I agree with the use of IMR 4350 in the .270 WCF. I found that while I got more velocity with H4831, my best accuracy with 130-grain bullets came with 55.5 grains of IMR 4350, and with 150-grain bullets, 53.5 grains of IMR 4350 was best. This with Nosler Partition bullets.
In both cases,velocity was plenty adequate, even though less than I used toget with H4831.
Would you happen to have those velocity figures? I'm interested. Thanks.
Well, yes. I shot those loads in 20" Mannlicher-Sdhoenauer carbine barrels of 20" length and 1/9" twist. The 130's went 2950 FPS, and I got just over 2800 with the 150's.
