Gunsmithing M14 muzzle wear gauge in a Remington 700?

[super-tac]

Can you use a M14 muzzle wear gauge to accurately measure the Remington 700 muzzle wear? If the lands are actually .300" it would make sense than this would be an accurate gauge. This is a stock Remington 700 SPS Tactical in .308

I've searched all over but can't seem to find this data. Any time you type in "muzzle wear gauge" into a search engine you get a bunch of people arguing about WWII rifles.

Any help would be greatly appreciated.

Thanks!

Can't really see why you would need to check your muzzle wear on a civilian or any bolt rifle. The reason the military traditionally checks the muzzle wear on M-1, M14's is these rifles are cleaned from the muzzle, with threaded STEEL rods. Most military rifles especially in peace time are worn out by the obsessive cleaning the military demands. Also recently the use of "blank deflectors" these clamp on muzzle devices push on the crown and tend to build up heat and carbon at the muzzle.

Normal cleaning from the chamber usually keeps the crown and muzzle in shape.

If you have crown damage you'll know it in the accuracy dept. A good smith can re-cut and lap it back in shape

If you are still concerned about this issue a .308 barrel is the same if its with-in SAAMI specs.

I believe Badger Ord makes a M1 multi gauge that has a muzzle gauge on it as well as other hand M1 specific items.

Here is a good article on how to use a standard throat erosion gauge to to determine muzzle erosion

Good luck

I have a M1 barrel gauge and my 700 has a wear indication of 0.8

From what I've been gleaning, the cleaning from the muzzle is not what is causing wear, the pressure/heat from the powder does this.

I'm basically trying to get a feel for how much this has been shot, how much life is left. Not that important really, just curious.

Thanks!

Any .30 cal gauge should work, as you have reasoned.

Readings are thousands of a inch, so "1" would be .301, "2" .302, etc...

For Garands/.30-06, they seem to say it takes over 1000 rounds of .30-06 to change the reading by one unit. So if you use something like 4 as a rough accuracy limit (it may be more) then you have lots of life left. Most US WWII barrels read close to 1 when new. A new Sako TRG barrel reads under 0.

Throat erosion will wear quicker than the muzzle, so that is probably the limiting factor. Unless you clean from the muzzle with mil-issued a jointed steel cleaning rod as already mentioned!

You should look at the muzzles of some of the old turk mausers. They have rod grooves that make them look like pouring spouts. The performance of a stick is the standard you should use to determine barrel life. The TE/ME and embark gages of the military are just tools to determine if the weapon is capable of safe use and of minute of man and most civilian folks put way too much stock in their readings. We rebarreled a Garand for a guy who was upset he bought an H&R and the bore measured almost a 7. So a new criterion barrel went on in place of a GI barrel that could hit a pie pan 8 out of 8 at 200 yds. Waste of money.
