22/6mm powder

[nastynatesfish]

looking for powder choices. I'm looking at bulkets 68-90gr. I've got a few hundred 75 amax. I can get 90gr smk local. I know it shows h4831 and h1000 for 75-80s. Wondering if retumbo can be used also since I've got a bunch of it from my 6-06.

Retumbo may be a bit slow, but it might work with the 90's, I used RL-25 in mine with the 80 SMK's...

I'm shooting Retumbo in a 22-243AI under 80gr bullets. I'm getting great speeds and great accuracy with it. RL 25 works well in my gun as does IMR 7828. On the other hand though H4350 gives me good accuracy as well and the speed isn't far from the slower powders. I just run the slower powders b/c I feel it helps me to deter some throat erosion.

I had good luck with RE 22 and the 75 Amax and the 73 Berger.
