REQUIREMENTS:

NO BARREL BURNER / NO "MAKING" BRASS / OBTAINABLE RELOADING SUPPLIES / PREFER SOME FACTORY AMMO AVAILABILITY but NOT A DEAL KILLER:

I've got a Tikka T3 300WM that is in the safe collecting dust. I just don't shoot it....its smaller brother Tikka 270 took its place for hunting here in Colorado. SO.....looking at doing something with it in probably a KRG Bravo stock with LRI prefit barrel. Pick up a Cameraland Bushnell DMRII / Kestrel deal for optics and ballistics. Its duty will be paper punching and some random hunting with it (allthough the 270 will do most of that work). Some long range coyote work would be fun, and some mile shot attempts as well. My reloading requirements are that brass is readily available and some off the shelf ammo would be nice to get started on it.

I initially thought 6.5 PRC since that is the new thing it seems and theres some nice off the shelf ammo available. I have 16# of Retumbo to hand roll it as well. Then I look up and see I have around 16# of H4350 and a set of new in the box Whidden 6.5CM dies for some reason. Major part is the 6.5CM would require a new bolt which seems pricey and a mile shot is pushing it with the Creed.

Some other folks recommended a 7WSM and several other 7mm calibers but I don't think brass is easily obtained. Thanks

7 saum is pretty amazing.
It will drop pretty much anything, does excellent at a mile and recoil is mild.

ADG makes excellent brass for it.

Sammi chamber really likes about 3.0-3.1 oal with the 180-190’s and that makes more room for H1000 and retumbo than running them in my short action.
 
That 7 SAUM peaks my interest for sure. How is Retumbo doing in that cartridge?

Are you guys suggesting that over the 6.5 PRC for the hunting reason? Im not as concerned with animal knockdown on this rifle as the 270 will fullfill most of that roll (at reasonable distance)

Cant seem to find any 7 SAUM ADG brass. I DO NOT want to build a rifle that will require unobtanium type reloading material. I have Retumbo on the shelf but once thats gone....?
 
If I were to re-barrel my Tikka T3x from 7mm RemMag I'd probably do 7 SAUM. The 3.41" OAL restriction of the bottom of the action inlet would be a deciding factor.

Unless you're like me and you took hours to hand file a notch in the bottom of the action to allow OAL of up to 3.63" with AICS mags ?

but even then 3.63" doesn't get you a 300PRC
 
I really like what Im reading about the 7 SAUM. Just dont like what Im seeing on hit/miss brass but seems manageable. Anything else I should know about the round? What kinda barrel life?
you could do a 7 Max which is same parent brass but faster and more better

Seems the Sherman rounds might be kinda heading down the wildcatting rat hole. Not ready to jump into that. This is from my short reading about it.

not much different than SAUM in reality

ADG headstamped and formed brass
dies are same
powder same
bullets same

unless you need to shoot factory ammo. which is scarce for a SAUM anyways. i'd be shooting ADG brass only so that point is kinda moot

So say 7 SAUM it is. Whats your take between Norma and ADG brass quality?
My ADG brass has been excellent.
Im almost at five loadings and it’s time to anneal.
Primer pocket are still felling good even with Winchester primers
How is Retumbo acting in the 7 SAUM?

retumbo is usable since you’re not running a short action, same with H1000 and 7977.
R26 is awesome in it and a savior for my short action.
 
Keep it coming guys. GREAT INFO!

Ive talked to Chad at LRI already about a barrel for my action and Im sure the 7 SAUM wont be an issue. I think Im going to grab my optic first and get that big cost out of the way. Im having a hard time passing on the Cameraland Bushnell DMRII / Kestrel deal for $1049 since I need an upgraded Kestrel anyway. THEN I kinda want the GAP Bushnell XRSII / Kestrel deal for $1699. Just not sure the DMRII to XRSII upgrade is worth $650 bucks. With the further range of the 7 SAUM maybe it is.....I dont know.
 
Youre correct in that the actions are all the same "long" action length. But the krg uses AICS or CTR mags. CTR mags are only short action calibers, and the aics Mag well is for short action

The step up in glass quality is worth the extra $$ for the XRSII. Buy once, cry once applies here.
