Question for POP or others on .243 load

coyotetrapper · Oct 27, 2008

Could anyone tell me of a powder that I can get a legit 3,000-3,050 FPS out of a 26" barreled rem rifle? I have tried h-4831SC very accurate but I get 2930 FPS, anyone know of a powder without maxing it out to get this range out of a 90 grain bal tip? I would like it to shoot some flatter and at 3,000 FPS I would be happy as long as my accuracy doesn't go south! Thanks

4350, 4895, Varget 85-90 grain pills, save the 4831 and rl-22 for the 95+ bullets (in my experience)

Same here.

coyotetrapper · Oct 28, 2008

Thanks guys but looking at faster powders such as varget and 4895 with an 90 grain bullet I don't think I can hit 3050 and have a decent load density? Who knows maybe it would be accurate? I use 37.5 varget with the 80 grain bal tips and I get 3,100 fps, that is a load density of 78%, it works as I get awsome groups with this setup. I would be in the lower 70's% with a 90 as top 38 and I don't know if I want to get to max!

According to pop's info above h-4831 sc has a near max of 47.5 and a fps at 3208 so I will try this powder and go a little more than the 43.5 grains I have been using and see what 44 and 44.5 grains will give me? I;m betting I can get real close to 3,000fps in that range with my 26" barrel? I hope my accuracy stays the same as 43.5 grains is a whopper of a accurate load at 100 yards! Plus I'm saving some wear and tear with a slower burning pwoder on the throat correct?

The above is only a simulation. Your mileage may vary.

coyotetrapper · Oct 28, 2008

Understood and I don't like max loads but I will say your program and my cronograph have been very,very close! You must have a good program there POP! The most varinace I have seen from a load is 30 FPS compaired to your program! Much closer than most loading manuals for sure!
