Well, the board is either fixed, or it's going to run terribly. Cross your fingers and hope for the best. I'm at my technical limit right now.

I'm going to slug my barrel in the AM and see what the size really is.

Roger on that, I need to few things together in order to slug this one

I just slugged my rifles bore. After six readings the bore is .312. The lands are close to .309 but not owning a three point caliper my readings are an estimate for the lands. So,the bullets are "land riding" which is not conducive for any great accuracy. I will load up some .312,.313 bullets and see how well it shoots.
I have several boxes of 7.62x39 124 grain bullets. They range from .309 to the max of .3105

Hmm if the bore is reading .312 on average, using some .312 loads on average should
I believe, tighten up the groups a bit more for ya. I m going to check some of mine x39 and see what they are reading at

I loaded up some Sierra 150 grain SPFB bullets that when deep seated and no compressing the powder will fit the magazine. They are .312. I have some .313 bullets but they are too long to load safely.
With the rifling twist of 1:10.5" there will be no problem of bullet stabilization.

I like these conical base IMI 7.62x39 FMJ bullets. The theory is they will bump up in oversize barrels. Not sure they make any .314" size bore gun a match rifle...but a good theory I guess.

Don't think these are mfg by IMI or anyone today.

The larger bullets did much much better than you'd think. Groups were noticeably smaller at 300 yards. I think using a larger than .310 bullet will really improve everyone's accuracy.
