Are go- no go gages on belted magnums only different by 0.002" (no go being 0.002 longer)? I tried to measure the distance from the gage base to the flat and I came up with 0.005" but it is a little difficult to measure with standard calipers.
The reason I ask is I removed my remage barrel to have it threaded for a muzzle brake the other week. I reinstalled the barrel and went to go shoot to make sure everything was working properly to find out my previous load is shooting like dog crap. I know the brake will change POI but the grouping size was terrible.
I went back to make sure my case bottom to lands measurement didn't change and found out it has increased. The barrel only has a few hundred rounds of 7mm RM so I find it hard to believe the lands have moved ( to what i measured another 0.040"ish). I ordered a Hornady OAL gage to make sure over the using a sized case and having neck tension hold the bullet.
