OEM barrel break-in
Posted: Mon Dec 06, 2010 1:46 am
I have on hand almost everything I need to sweeten up a new still unfired Remington 700 VLS in 204 Ruger. It will be floated and pillar bedded to both the original laminated and a B&C A3 style stock, choice of Nikon or Leupold covering 4 to 20x in QRW rings on Leupold base, and a Jewell presently on the “A†spring as delivered at one pound. When done and if it will not deliver ½ MOA or less I want all other possibles previously covered so the only things left will be to have the action made perfect when being fitted with a real barrel in a 10 or faster twist.
The original plan was to break in the Remington barrel (shoot one - clean - until…) using Hornady factory 40gr. loads, only after doing all the sweetening. But now I can’t stand it any -- I gotta -- I mean, I really feel like I should have a before picture to compare with the after so back together OEM with glass and on to break-in.
For barrel break-in, would a milder load of 22.5 gr H322, 6 ½, new Hornady brass, with 40gr V-Max, ~.010 off the lands at ~3340 fps (similar to Nosler #6 listed as starting load for 40gr BT) be better (less abrupt) for the process than the HOT Hornady factory 40gr V-Max load listed on the box as 3900 fps? Or is HOT desirable for blasting away the goobers left from Remington’s fine machining work? I’ll also be forming new brass during the barrel break-in so special reloading for it will not be a total waste.
I have seven more powders on hand to choose from, 6 ½ & BR-4 primers, 32 & 40gr VM, 40gr BT, 32gr BK, and 26gr VG, 100 new cases to form, and enough toys to check and set critical dimensions. A single shot diet will be the usual norm, most of the time anyways.
I’m open to any OEM barrel break-in ritual or ceremony you might have to offer so long as it doesn’t involve getting naked any time soon.
