RUM/SAUM/Nosler etc overbore maintenance

[micus]

Hey guys,

what do you folks with lots of experience with the heavily overbored cartridges do for maintenance/cleaning and longevity. I have heard lots of theories and as always am looking for input.

I have heard about guys cleaning the bore and throat with JB polish, guys letting copper fouling reach an "equilibrium," and as always guys who clean for carbon and copper after every shooting session.

I didn't buy a RUM for a lifetime of use, however, with that being said. I wouldn't mind getting the longest practical service out of It as I can before rebarreling.

Mike.

I have a 7 SAUM, but I don't clean it any differently than my other rifles.

maintenance and "longevity" are not necessarily related - If you want an over bore barrel of any caliber to last, shoot is as sparingly as possible and do not over heat the barrel, barrel steel becomes more subject to erosion the hotter it gets, the axiom is "if the barrel it too hot to comfortably hold onto then it's too hot" (but remember, they make new barrels every day and we need to keep the gunsmiths in business !) It's a pain to work up a new load for a new barrel but it's also a good excuse to shoot it - I used to shoot PD's with a good buddy who was so anal about shooting out is barrels that he would leave in the morning with 4, sometimes 5 rifles and switch rifles constantly (it was a source of continual ribbing for the rest of us) I have a 223 AI and a 243 AI that have thousands of rounds through them and still shoot as good as the day I got them, just treat them right - Occasionally I've become immersed in a "firefight" but one or two of those episodes will seldom shoot out a barrel, habitually will ....

Use a bore guide when cleaning and don't shoot excessive shots in a row. Let the barrel cool. I don't clean barrels often anymore until they lose accuracy.

I dare say that near as many barrels are damaged by erroneous cleaning techniques as shooting -- It does appear that this is the newer "wisdom" in barrel cleaning frequency
