Jon it looks like its only you and Bryan Litz who shoot 338 edge. All the cool kids are shooing 338LM. :)

Nice matching set though. Now you need to add a 22LR trainer to the set!!!
 
Picture of mine, in the temporary stock and a quick picture of one of the stocks I am working on with a buddy.


and the stock

John172. Is your chamber throated long enough to hang the bullet out like that? Mine is a McGowen pre fit and my OAL is 3.91 just touching the lands with 300 bergers (elite hunter)
What brass are you planning on running? I just ditched all my 2x fired federal, the primer pockets are pooched already, no pressure signs. Switch to a bunch of necked up Remington 7RUM brass, fired the first of it yesterday, same load data, same velocities. Going to fire the same brass a few times to see how long it holds up.

28" barrel 300 berger at 2770 fps. 89.6 grains of IMR 7977, not compressed.

Meh Lapua, nothing the edge can't do. Only problem now is the Lapua brass is better, easier to get, and probably less expensive.

If I was going to do a boomer all over again. I'd probably stick with a 30 cal of some form. 300 Norma or the like.

Try the Bertram brass. Comes fully formed. We got in some cases for the build we are doing right now. Defiance Deviant Hunter, Benchmark spiral fluted barrel, Mcmillan gamescout. Should be a decent sheep rifle when its done.

What kind of ungodly prices are we looking at for Bertram brass? I have read mixed reviews about some of their stuff. Mind it was older brass and old reviews I dug up on the internet? Any experience shooting it yet?
I personally don't mind running the 300 RUM brass through the die. But regardless of the work I want it to last more than 2 or 3 firings. Time will tell with this Remington brass I have at the moment.
Too bad Brownells decided they won't ship Norma RUM brass to Canada. I messaged a store we aren't allowed to speak about on here about some Norma brass. It was close to double the US price even after the exchange.

I figured as much, just the same way I was trying to get a rise out of the Lapua guys. Same crap, different shape.
 
I have new Bertram brass, don't ask about price.
Kiwi Greg from terminator brakes swears by remington.

My throat is super long, 4.040" is just touching lands with berger 300's which places the base right at the neck shoulder junction.
Getting full case capacity I should get 2850 fps

I have thought about getting a throater and sticking the barrel in my lathe to stretch it out a bit.
I did a seating depth test today, as I was getting sporadic flyers and inconsistent groups when I was about.010" off. At .020" it settled right down with 3 rounds going literally into the same hole, 4th one just outside of that hole and the 5th round opened it up to about .7 moa. Getting sub 10 fps SD's. Works for me, as long as the brass will stay alive any ways.

I bought 6.5mm throated for my 260 to use 140 grain bullets but then left it alone because it shoots so well with 123's as is.
If it ain't broke...

Kiwi Greg from terminator brakes suggested I start with 0.008" jump which I thought was short, if 0.010" was so erratic for you I'm going to plan my original 0.020" starting jump.
 
The Bertram ran about $4.90 all said an done landed in Edmonton. If you need it, you can check with Gary at Bighorn Sales. He was our source on it. Haven't had a chance to fire it. We just sourced it for a customer of ours, but we built Geno's at MDT as well and he has started shooting it. Seems like nice brass, well annealled.

My partner runs the Bertram 338 Cheytac brass and it has held up pretty good. MUCH better than the Jamesion.

This is also a picture thread, don't be shy ; )
 
Drop box doesn't embed videos. Ought to have known.
Will put youtube video in as soon as it's uploaded.

338 Edge, 300 Berger elite hunters.
1110M

I added an extra 0.1 mil of elevation before I started filming. Probably shouldn't have done that as I missed a couple rounds barely over the shoulders of the plate.
In the spotter's defense. He was watching through the camera screen, or naked eye.... With dead Peltor batteries

Awesome video! You really caught the swirl nicely.
Were you holding center mass?

I'm finding it hard to believe there's no other 338 edge guys on cgn!

Yah you'd think there would be a few more EDGE's out there.
I was holding center mass. The target was partially obscured by grass in front of the shooting line.
That coupled with my terrible shooting and a bit too much elevation dialed on.

Hoping to out a serious hammer down on a few long range coyotes this fall/ winter.
 
I will be joining the 338 EDGE club this winter. My 300 RUM is all but wore out so time to rebarrel. Barrel is in hand and ready to go. Was thinking of going with the T4 brake. Anyone tried one and if so does it do a good job of reducing the recoil? Also do any of you guys shoot the Hornady 285 ELD?

Any searching I've done always comes back to the T4 being the most efficient brake available, anyone please feel free to correct me because I want the best I can get and am planning the T4. Getting yours from rangetech.ca?

What action are you building on? What barrel is it?
 
My Action is a trued 700. Barrel is a Rock 30" 1-10 fluted AMU contour. Yes I was planning on ordering through rangetech. I have accumulated all the parts for this over the last 1.5 yrs. Really don't shoot my 300 RUM much anymore (has about 1600 rds through it) and figured a EDGE BUILD would be fairly economical.
 
I have an atrs built 338edge ai. 30" rock creek barrel, trued 700 action, mcm a5. It seen about 550 rounds now, plenty of horsepower. If I was going to do it again I would like to go to something like a dta srs, or the defensive edge bullpup style. A 30" barrel and 4" brake makes for a pretty long rifle.
Anyone shot the Chinchaga 300 or 325gr? They look pretty impressive.
 
Not a real good picture, but my .338 Edge is a Defensive Edge Canyon rifle. Mine is on a Bat repeater action, 30" Hart Fluted barrel, Jewel trigger and HS Precision stock. In this picture it is wearing a 8.5-25 Mark 4, it is currently fitted with a Nightforce NXS.
