Lapping the bolt lugs to the lug abutments to improve surface contact

308 Win, cut rifled barrel with prototype rifling. This is not yet available but will be very, very soon. This rifling profile has very interesting attributes that equate to some pretty neat benefits to the shooter. We are collecting as much info as possible so this is represented as...

338 Lapua, cut rifled barrel with prototype rifling. Not available as of now...

260 Rem with "not yet released" rifling profile. This is a buttoned barrel

223 Rem at 300 yards, Mullerworks 8tw. This is a standard production barrel the same at 565 yards last weekend. Load development......Done!

Using this logic you should only buy barrels from those that have their own steel mill, refine their own crude into cutting oil, and are the exclusive installer of their own barrels, Brilliant!

The BAT VR does have a flat bolt nose and a flat (no counterbore) breech. If you put a case in the chamber and provide a protrusion measurement I'll double check my records when I'm back in the shop to verify

X ring accuracy in Bradenton English Rifles in Wachula Both in the central FL area

If the tenon is .690-.700 it's probably a BAT, VR or similar

I shoot the 100 grain Barnes with retumbo, never even looked at anything else, it was right there. H1000 should work too

I'll use Remington as an example: I bore the thread crest off, then re-cut the threads till a 1.072 plug gauge screws in completely. Then go very slowly till a 1.074 plug screws in with a slip fit- little to no wobble. I'll call this 1.075 on the action and stamp it so on the under side of...

Benchmark makesbutton rifled barrels

If the rings you are seeing at the muzzle are in both the bore and the groove, it's likely they are button marks from the rifling process, you may have not seen this before because you had not scrutinized the barrel in the past (or the lapping could have cleaned away some long term fouling that...

-5 groove, probably R form -2771 or whatever it says would be serial number (pic went away when I started the reply) -Steel lot "L"? (Internal info for them) -"S" for stainless,? I don't know why it wouldn't say SS

You could call either X Ring Accuracy or English Rifles, both would do a fine job for you and are quite close to Tampa as well
