6mm barrel diameters?

[itchyTF]

.236 vs .237
Is one better suited for something than the other? Heavy bullets, light bullets or what?
An inquiring mind would like to know.

Krieger barrels has the right answer if personal preference doesn't cover it. I always got the .236 bore and never tried the .237

I have always answered that it is the difference between shooting flat base bullets and boat tail bullets.

This excerpt is from member ALF but without his permission. Then I offer the link to entire thread:


"General rule of thumb is to shoot close range BR with the .237, cause most BR bullets are flat base with a pressure ring that runs the diameter up to around .2435 or even more.

Long range, for 600 or 1000, use the .236 cause most all shoot boatail bullets that have no pressure ring to speak of, so they run on the smaller diameter size, around .2430, give or take.

I had a good shooting barrel that measured .2367, and shot great with some of the first 105 VLD's that were fat, and measured .2435. All was good......til I ran out. I had several other lots of 105's, up to .2433 in diameter, but none shot as well as the originals. That barrel is now on a prairie dog gun, and all my Kriegers are .236.

Some claim there's no difference, but I'll gladly let them have the .237's......."
