Barrel Frosting...

bwanamrmBarrel Frosting...
Could someone please define this for me and discuss it's implications in older firearms? Thank you.

jimatcatfound this on the cmp website..... Frosting is the result of myriad tiny pits that are usually the result of using chlorate-primered ammunition in the firearm and not always properly cleaning it soon enough after use.
Looking at a light reflecting thru a frosted bore is reminiscent of light reflected off of frosted glass.
Usually the main issue with frosted bores is that it more difficult to get them clean.

MacD37Bwanamrm, the so-called "FROSTING" of the bore of old rifles just ahead of the neck of the chamber, to a short distance down the bore toward the muzzle, is caused by very hotly burning powder. Commonly called "Cordite burn"!
Cordite burned very hot, and caused the frosting. As long as the bore is clean past a few inches of the bore ahead of the chamber it doesn't usually effect accuracy.
The effect of Murcuric primers is to the full length of the bore, if not cleaned properly, and quickly after fireing ammo that is so primed. A solvent soaked patch run through the bore of a rifle that comes out GREEN is an indication of murcuric primers haveing been used without cleaning. This does effect accuracy quite seriously.
Hope this helps!

500NAgree with Mac on this one.
If a gun had "frosting", it doesn;t worry me that much as long as it hasn't developed into deeper pits so that (deeper pits) is the one thing I look for.
Unless the barrel is really worn or some other problem, I haven't noticed it affect accuracy in the guns I have used.
Definately harder to clean but with the products on the market we have now, it's a lot easier.

bwanamrmWickedly clever marketing plan the folks at the Fine Gun Library at Cabelas' in Buda have dreamed up! Leave the bloody doors to the gun cabinets unlocked so the weak minded and weaker willed can handle the merchandise! Might as well put fish hooks in there...

BiebsHey, Tell Hal Skaggs I said Hi. I see he has an older 577 Jeffery there that's interesting, but the numbers on the action (177-650) indicate if was designed for the lightest 577 load. Still a cool rifle with enough power (650gr Woodleigh BP bullet at probably 1,900 fps)to do Cape Buff. A few other interesting pieces he has, too!
