I have an M96 swedish Mauser with a 1 in 7 1/2 twist and slugged barrel at
.2655 groove diameter. I cast a 135gr. GC bullet from a Lee mould . I once tried 21-24 gr. of IMR4895 and had found 21gr. precise but went back to the range with same recipe and result at 100 yards weren't as good as previous.
Anyone with load data would be appreciated.
