[QUOTE="B23, post: 846928, member: 13222"] Kirby, would your best guess put RL33 closer in burn rate to US869 than it is to Retumbo?? I bought a 8lb jug of RL33 last winter when it first hit the shelves but as of yet I haven't used any. As you know, I'm a fan of US869 but your testing results have sparked my interest and if I can use less powder, have it burn cleaner and get better FPS as well as ES numbers, why wouldn't I want to give it a try. My 338 Lap Imp has a bit longer throat than your tester does. Mine isn't all the way out to 4.050, I'm at 4.010 and that's 10thou off from touching. Do you think 106gr of RL33 at 4.010 ( ten off) would be ok to start??? I may have to fill a few cases with RL33, cap them off with 300gr Bergers and strap the Magnetospeed on and see what happens. This powder could make the 300AX you built us and even hotter hot rod. With her longish throat and US869 it's currently running 3250's pretty easy. Could be very interesting to see what RL33 does in it. Thoughts???? [/QUOTE]
