[QUOTE="Bravo 4, post: 1783344, member: 8873"] Not trying to be rude with this, just speaking from experience (15+ years loading .338 Edge and RUM). Switching from H1000 to 8133 didn’t cure your pressure problems, you just simply started too high with H1000. Starting at 89.5 was too high for your particular rifle. My .338 Edge ran at 90 grains H1000 and that was about as hard as I wanted to push it, primer pockets gave up after 3-4 firings. My buddy’s goes up to 91 grains, but is throated longer. I’m not saying that H1000 will give you better performance (speed) than 8133, I’m just saying it was operator error that you got pressure with an initial load. I actually am running 8133 in my RUM and it isn’t giving me the speeds I want. But then again, that is my fault (operator error). I’m shooting too light a grain bullet for that powder and not maximizing its potential. Just an FYI, 8133 has mirrored RL25 in my rifle with same velocity for a given powder charge with a couple different bullets. Now in saying all that, if you are getting 2900’ish fps with the Edge and 300 grainers (no matter the powder) then I would be happy with that and try adjusting seating depth and see if the groups tighten up. Then shoot it at distance to see if the accuracy holds up. [/QUOTE]
