Okay, I’m trying many loads for my AR trying to find that perfect powder-bullet combination. I decided to try Hornady’s 75 gr AMAX. (I have a 1:8 twist so I’m exploring 60 to 80 gr bullets). I set my seating die to give me an ogive length of 1.82; after loading thirty rounds it struck me that the bullets looked really long. I tried them in my MagPull magazine and sure enough … to long! So I adjusted the seating die and kept seating the bullet deeper and deeper until it fit in the mag. Then I realized that in order to get it in the mag the ogive of the bullet is down in the neck of my case. Picture the case extending past the point where the bullet has tapered below .224. The bullet is going to have a hell of a jump before it engages the lans; so I’m thinking that could lead to accuracy problems (possibly function as well?). Secondly, I set these bullets over 23.5 grains of IMR 4064. This load was compressed at the first setting of the bullet. Now it’s really compacted, could that be a problem? Appreciate any of your thoughts.

When primers were getting scarce I picked up a brick of CCI Magnum 450 Primers. Has anyone noted and change in accuracy, pressure, standard deviation, etc when using magnum vs regular primers in the 223/5.56?

Thanks for the help. Just a point of note: I am fully accepting the fact that I'm sacrificing accuracy to get a high volume of rounds. These are just for recreational shooting. If I want to make the best group I'll sit down and hand load each round.

Hello all, new to the forum! Sorry if the question has been addressed but, I could not find any reference in the threads. What is the typical method of dispencing powder in a progressive press? Do some meters work better than others for handling the range of powder types (cylinder, ball, flake, etc)? I'm looking to start doing a lot of reloading of .223's for my AR-15 and some of the powders that work the best are extruded powders and do not work well through a lot of standard meters. So any thoughts would be helpfull. Thanks!
