A semi-newbie needs some help.
Before I switched to Missouri I was using Midway 124 gr round nose cast with no issues. Then I switched over to coated from MBC, same weight, but the grooveless version.

Before, I seated to 1.135 and all was well. The new ones I seated to the same depth. Fast forward to actually getting to shoot them and I'm having troubles. Several times the slide would not fully seat forward, but would go with a push, the round would fire and maybe the next round, maybe after two or three it would be the same thing, slide not fully forward.
I finally stopped using that batch and went back to the plain cast bullets and everything was back on course, no more issues. I'm positive this is not a firearm issue, too many rounds was fired to rule that out.
I roll everything around in my head trying to think what could be different, not enough crimp/some flare left on those? Case too long? I check everything compared to the old bullets and everything is exactly the same. I remove the barrel and plunk test them and the old bullets will drop about .040 deeper. Now I'm perplexed.
I go to MBC website and notice on the page that it says these should be seated to approx 1.08. That was probably there when I ordered them, but didn't remember it if it was. Anywho, I can see that the shape of the new bullets is different. If I simply seat these to approx 1.08 will that fix my issue? These same bullets cycled fine though another pistol, but not the other.
Did I find my issue or is there something else I'm not seeing? Decreasing the case volume is not going to cause another issue will it? The load is 5.8gr of Accurate #5.
Thanks guys.
