AIAE in .260 any problems ?

[Rprecision]

I was reading a good article about the 6.5's written by Zak Smith. In the article it discussed blowing primers in a AIAW in a .260 The article explained this was a problem for the military design of the AI. While the author seemed to work around the problem there was mention of not being able to run full power loads.

I am planning on a AIAE in .260, is this something to consider or rethink?

This is all new to me thanks

The primers being blown was for the 6.5x47 Lapua because it uses a small rifle primer. The 260 in an AI is problem free

As i understand it, he only had issues with remington brass. Lapua was working correctly, also with hot loads.

I believe lapua now makes .260 brass, so you wont have to form it from 243 or 308.

Not sure on the pierced primers, but i assume it's not the cartridge that is the problem. A .308 will probably do the same.

Good friend of mine had an AE in 260. Ran like a champ

You have to be a little cautious when doing load development with the 6.5mm calibers because of the larger firing pin hole, but overall we've sent out a lot of .260s that are problem free. If you're trying to load a .260 to be a 6.5x284 lite I wouldn't recommend an AI.. however you can still get a very decent .260 load.

Not the 260, but I only shoot 243 in my AIs, never had an issue. I use Lapua brass and have got other pressure signs during load development but never piercing primers, maybe a little primer flow, but I don't sweat it.

Only problem with my AE MKIII .260 is work and grad school keep me from shooting it.

I've ran 140 A-maxes above 2,900 fps in mine. Bullet 0.020" off lands with Lapua brass, CCI BR-2, H4350. Never hit pressure either.

I'm on my second AINA 260 barrel. No problems. The second barrel shoots the same loads as well as the first.

Not an exact AI gun by my Badger M2008 action with the .260 Rem. barrel on it and I've also got a .308win. barrel fitted up to the same action.

I haven't had any problems with primers/loads with the .260 Rem. Got a few hundred rounds on it now with no issues.

Later, Frank

I blew enough primers with my 6.5x47 barrel on my AW to stop using the barrel in 30 rounds. But I have had zero issues with a .243 barrel or .260 barrel, even when using some VERY hot loads.

But isn't it a known problem with the Lapua because of the small rifle primer?
