Ok, so I was loading some .45 on my 650, and a friend came over to ask about life. Since he was already interrupting an energetic and productive reloading session, he went ahead and asked me to show him how easy it was to switch from said .45 to .223. Fun! Here's the rub: I should have said something to the effect of "hey its easy, but I'm a dud mentally and can't keep my head above water when you switch things up on me so let me show you later, ok?" but no- I quickly swapped the lower end, primer system, and went to dump about 300 grains of HP-38 into it's bottle, and proceeded to dump it into a jug of 5620grs worth of A2460. Now, I am wondering if I can still load the 2460/HP38 into some .223? I'm no expert but I would like to think that if I ran minimums I would probably be ok; But I am hoping that someone much more knowledgeable than myself can chime in. Have I ruined the 2460?
I realize that the hp38 is a much faster powder, but I am unclear as of yet what the pressure differences would be, and perhaps the risk is not worth the reward. It will sit, probably, until I come up with a good use for it, or unless someone in the know says I'm being overly cautious.
