Here’s a picture of my fired round. Does this carbon ring on the neck look normal/ anything that should be concerning, even if it isn’t is there ways to have a clean neck after being fired?The bullet is seated .020 off the lands. .002 shoulder bump, ann
ealed and trimmed every firing, I used a bushing neck die to size neck to .002 neck tension. I get around 3040FPS with Retumbo and 175grain Nosler ABLR.
Those are good stats. I wouldn't want to poke the bear too much other than cutting the donuts out say every second firing as recommended by a bullet Smith. Great numbers either way have fun
It’s not mild. with the 175gr bullets chambered in 7mm remmag I’m getting 3000ish FPS with retumbo and around 2940ish FPS with h1000. Maybe the neck in the chamber is around sammi max so it has lots of clearance in the chamber. Perhaps when I shoot this barrel out I can request it to be at sammi minimum when I get it chambered and hopfully that’ll fix that issues. But when when it looks like that it’s giving decent ES and SD as shown in the picture, just never really seen carbon rings look like that.
Is this happening on all your rounds?
