Greetings.
Just got a new bacth of round nose 230 bullets from Rock Mountian Reloading. Have been using them for years with absolutely no issues.
New batch is much "rounder" than the previous.
I have been seating them to 1.274 with the older bullets. I seat first to depth and then taper crimp. i check each and every one for proper chamber with a spare barrel. I always use 4 gr of Clays.
The new batch of bullets engage the rifling closer to the bullet tip. I end up having to seat them at 1.20 before the case will head space correctly in the chamber. That means that there is .07" less space in the casing. They are of course noticably shorter.
I asked the guy at RMR if he thought there would be any problems with overpressure and he said "It will be okay to seat it that deep. It's such a low pressure round anyway and I'm assuming you aren't trying to load +p+ loads for it right? It may increase pressures a little but it shouldn't be so much that it will hurt anything. What gun are you shooting these from?"
I told him that I shoot these from my Kimber 1911's and he said "Yeah, your kimber can handle those just fine."
Not that I doubt him or assume that he is an expert, I wanted to ask the forum what the thoughts were.
Thank you for your opinions. I can post pictures if needed.
