Kirby did have problems with the 3 grove barrels but as I understood him to say they
were all fast twist for heaver bullets and the thin jacketed bullets came apart at high velocity.
Based on every ones experiance and recommendations I went with the slower twist for lighter
bullets hopeing I would not have the same problems.
So far I am pleased with the test I have done( break in loads were with 60gr .223 dia bullets)
and they produced a velocity of 3915 ft/sec and a SD of 6.
The next bullets I will try will be 50gr @ around 4200 ft/sec. and then 40gr bullets @ around
So before I could recomend 3 grove barrels I have to do more test.
I am still hopeing my experment is a success.
