 as soon as I get by way of my existing 3031 I'll transfer to A better-metering powder anyway, I just needed to use what I hand readily available initial.   SS

That’s not to mention it’s just as easy to stuff a seventy seven-grain bullet to the heaviest scenario you’re reloading atop a complete charge of BL-C(2) as it's with the lightest bit of brass in the batch. Just that, in most purposes, you won’t come across a big variance than if you just segregate your cases by headstamp.

I suppose some individuals have even though. I've normally wondered if individuals just assume which they require compact base dies

it is a compressed billed (everything around 25gr with 3031 inside of a 223 Rem case will probably be a compressed demand) and desires to acquire a slight crimp in it. I have shot these loads crimped and un-crimped along with the crimped shot better than the un-crimped for a few rationale.

5 gr. RL-15 will not be as temperature sensitive as some Many others. I experimented with Varget, given that the charts showed it could generate heavier bullets a little more quickly prior to getting to max pressures, but I had been unable to get any greater precision with it.

I shoot pistols for the most part and practically all those are Forged loads. I'm not away from powder but would want to benefit from the 3031 in a thing and get sensible precision. Any recommendations? a great deal of what I've "browse online" reported that accuracy was inadequate in many calibers. Taken with a grain of salt of course.

The only motive I take advantage of inventory powders is for selected accuracy loads and/or reduced quantity loads, so finding the time to trickle and weigh each load isn’t way too onerous.

I now lean toward heavier bullets in my '06s, and I've included a 270, so I stock slower powders now. But there have been many years After i could have utilised only 3031 and been entirely fine.
