Talk to Me about 7-mm-08 barrel life etc.

[Dogsniper]

i picked up a mausingfield action with a 7-08 barrel on it set up for Lapua brass and the 162 amax. I was wondering which powder will get me the most velocity and temp stability. Thinking of running this for matches when my 243 barrel is smoked . I don't think I'll have to worry about anyone else running one for my brass pick up I'm brand new to this caliber.

I imagine something along the lines of varget or a 4350 would be a decent choice for powder. Reloader 16 as well for a bit more velocity if I were a betting man. Basically all the powders everyone wants lol.

4k seems like a reasonable expectation?

seems like an unpopular gem. I have to RL17 as well.

I got 3200 out of my last 260 barrel.

Id guess 4000-4500 at least for 7mm-08

might be able to run a slightly faster powder like 308.
4064?
varget?
4895?

I bet barrel life is more than a 260 Rem and less than a 308 Win

Me too.

H 4350 ! seems to be the most temp stable and gives good velocity , I'm planning a re-barrel in 7mm SAW when my SPR starts going south . Given the barrel life of the round I may even opt for a Proof Research Carbon barrel if finances allow it !

I looked in the reloading depot section. Not much data but 4350 varget and RL 17 are mentioned

That is a relatively close guess. Moreover, shooting the rifle with less hot load and keep the barrel cooling will significantly extend the barrel life.

So looking like 3000 rounds give or take

I'd seriously think over 3k. I don't think, and have never heard of the 7MM-08 being a barrel burner. It's not a big over bore issue. Keep the velocity reasonable, and take advantage of the incredible BC's that the 28 caliber has. I think the 7MM-08 is far too often overlooked. My grandfather hunted with one for a very long time. Took everything from hogs/Western mule deer/elk etc. Never thought he was under gunned. The BC's of the 28 cal are some of the very best.

Rate of fire kills barrels more than any other factor , if you need to run a hot barrel you will reduce barrel life regardless of cartridge . That being said over bore cartridges have a shorter life span than non over bore choices unless you need to fire long strings of sustained fire then all bets are off !
For non competition 4K should be easily attainable .

I run 2208 (Varget) in my 7mm08 with 162 ELD match. It's a factory Tikka Varmint and the current round count is 4500.
It still groups great but velocity has lost about 100fps. Going in for a rebarrel next week.
