Re: Barrell Life 338 rum vs 300 rum

Since the 338 Rum lags about 100 FPS behind the Edge with the 3oo SMK I'd say that the Rum isn't quite the equall of the Edge . I've alo spent my life in the shooting sports and I'm not buying the "obsolete" tag

OK now that we've established that one of you manufactures and the other is a consumer and that somehow 6-8 grains is splitting hairs and insignificant but, the 100fps it gets you is significant do either of you know the answer to the gentleman's original question on barrel life 338rum and edge?

I believe that LTLR said you could not wear out a 338. And the general consensus on this site is about 1000 rounds for a 300 RUM.

I saw that but, barrels will eventually wear out if shot enough and with hot loads faster so IMHO that's not really an answer but, an opinion. It may take 2k, 10k 100k but eventually the barrel will wear out. Coming from an experienced gunsmith I'm just curious at which point the barrel will eventually wear out. If no one's shot one enough to wear it out then the answer is IDK.

Re: Barrell Life 338 rum vs 300 rum

JWP745, How much personal experience do you have with these cartridges you mention? I have shot the 338-300 and the 338 ultramag extensively over a chronograph at long range targets. There is not a 100fps difference on average between them. They are so close it really just depends on the individual barrel. I have seen either outshoot the other. With the small amount of extra case capacity the 338-300 should get slightly more velocity but it is so negligible it is a wash between the two. If velocity is your objective then get a 338-378 weatherby which will outshoot either of these by close to 200 fps. My 340 wby accuracy load is 86 grains of powder. My 338-378 accuracy load is 132 grains of powder. On average there is about 275 fps difference between the two with equivalent length barrels. My accuracy loads with the 338 and 338-300 ultramag vary 3-4 grains of powder. Think about it.

Chas1, As I stated, The two 338's have considerably more barrel life than the 300 ultramag. The two 338's would be about equal. You can not put a number on how many rounds to wear it out because there are to many other factors involved from barrel manufacturer to the type loads shot in it and a thousand other things. The average shooter will not wear out a 338 ultramag barrel. Hogg wanted to know a comparison, he got the answer.
