[QUOTE="AZShooter, post: 823987, member: 5219"] I have used RL-33 quite a bit and it is slower than retumbo. RL-33 requires approx. at 7- 9% more powder to duplicate retumbo velocities. (that was the average amount of powder for a 7 rem mag, 6mm-284 and 257 weatherby I tested) Alliant load data only has two loads listed for the 7 rem mag: 7MM rem mag 175 speer sp 75.2 gr RL 33 @ 2909 fps 7MM rem mag 175 speer deepcurl 73.8 gr RL-33 @ 2853 OAL for both is 3.290" If you aren't getting any more velocity with more powder than there is no point in adding even more, you found the max in this case. Quite frankly this powder is a bit too slow for your rifle BUT it will still work. If you cannot get other powders use it. I tried it in my 24" 7 rem mag using a moly coated 162 a-max. I had a load with retumbo and wanted to compare them. Retumbo 72 gr vel 2975 RL-33 worked up to 79 gr for vel of 3000 BUT the amount of compression caused the bullet to be seated out to the point it wouldn't fit the mag box! It was easy to conclude that RL-33 wasn't to be used with that weight bullet. I would just try to refine the load by tweaking seating depth and use it. [/QUOTE]
