.338 Edge AI?

[RichCoyle]

Anyone know how the .338 Edge and .338 Edge AI compare? Is there any gain in velocity? What are their velocities with a 250 grain bullet?

I don't know but given that you can make Edge cartridges by necking up 300 RUM (or buy ADG), I wouldn't consider it. Fireforming is too much of a waste of time, components, and barrel life.

I'm just got my edge together so I'm tagging in

That's your opinion and you most welcome to it but as I have a bunch of AI stuff it's well worth it to me

So did you get an Edge or an AI?

I've got an Edge but I'll AI it in a skinny minute

Why not just +p the edge? Not sure how much more you'll get out of it by making it and AI. I'm hitting close to 2900FPS with a 300 grain Berger OTM

Barrel length?

From what I've experienced it's about like AI ing any other cartridge, 50-100fps gain at equal pressures. I ran 102gr of N570 out of a 29" Brux at 2980fps with Bertram brass in my 338EDGE AI with the 300gr Hybrid, 2950 with H1000.
250 berger at 3150 w/h1000 and I believe it ran just under 3250fps with n570.

Barrel length?

27"

Barrel length?

Nice

Doing the numbers on capacity gain, it appears the max velocity gain you could probably produce is about 50-75fps…even with US869 which fits the best.
If I am to AI a cartridge, there must be 200fps gain or mechanical feature additions to make it doable.
The RUM is not a cartridge I would bother doing, in any calibre.

Cheers.

I run 250 grain SMK's at 3150 out my 28@ PacNor barreled edge. That's with Norma 300 rum brass and a pile of H1000. I did take it to pressure just over 3200 but was loosing primer pockets. No clue about an AI version

This is about 50fps, maybe up to 75fps, more than my 30" barrel running a +P 338 Edge. I could only get the 300g pills at a max of 2950fps…never shot anything lighter than 265g. Was hoping to beat 3,000fps with 300's, but no.

Cheers.
