Am I gonna run into pressure issues?

[JCH]

I am loading up some 223 AI ammo for testing. I am using R15 and moly'd 75gr Hornady Amax's with Magtech 7 1/2 small rifle primers.

I started at 24.0 and went in .2 grain incriments to 25.2

Just want to make sure that I am not going to get into high pressures when getting into the last groups.

Can anyone help me out?

I'll hopefully have QL in a week or two, but I'm sure you'll have the answer by then.

Honestly, QL is good and helpful at estimating pressure, but I would never trust it vs. what I'm actually seeing for pressure signs. I'd just shoot the 24 grains and work my way up, feeling for sticky bolt lift, watching primers, etc. If you have a set of calipers take those too, keep an eye on the case web dimensions, any jumps would indicate excessive pressure to me and I'd back off quickly.

By the way, I don't think that case web/head expansion is a greatest way to watch for pressure, but it is one gun in the arsenal. Check out this thread, about 4th post down, Ken Howell.

JCH,
I made a similiar request a few months ago and was informed that the vendor for Quickload had issues with people sharing data. Hard to believe but it is so!! See IMPORTANT INFORMATION REGARDING QUICKLOAD thread under Ballistics. Just a Heads-up.
