Mag fed 30BR neck clearance.

[Kevin1990]

So I had a lilja 30br chambered on my Kelbly atlas tac action, and I have 150 pieces of peterson brass that were turned for a bench rest 30BR. Both were chambered by the same smith with the same reamer with a .332 neck.

I checked my clearance with the peterson brass and a sierra 125 and a 125 TNT and I am at .3292 under a loaded round. Is .0028 enough neck clearance for a plinking/hunting 30BR? I feel like I've seen guys saying they were turning like .003-.004 clearance for that kind of 30BR rig.

Thanks fellas!

Should be fine

That is cutting it tight but it should work.
I run about 0025 overall clearance in my 30BR Benchrest Rifle. But that is turning necks insuring that every case is exactly that.

He is running .0028,.332 nk.

If this is a field gun don't put ammo in your pocket or drop in the dirt. Just one tiny piece of lint or dirt will jam the action. Most field gun users do .004-.005" clearance.
