Re: Barrell Life 338 rum vs 300 rum

Robster, Good point, thanks. What kinda action is a pretty broad question which will get very differing responses. It might be helpful to elaborate a little ie-how much do you want to spend, repeater or not, manufacturer viability etc.
A Remington 700 action worked over by a quality smith is a good choice or you could go custom but, can get pricey.

The average shooter will not wear out a 338 ultramag barrel. Hogg wanted to know a comparison, he got the answer.
+1, you scared me for a minute there. I agree the average shooter probably will not wear out a 338 rum barrel.

Re: Barrell Life 338 rum vs 300 rum

I had an 11 twist 3 groove Lilja in 300 RUM and I put close to 2500 rounds through it. I know that sounds high and I'm not saying I didn't lose ANY accuracy but it still shot well when I sold it. You couldn't see that much erosion at the throat? It surprised me.....Rich

Rich, that sounds incredible. What kind of loads were you shooting through it and did you give it any treatments?

Re: Barrell Life 338 rum vs 300 rum

Ya, if someone had told me that I would have questioned their math! I was shooting primarily my own bullets, with H-870 and retumbo as the primary powders. The barrel was never hot and I kept it pretty clean. No special treatment except Liljas recommended break in. The rifle shot 1/2-5/8 groups in the beginning and about 3/4" when I sold it. Go figure? I know the 3 groovers are better for wear, but that's a lot from what I've heard.....Rich

Ditto. But I'm sure jwp475 has spent alot more time shooting than I have. LTLR, you have alot of experience, no doubt, and I respect that, but your continued characterizations of the 338's just don't seem to jive with what many others find.

Even Shawn's recent story of his buddy shooting a +P version of the EDGE vs. the EDGE at very long range shows what a few extra fps due to extra hp of a large case can mean. Case size matters, coupled with the correct barrel, just like cubic inches matter in an engine. Yet, you repeatedly seem to indicate that case size doesn't really matter much.

I see your numbers and your experience and realize that my experience is very small compared to yours, but I just don't see too many other folks making the same .338 comparisons that you do. Interesting...

I do see that in your posts in this thread that you give the big Weatherby quite a boost over the RUM and EDGE--that's more than I recall you giving it in the past. I'm just trying to learn here.

Not an expert here, just a big fan and values the resident SMEs and their experiences.

I too agree with the quote above.

AJ Peacock came up in water capacity (in grains) on the following cases for comparison:

338 Allen Mag TTI Brass 172gr (Jamison Brass is 171gr)
338 Edge Remington Brass 118gr
338-378 137gr
338 Rum 111gr
340 WBY 100gr

Below is a nice exchange of info from resident SMEs in the forum that is a very interesting and is a good read, esp. on Kirby and LV velocity discussion:

fastest 338 caliber?Build advice?
