29 grains seems to be doing better groups and believe it or not less recoil I know that might sound funny but .5 Les grains of powder I can actually tell less recoil I might even go down 28.5grains of h4350. 29 grain muzzle velocity is 2920 can't wait to try it out at the further distances might be able to get to three hundred yards. the weather is in the 40s in Ohio it was in the 9° range last week too cold for me. 29.0grns works great fore 115 dtacs last year.
