The maxim bolt that came with my barrel has the correct specs.
I've haven't had any pressure signs handloading with my barrel.
Been using a pistol cleaning rod to smooth out the throat area.
I use a nylon brush covered by a patch with JB's on it and stroking it back and forth in the tight throat.
I clean a barrel a lot during the first 50 rounds so it hasn't been that much more than a regular barrel breakin.
I have shot the 123 SST's with 30.8 grains CFE at 2.233 COL and they were accurate and will fall out of the chamber now with the extra cleaning and throat brushing.
I wish it came with the throat being around 30 to 40 thou longer but it might work OK in the long run.
I won't need to worry about chasing the throat.
It shoots the short bullets like the 85 grain sierra very well.
