What's the bbl life on a 7 mm mag as I am looking to get one
If you are using it for hunting, the rest of your life.
I was thinking for hunting and some target shooting but more in terms of rounds I like to shoot a couple times a month or so
What is a bbl? Sorry I've heard this a lot lately and I'm curious
Bbl is a industry abbreviation for barrel
Depends on how you use it. If you shoot 20 rounds in 5 minutes and do that every couple of weeks it will last a few hundred rounds. Getting it hot and continuing to shoot a bunch can be detrimental to the throat. Think of prarie dog hunting where you might shoot 100 rounds of high pressure, high velocity ammo in a half a day. THAT is what will "shoot out" a barrel. The 7mm Rem Mag is not particularly known for burning barrels partially because it is not really a varmint cartridge adn does not get shot like a varmint cartridge.
3 to 5 thousand rounds
Sweet the info I ws looking for ty
I have a custom 7 mag that was capible of the same very small groups as a hunter 15 years later. A shoot it to check before season or when traveling and hunt only.
"Rate of fire"....prolly has more to do with brrl life than anything.
One of my sons got a 7mm in a TC.Using factory ammo as a source for cases.....has been a slight problem.Its loaded so hot from the factory that case "life" seems to be shorten'd.Iows,if reloading...you'd be money ahead to start with fresh cases.Its one of those calibre's thats pretty hot loaded from the factory.That and along with headspace issues(belted).I was just a little suprised at how fast cases showed signs of failure?
Stainless or carbon steel?
I agree. It is not a range gun, it is a hunter. I just showed my F series Savage 110 to a few friends. They were blown away at the rifle in general. What really got one was the weight. It is a Sierra lite, only made for 2 years in the early 1990's. I bought it new. Still as pristine as the day I bought it.
I'd have the chamber checked. I've used plenty of factory ammo and never found it "hot". Headspace is only an issue on any cartridge if there is an issue w/ the chamber. Also, you should Aneal the cases before reloading.
Don't have headspace gauges in this cal,but have cerosafe...I may check chamber.
Yes,need to anneal...being lazy.Just not used to case failure @5 loadings,first-factory,subsequent loads were "starting" loads.Case separated at base.
