Re: .224 100 grain wildcats 7 twist No Go
That report does seem strange and also confusing, as I seem to recall Kirby getting good accuracy in his 7 twist barrel at velocities up to 3,100 fps. Have you measured the twist to make sure that it is in fact a 7 twist?
I just did the maths, and 3,000 fps in a 7 twist barrel produces 308,571 rpm, and in a 6.5 twist barrel it produces 332,307 rpm.
Perhaps my 6.5 twist Krieger may be the right choice for my forthcoming .224 Clark. I was beginning to wonder if I had been too conservative in my choice of twist. Regards, Brian.
