IMR4198/H4198

[fisher1]

I'm currently shooting 50 gr of H4198 over 10gr of SR4759. My rifle is a Encore 4570 conv. with Savage plug. I've located a 1lb can of IMR 4198 locally and considering giving it a try. H4198 is unavailable in my area. I would continue to duplex load but looking for help with charge weights of the IMR version. My primers are W209.

I do 56 grains of IMR 4198 in my Patriot .45 with bullets in the 195 to 225 grain range. I'm using the W209 primers as well. Very accurate load with any bullet within the weight range mentioned.

I interchange IMR and H 4198 regularly , negligible difference in POI, I also duplex with 4759 either 6 or 10 grs. over 50 of 4198
