Yes. Calvinists use the KJB as much as anyone else, although if they had a choice they would stick to the Geneva Bible.
But Calvinism is not the issue here. The issue is to show that there are good reasons to use the KJB exclusively in order to avoid errors.
No one should claim that it is "inspired" (a "God-breathed" translation). But all should admit that it is the only faithful and trustworthy translation in the English language at present, because it fairly represents the majority of Hebrew and Greek manuscripts. And it also has many qualities that make it an excellent translation. Even the History web site supports this position:
Emerging at a high point in the English Renaissance, the King James Bible held its own among some of the most celebrated literary works in the English language (think William Shakespeare). Its majestic cadences would inspire generations of artists, poets, musicians and political leaders, while many of its specific phrases worked their way into the fabric of the language itself.
Even now, more than four centuries after its publication, the King James Bible (a.k.a. the King James Version, or simply the Authorized Version) remains the most famous Bible translation in history—and one of the most printed books ever.

So much for the detractors of the King James Bible.
Granted, I believe the Pure Cambridge 1900 is the seventh and final purification of the KJB editions and not the 1769 Oxford by Blayney (i.e., the Authorized Version). While all previous six KJB editions are true (despite small minor word differences), and corrections in printing errors, the Pure Cambridge Edition KJB is the true final settled Word. The difference between 1 John 5:8 between the Blayney Oxford vs. the Pure Cambridge by A.W. Pollard is considerable.
1 John 5:8 in the Authorized Version (Blayney Oxford) capitalizes the word Spirit.
1 John 5:8 in the Pure Cambridge (A.W. Pollard) places the word “spirit” in lowercase.
While the Oxford is correct, the Cambridge Edition KJB offers a more clearer truth.
1 John 5:7 is the witness (or record) of God in Heaven (with God being three persons and yet one God).
1 John 5:8 is the witness of man on the Earth with him being made up of water, blood, and spirit. Note: Blood and water came out of Jesus when His side was pierced, and Jesus yielded up His spirit when His body died.
1 John 5:9 says that the witness of God is greater.
So…
Verse 7 is talking about the witness of God.
Verse 8 is the witness of man.
Verse 9 says the witness of God is greater.
Granted, there are other subtle small updates that shows a clearer truth, as well.
