I believe it would be best if you stick to .223 level loads for your bolt rifle. I have a single shot that would puncture primers when 5.56 milspec/surplus military ammo was shot in it (1 or 2 out of 20) and other pressure signs were apparent. I sent it back to the factory and they replaced the barrel and checked headspace. I keep my reloads to near starting point, .223 data, and 50 gr. bullets and get 1"-1 1/2" at about 60 yards (very good for the old guy).
This was several years ago, before the .223 vs. 5.56 issue had been reported/resolved...
FWIW; I've reloaded some .223 with 45 gr. lead bullets and some WC820 and/or Unique to about 1,800-2,000 fps, for some really fun shooting; no report, no recoil, and pretty accurate.
