My first post here folks, so be gentle. I purchased some Zero #136 (HAP style) bullets and happen to have quite a bit of Win231 on hand. Yes, I know it might not be an optimal powder choice but... it meters so well through my Dillon loader.
My question is regarding load data for the Zero 125 gr #136 bullet. I had read to use load data found on the Hogdon/Winchester web page for the HAP bullet. They list a starting load of 2.8 gr to a max of 3.3 gr of W231 at 1.069 for the HAP. However... I see a number of reports extolling a load of 4.3gr of W231, the Zero 125gr #136 (Conical) bullet at a length of 1.130 and 1050 fps, reportedly with no pressure signs. I imagine the big difference is perhaps due to the OAL of the loads... or the factory load data for W231 is awfully conservative.
Can any one also loading the Zero 125 gr #136 chime in on their favorite W231 loads and OAL ? Or... a powder combination that meters equally well in a Dillon that is substantially better then W231 ? I suspect Power Pistol, CFE Pistol, the VV powders, WSF, HS6 are likely contenders. These are for practice rounds... at this point.
Regards,
Mike
