Anyone here have an Ackley Improved gun? I'm building a 338-06 AI and was wondering how you fireformed your brass. I've read of a few different techniques, just want to see what you have tried and how well it worked.

Going with 28 or 40 degree shoulder? I've loaded for '06&.30-30AI but never formed them. John Barnses has a method using cream of wheat(Really!) that may help you out Au338.
Only hits count.

I used to have a custom 7mmAI (7mmMauser blown out) I fireformed 7mmMauser loaded ammo. Handloaded for the dang gun, never got it to shoot under 3" and sold it. Pity, cause it was a beautiful rifle.
I've spent most of the money I've made in my lifetime on hunting and fishing. The rest I just wasted.....

Waste of time imo, if you want faster or more power just step up to the next size or either move into the weatherby'.
If I agreed with you, we'd both be wrong.

I've read of the cream of wheat method. Some suggest running the necks over a tapered expander one caliber larger, the resizing the necks, but leaving the base of the necks unsized. This is supposed to give a tighter chamber fit when fireforming the brass. Has anyone tried this? I may try this with the COW method.

Buddy of mine used the cow method and had good results with fire forming. Make it easy on yourself and just build a 338 win mag and be done.

Just anneal and shoot it. You'll not split as many if you anneal first.

It isn't but if you want to do a 338-06 I'd probably go AI just "because". I mean why not. There is really no case against it in that particular caliber if you are going with it regardless.

I once had a 21" Contender barrel in 30-30 rechambered to AI. Jimmy McCollough in Selma had a reamer and did it for me. All I ever did to make the brass was to just load a standard 30-30 load and shoot it.
I hunted with it using 150g bullets at 2560 fps, so I wouldn't say it was a waste of time. No way to get that velocity in that barrel with regular 30-30.
All the labor of man is for his mouth, and yet the appetite is not filled.

Anyone done a 260AI? The claims of 2900 plus with 140s seems interesting to me. There are a lot of claims about big velocity gains with Improved cartridges on the Internet. Most of these are probably loaded to dangerous pressure levels. Cases with little body taper tend to not display the typical high pressure symptoms (flattened primers, extractor marks, etc,) so people assume their loads are safe when they don't see these signs. There are basic formulas you can use to determine safe velocity levels when comparing standard and A.I. cartridges based upon added case capacity. I only want to A.I. my 338-06 for the novelty. The velocity gain will be negligible over standard 338-06. Probably about 50 fps will be the most I can gain in velocity.

Don't shoot it much but it's a great round. I wondered if you still had it; glad to hear that you do. I have often regretted selling it, so please give me a chance at it if you ever wanna get rid of it. I have no personal experience with it, but 2900 from a .260 AI doesn't seem to me like it would be at all difficult. It's not hard to beat 2900 with a 150g bullet in a regular .308, and you are talking about more powder capacity in the .260 AI. I realize the smaller diameter of the barrel is gonna reduce efficiency, but it still sounds possible to me. I could be wrong.
