[QUOTE="Brent, post: 37224, member: 99"] Get some more brass and work up the load, or break a few down and reload them progressively lighter. Check for excessive pressure signs as you work up to the ones you have all loaded up at 100 grains. That is probably the most sane suggestion. The second most sane suggestion, okay, maybe the third or fourth, but clean your barrel well so pressure starts a little lower at first, then fire a few over a good reliable chronograph and compare MV and pressure signs to the load with a standard 200 primer. I would guess that you'll be fine, but if you notice excessive pressure signs early on... well, stop. I've seen pressure go higher using mag primers, but I've seen it lower just as many times too, and very often I've seen it simply remain the same... this while testing with the Oehler M43 and PressureTrace. Anytime one changes components he should start low and work up. I know, probably just preachin to the quire... I force myself to check, double check, then triple check components etc, and only one can of powder, primer and bullet is ever down on my bench at a time. Here's hopin you don't have to pull bullets. Then, will that load even shoot with the primer change? [/QUOTE]
