus alone with themselves.
Did they not see any man "any longer" after that time except Jesus? Obviously they did see other men, so the words "any longer" does not support the contention re Heb.10:26 that God would "never" again allow some to be beneficiaries of the sacrifice of Christ.
26 For at our sinning voluntarily after obtaining the recognition of the truth, it is no longer leaving a sacrifice concerned with sins, 27 but a certain fearful waiting for judging and fiery jealousy, about to be eating the hostile. (CLV)
Hebrews 10 For the law, having a shadow of the impending good things, not the selfsame image of the matters, they, with their same sacrifices which they are offering year by year, are never able to perfect to a finality those approaching."
Heb.1:2a in these last days has spoken to us in His Son, whom He appointed heir of all
Heb.1:3b When He had made purification of sins, He sat down at the right hand of the Majesty on high
Heb.2:2b every transgression and disobedience received a just penalty
Heb.2:6 But one in a certain place testified, saying, What is man, that thou art mindful of him? or the son of man, that thou visitest him?
7 Thou madest him a little lower than the angels; thou crownedst him with glory and honour, and didst set him over the works of thy hands:
8 Thou hast put all things in subjection under his feet. For in that he put all in subjection under him, he left nothing that is not put under him. But now we see not yet all things put under him.
9 But we see Jesus, who was made a little lower than the angels for the suffering of death, crowned with glory and honour; that he by the grace of God should taste death for every man.
14 Therefore, since the children share in flesh and blood, He Himself likewise also partook of the same, that through death He might render powerless him who had the power of death, that is, the devil,
15 And might free those who through fear of death were subject to slavery all their lives.
Heb.10:28 A man that hath set at nought Moses' law dieth without compassion on the word of two or three witnesses: 29 of how much sorer punishment, think ye, shall he be judged worthy, who hath trodden under foot the Son of God, and hath counted the blood of the covenant, wherewith he was sanctified, an unholy thing, and hath done despite unto the Spirit of grace?
Generally capital punishment under Moses' law was by stoning. Stoning to death is not a very sore or long lasting punishment. People suffered far worse deaths via the torture methods of the eternal hell believing Medieval Inquisitionists and the German Nazis under Hitler.
Therefore, if the writer of Hebrews believed that wicked, rebellious, Christ rejecters would be punished with something so monstrous as being endlessly annihilated or tormented, he would not have chosen to compare their punishment to something so lame as being stoned to death. Clearly he did not believe Love Omnipotent is an unfeeling terminator machine or sadist who abandons forever the beings He created in His own image & likeness so easily.
Like the song says; "There is power power in the blood of Jesus." More power and a better plan, than the nominal church can even believe. To have ears to hear, one must loosen the death grip on what they believe."
