Any idea how much the throat has eroded ? May be worth cleaning the throat with bore paste to see if that helps. Does your fire forming load still fire ok with no pressure signs? I did see you are using a barrel cooler so it looks like you tried to keep the barrel cool while fire forming. As...
Thinking to many rounds down the bore to be a chambering issue. Carbon issue or throat is starting to erode would be my WAG. Scrub with JB bore paste would be my next move.
Give GAP a call and see what they think. Thinking it would be odd for a rifle to leave GAP with a bad chamber. Get some JB or IOSSO bore past and scrub the throat out, should cure the problem. Has the rifle been shot suppressed?
I was measuring a new lot of 108 eld-m bullets today, got .2433 with my micrometer. They are with in .0001 of my last lot. With SAAMI spec of .2435 throat for the 6 CM that doesn't leave much room for debris. I've never had an issue with these bullets, they shoot great in my rifle. Clean every...
I currently have 4 rifles using H4350. I'm running to different 8 LB lots of powder with 2 rifles and using up some 1# cans on a 2 other rifles. 30-06 AI and 6CM are on the 8# lots, powders were purchased when rifles were barreled. H4350 gives me good case fill and great consistency in velocity...
This is a great option, get free components to fire form brass and get some trigger time. Sig would be my first choice, but have used Norma and ADI with good results.
I'm using your LRP 6CM brass with very good results. What are your recommendations for number of firings before annealing? Thanks for making a great product.
I've got 2 sets of Grabbers in use. One set going on 2 years, the other set have been on for two months. Pretty quite on the pavement, they flat work on gravel and off road. These are 10 ply rating.
JB bore past on a swab -it bore mop works good to polish dies. Brass brush with a patch wrapped around it works good to. Spin it with a drill and it doesn't take long if the die isn't in to bad of shape.
Have a barrel on order for a 6cm build. Talking to people who have used this, they say plan on 2000 rounds if loaded to max velocity . I ordered a 7.5 twist barrel, planning on running 90 to 107 grain bullets. Going to be using this rifle for predators. Next step will be trying to find a set of...
First thing is check your bolt face for pitting and give it a good cleaning. Have the lot number for the cartridges when you call Barnes. If the bolt is pitted I would be letting them know this as well. Rifle should be fine, Take it to a smith if your not comfortable inspecting it. The ejector...
