If I were doing it now, I'd use 6 GT brass as a starting point. It's pretty easy to find and it's really good quality. Not that the 6.5x47 Lapua brass was hard to get or bad quality, but the 6.5x47 cases had to be formed, then inside neck reamed and/or outside turned. The GT case shouldn't need...

It’s been a few years so I could be off on some of my specs: - 18” 1-8” twist barrel from AR Performance - Rifle length gas system - adjustable gas block - H2 buffer The 270 AR was a cut down 6.5x47 Lapua case. By the time you were done, it was essentially a 270 Dasher, but with a slightly...

A 6 Dasher sounds perfect for that sort of work. I didn't have any feeding issues with the 6.5 BRX the very similar 270 AR using the notched PRI 6.8 SPC mags that Cavity Back Bullets sells. I actually thought feeding would be the biggest issue with that project, but they both ran 100% once the...

I had a few of those in a 6.5x338 RUM wildcat using US869 and CCI 250s. It got my attention pretty fast! I switched to Fed 215s and never had another issue.

Will the 458 SOCOM and 450 Bushmaster bolts hold up to the higher pressures? That was a big debate when I had the .473 bolt face rounds. I was using the ARP bolt/extension combos. I remember there being problems with the SOCOM bolts, and Grendel bolts, failing when you got over 35K PSI. I...

It sounds like an ignition issue. US869 can be a hard powder to ignite, which might be why you saw the problem after switching to standard primers instead of magnum primers.

I would go with the Dasher if you have a source for the bolt and barrel extension. I didn’t think anyone was still making a .473 bolt for the small frame ARs I had a 6.5 BRX and a 270 AR built on AR 15 frames for a while and they were pretty fun. The BRX just wouldn’t shoot better than .75 MOA...

I used the Montana Bullet Works 315gr WLN-GC bullet in 2 different 444 Marlins with good results. These days I’d look at some of the Cutting Edge options.

Looks great! I had a 270 RUM for a while and it was a lot of fun. I had mine before the 170 Berger was release, so there weren’t a lot of really good high BC options to pick from. I found a happy compromise with a 140gr BT at about 3475 fps using US869. Accuracy hovered around .5 MOA, so it...

That’s where I got the idea for the name! I had a 7#, 458 Win Mag for a while that I only shot 500gr bullets out of. I’m still convinced that one gave me a few concussions. 😂

You need to pick up some of the Peterson belted mag basic brass. Just think of pushing that 450 Ackley to 70K psi!

I had 450 Ackley pass through my hands a few years ago and it was a ton of fun. I don't think it did anything that a 458 Lott couldn't do, but it was so much cooler looking! I shot a handful of rabbits using reduced loads with Trail Boss and cast bullets just for fun, but the full power stuff...

I’m anxious to see how the 36 Nosler works for you. It’s one of the only bore diameters I’ve never played with. It won’t do anything that a 375 Ruger can’t do, it’ll just do it with more style!

I’ve had good luck with the Sierra 180 SMK loaded to 2.850”. I’ve only used it for targets, but I’m very happy with how well it shoots.

Sorry, I should have been more specific. A short barreled (18-20”) 338 Win Mag would be in the same performance range as a standard length (24”) 338/06 with similar weight bullets. That’s just based on my experience with both chamberings. I found those two to only be about 150 fps apart from...
