after ton's of reading and comparing component cost I'm thinking my next barrel will be of the 6mm flavor. I currently have one of Jim's .308 barrels but I've been shooting beyond 800yds more frequently and want to push it 1200+, with a 18.5" .308 thats not really happening (yes I did try the 208's this last time out but also looking for a more economic option that is better in the wind) a 26-28" 6mm variant would be a no brainer...but I'm waiting for approval for a F1 suppressor so that length is out of the picture (I plan to shoot suppressed more than not) The 6brx has really caught my attention but I have found no info for one with less than a 26" tube. reason I like this cartridge most is I already stock popular powders for it and brass is rumored to last forever. I will most likely shoot 105 amax's exclusively no matter which cartridge I choose and would have it throated accordingly. I'd like to end up no more than 22" but 20" would be ideal. The second cost effective solution seems to be a fast twist .243 throated for 105's, the other is a .243ai (more so for brass and throat life) but according to quickload those options gain very little in the velocity department (with a 20-22" barrel that is) over the 6brx which would translate into less barrel life, and 10+gr of powder per shot more, not to mention yet another powder to keep on the shelf.

I will say I was sold on a 6.5 untill I seen the price difference of the bullets. .22 vs .31 cents at todays prices (105 amax vs 140 eld-m)

Thanks for reading my long post.

243 30* or 260 30* looks good to me. So does the Creedmoor in 6 or 6.5

243 30' thats the 6mm super LR right? looked at that one briefly also, there all so close it seems, 6xc, 6x47L, ect... have not heard of a 260 30'? the creedmoor's do seam appealing but I hear mixed stories on the brass. up untill this weekend I was dead set on a 6.5 then I seen how cheap the 105 amax is and how close it performs. I like the option of the 115 dtac's if I really wanted to push it. and those are around same price as the 140 hornady's

Ok well after more reading and seeing some rediculous shots out of 6brx handguns I think the better question is, Is there any reason not to run a 6brx? and how short is too short? seen a video with a guy getting just under 2950 with 105 bergers out of a 18" handgun and banging steel at a mile! granted yes thats extreme and subsonic long before but still shines hope on the concept i'm after. less expensive fun that will reach out a decent distance. with an estimated brass life of 20 reloads using lapua brass, 33gr varget, and 105 amax's I calculated 40 cents a shot for a little round that will reach to 1200 with ease(on paper that is)
