it's not that difficult
This sounds familiar. I’ve spent plenty of money on molds and a couple of different AR barrels trying to find a heavy supressed load that would feed and function. The bullets that feed OK tend to have fairly terrible accuracy because they have undersized noses that wobble down the bore. On the flip side, my NOE molds have noses that seem to be too fat.I think part of the problem with getting people to agree on an good AAC bullet is that none of the manufacturers can agree on a throat shape.
I got 20 molds that will fit and shoot well in the wifes Ruger.
I have like 2 that will even chamber in my AAC made rifle. [the LEE and the RCBS silhouette]
it really likes the 110gr Varmageddon bullet by nosler and the other brands like it though.
I'm surprised about the rcbs, because it will not chamber in any of the AR rifles I have tried it in.
it feeds,, it just won't chamber the nose all the way into the rifling.
I wouldn’t mind having one specialized AR upper just for a specific mold if I get a combo that works. I have a NOE 247 hollow point mold that I thought I might like to hunt with from a 10” suppressed AR. I just can’t get the little fat nosed SOB to work. With a little throating there might be enough room to take full advantage of it.it's either that or modify a mold.
I have taken and cut the nose off a couple of cast bullets and made a lap out of them before.
once you do that your kind of locked into one mold for one gun.
