Re: Rl-22 sensative

RL-22 is know to be quite sensative to temperature change. You will need to shoot some targets at varying temperatures and record the velocity changes. H-1000 is supposed to not be sensative, but I have done no formal testing with it in this regards. I have found both to be excellent slow burning powders.

H4831/SC is also very forgiving to temp changes.

Re: Rl-22 sensative

i have tested Re 22 and have found that it drastically affects velocity when used in different temperatures.
I will never use it again.

Re: Rl-22 sensative

I guess I'm always the exception every time someone asks this question. I've used RL22 in my 300WM in temps from over 90 to below zero. Never had a problem hitting what I was shooting at to over 600 yds. I do, however, develop my loads during summer when it's very warm outside. If you were to develop your loads when it was cold and then shoot it when it's over 90, you might run into problems. I also don't load it to max. It's then only powder I've shot in my 300. The only time I've had problems is when I was shooting on a really hot day. I blew a primer. However, this was also the lot# of powder that was later recalled by Alliant about 6-7 yrs. ago. Anyhow, it's the most accurate powder in my 300 and I've not seen the temp. sensitivity that everyone else has, so I will continue to use it. If you doubt it, don't use it as that will always be in the back of your mind when getting ready to pull the trigger.

Re: Rl-22 sensative

I love the velocity and accuracy I get from RL 22 and RL 25. I have been using them to load Weatherby calibers. The downside is not high pressures or sticky bolts but from summer to winter my groups change and so does point of impact. I'm tired of working up a load that shoots really good and next time I go to the range in a different temperature the point of impact has changed. Gonna try to get away from RL powders. I'm going to try H4831sc, Ramshot magnum and Ramshot Hunter. I'm not as concerned with top velocities as I am knowing where my bullet will hit. Anyone having good luck with VV powders? Are VV powders very temperature sensative? I really like VVN 133 in my 222, 223 and 224 Weatherby. Even gonna try it in 22-250.

Re: Rl-22 sensative

I just pour RL22 into the case until it spills over the top and then shake some out and seat the bullet. Sometimes primers blow, sometimes cases stick in the chamber and the worst part is I seem to always being having to clean animals and pack the meat out. Maybe I should quit using RL22 and change to something that doesn't cause me so much back breaking work.
