Re: is the twist rate wrong?
I think it is too fast. All of my 30 cal tubes designated for the heavier 30 cal bullets except one are 1-10 twist. I shoot 210's, 215 and 230 bergers out of them. The "other" twist is a 1-9.5 krieger 1.45 strait taper on my HG. I had it made as soon as I heard about the 230 berger. It didn't like them, but LOVES the 215 berger.
Just my .02!!
