Re: 270 WSM Winchester vs Norma brass
Well, 65gr of R22 and Norma brass with 130gr Accubond came out to 3050 fps. Which was about 200fps slower than the Winchester Supreme Elite 130gr Ballistic SilverTips. Going to pull the rest of the bullets and add 3 more grains and try again. I am at 2.76in COL and use CCI 250 primers.
Winchester offers the 140gr Accubond in factory ammo, but not the 130gr.
I am beginning to think Nosler data must use the fastest barrels ever made, their 6th book says 65gr is max at nearly 3400fps. 64.5gr of R22 is min load in Lyman 49th data at 3200fps, and they post 68gr as max.
Win mdl 70 Super grade was a joy to shoot. Recoil was much less than any comparable rifle I have shot.
Carter Country in Houston has ton of powder, bullets, and primers. Powder is a bit cheaper than recent, bullets slightly more. Primers are 38$ for 1000.
