[quote=curdog4570And, FWIW, a 244AI dispensing 55 gr B T's in excess of 4k fps is the epitome of fast twist-short bullet technology.
hm.Im confused.
I have a 244 AI,but the barrel is twisted 1-12,would be good for 55 gr,doesnt work for 100 gr.
why the reference to fast twist? [/quote]
Because my fingers worked faster than my brain.
I had a really accurate 6MM Rem 700 that I had Improved. It shot the old Flat Base 100 gr. Noslers like dream, but I had it built on a Long action.
I gave it a friend and had one built on a short action 700, but when I picked it up from my 'smith, he had stamped the barrel "244AI", because it was a 12 twist. He was a B.R. and P D shooter and he mentioned the 55 gr B T as a good choice for P D's on calm days.
It was to be my "walking around" Whitetail rifle and occasional P D shooter, and works well for that. I put a 4.5 X 14 Loopie on it and shoot the 70 gr. B.T. for varmints and fireforming brass at P D towns.
The 85 gr. Nosler Partition is the heaviest bullet it will shoot accurately but they get the job done. I killed two Whitetails with it this year, one at 240 yards from a blind, and one at 140 yards offhand. Both one shot kills.
Sorry about the "fast twist" error.
