SteveConversion ratio for IMR4350 and H4831
Anyone know the conversion ratio for IMR4350 and H4831 from Cordite?. Is 1.33 a good number for both of these powders? (remembering to start 5% lower)
Thanks!

500grainsWhat cartridge are you loading for? Perhaps someone already has 4350 data.

Dan,
Sorry about that. I should have included that info. 475 NE. (3 1/2 inch, not #2)

SteveRusty,
First off, thanks for the foam. It was on my front porch when I got home. I was tickled pink to find it there. Please let me know if I can return the favor.
I tried R15 last weekend and wasn't getting both barrels to get close at 50 yrds. Once I got to 83 grns (all with three grns of Dacron on top of the powder) it was getting close to max velocity. The barrels were still not converging, but getting closer.
Thought I'd try the other powders and see how they did.
