Thread: load deveoplement for 243

Yep remmys are 9 1/4 and seem too love the 105s.... And like sneeze said it was/is 500m+ where they fall apart with slow twist....

However I do expect ur getting prehistoric speeds with 38gn of 2213.. Id work up until u get pressure, failing that I got 3120fps through mine with 48gn n165 but that was "warm" so start at 43gn....
