H4198 versus H322
I've been using some H322 with great results but need a bit more speed. I'm right at shoulder neck juncture with it but just not getting the speed I'm looking for; close, very close. I can't get enough in case to get what I'm wanting before running out of capacity.
H4198 is just a bit faster per burn rate charts. Will H4198 Extreme give me just that bit more speed needed versus H322 per case capacity or are they too close to make a difference? Or should I take the next leap and go for a significantly faster powder? The cartridge I'm working with is comparable in size to a .223 or .222. Thanks, George |

depends on barrel length and bullet weight, if a longer barrel a slower powder, in a number of cases I shoot my better velocity is attained with IMR 4198 over H4198 but I get better accuracy from H 4198

I use H4198 in 20 VT and 20 Tac and use H322 in 223 and 6x45. I value consistent accuracy over velocity.

I agree with ken158. Go for accuracy.

Give Benchmark a try.
