I have been out of shooting for a few years. I just got back into it and I mostly shoot 40 S&W in USPSA but have gotten the 45 bug again.
My issue seems to be with case sizing or over all length. I resize a 45 case and it fits properly into a case gauge but after I load it, it won’t go in all the way. I have played with bullet seat length and the taper crimp. Same issues. I cut the case back to .888", as the Lyman reloading book suggests, it goes into the gauge too far.
Any ideas?
Thanks in advance.
what gauge? Ever check your gauges with gauges?
Personally I would double check your trim length and data just to be sure
size and load your ammo to your data and use the pistol your going to use them as your chamber gauge. I have been meaning to chamber cast a case gauge I have to see what comes out.
Its not "right" for sure. I bought it used and the manufacture wanted proof of sale before doing anything about it. O well
Remember though theres a lot of different specs involved
Your gauge is basically a chamber so it should be .898" min with a Max of .920" per SAAMI your CASE max length is .898" with a -.010" allowance or min of .888"
So if your case gauge is made correctly your .888" trimmed cases will fall a bit more into the gauge.
Case mouth max dia .4730"
Now toss in all the different bullet choices and the spec variances with the bullets and you can have some fun, use your pistols chambers as gauges.
SAAMI has a whole section on gauges also.....
