There is no powder that is EQUAL in burn rate and pressure. There are however powders that are SIMILAR. The powders are not close enough to sub data back and forth with though.
:grin: i'm trying to get powder for 110.257 AccuBond,.257 ackley.i have buddy using rl22,and i thougfht since i have,h4831sc,h4895,n165,magpro.that i might beable to use something smilar.have great load for 100gr pt with h4350,nice to have starting point with 110.larry
I just finished working with the 110gr accubonds and my 25.06. I started with imr4350 and couldn't get under 1 1/2" groups at 100yds no matter what i tried so i quickly abandoned that powder. Next i went to imr4831 and i got consistent 1-1/4" groups at 100yds but i did have one 1" group that looked promising so i noted all the data and moved on. Next i broke out the RL22 and RL19. I started to try the RL22 before anything else and now wish i had but like the saying "hind sight is always 20/20". The first several loads i worked up with the 22 wasn't that great but i continued on. I was beginning to notice a pattern in that the closer to max i got the tighter the groups were getting. Then it happened :shock:! I shot the best group i have ever shot in my many years of reloading. I usually shoot three shot groups when testing and if i find something good i'll load three more and shoot at the same target. The first two were touching and i thought, maybe i'm on to something here. Third shot went in the same hole as the other two and i now had one big hole in the paper. Man i was tickled pink :grin: . I went back into my shop and loaded three more just to be sure. I fired another one at the target and i now had a bigger hole. I seen no need to shoot the other two so i went and took the target down to drool over for a few minutes. I measured the four shot group with my digitals and it was 0.325 :shock: :grin: . As soon as i can get to it i'll take a pic of the target and post it. I had 40pieces of brass left so i loaded them all. I have definately found a sweet spot and a load that this rifle loves and i can't wait to shoot a deer with the 110gr AccuBond to see what it will do. Anyone who is trying to find a load with this bullet i would highly recommend they try RL22.
Just as note, every rilfe is different. Everyone I talked to said RL22 was great in the .280. Mine only didd so-so. When I switched to IMR7828, bingo, groups half the size & going a bit faster w/o pressure signs too. Good luck.
:grin: well i got to range today.results;5/8's inch best group so far.52 grns RL22,110 AccuBond,win case cci 200 primer,seat depth 3.018.i'll mess around and see if i can get smaller.
