Checking Hodgdens data, I was actually already in the +P range and beyond it with yesterdays loads. They specifically tested a Berrys DEWC and my 4.7 and 4.9 grain loads were above their maximum of 4.6 grains. Both of those were my most accurate, coming in at 2.3+” from 25 yards. I used the Hodgden data for a standard pressure load with a Laser Cast HBWC, but used the longer COAL given for the Berrys DEWC, 1.145” vs 1.231”. I guess I got lucky. No pressure signs and the primers were rounded and looked like my pistol power 30-30 primers (6 grains of W231 and 135 gr C&C bullet).
First off, how is there such a difference in charge? I guess it’s the extra volume afforded by the hollow base coupled with the increased difficulty of pushing a copper plated vs cast and lubed bullet?
Looks like I’m back to W231. Hodgden only has data for the Hornady HBWC. I’ll use Lyman data since they have solid cast BNWCs at 148 and 150 grains. For all the stuff people say about it, Titegroup is starting to look more appealing by the day. It’s listed as most accurate for the 150. W231 did not do well with HBWC from 38 Special cases but is great from 357 Mag cases. Might as well try both. I’d really like a good target load from the 38 Special case. I still have quite a few even after giving away a few boxes.
