[QUOTE="BrentM, post: 1682041, member: 61747"] I have a 22" 1:7.5 proof. Only 30 rounds down the barrel but minor testing shows 2900 should be a safe load with 147's and expect 3000 with 140's. I am testing retumbo, H1000, RL26. If you compare Hornady max loads with all 3, retumbo was fastest in my initial test. However, I also noticed some bolt lift below max on h1k and retumbo. I didn't see that with RL26 and am testing a little higher to see how it plays out. For comparison my 20" proof creed is running a 140 at 2800. I expect there to be about 200 fps between the 2.
