Re: A good long range 22-250 load
The 12 twist rate is perfect for the Sierra #1365 bullet with a .8 factor. It might or might not shoot the new 53 grain Vmax that has a .29 b/c (it's very close to max). I shoot the Sierras with IMR 3031 at 3500fps to 3550 fps (load came out of an old IMR booklet). Seat the bullets within .002" of the lands, if not just barely touching them. The rifle has shot a lot of low twos, and a few high ones in a Savage 112BVs-s (the old one with the blue reciever). I have another 112 just like it but not the single shot, and it will do high twos and low three on a regular basis with the exact same load.
I have tried H414 and H380, but didn't group as well. Want to try 2015BR, as it's almost an interchange for 3031 (one is slightly faster)
