Want to start a build..

[xtrema44]

Ok I have Remington 700 lss in 7mm RUM.. After two surgeries on my shoulder I can't shoot it unless I put a break on it.. My question is since I won't be using it for awhile I want to rebuild it.
What are your guys opinion on a caliber I loved my 7RUM but I herd of this 7RUM XL??? I don't know much about it? Yes and the Gunwerks 7mm LRM which I don't understand why it has better BC then both the STW and RUM?? That another question for you guys? I think I want to stay with a big 7 because I have 300rum.. So what is a good big 7 for long range hunting or even your favorite big 7???

As far as big 7's, you are on the right track. I am not sure what you are referring to on the BC as that is up to the bullet you choose, not the caliber. Within the 7's, the RUM will be the fastest, followed by the LRM and STW. A 7 dakota would be another one in that range as well.

I'm content with my 7RemMags

 

[MontanaRifleman]

Hard to understand this... You had surgery so you want to rebarrel your 7 RUM because it kicks too hard... and want to rebarrel to another hard kicking magnum... and you want to stay with a big 7 because you already have a 300 RUM???

Get a brake. Nothing wrong with them that ear plugs can't cure.

How about a 7SAUM. Guys are killing big game including bears and elk at long range. Most are using either 180 or 168 Berger bullets.

From a guy who's had more orthopedic work than the 6 million dollar man I say go with the STW. You get neck and neck performance with the Rum at dramatically reduced muzzle blast and recoil. Put a good brake on like the Snown Mountain Rifles Muzzle brake on an 8lbs rig and you will be in love.

Another vote for the 7mm STW.

I am facing the same issues with one neck surgery last year and possibly another this year. It still effects my shoulder and I cannot shoot the large magnums anymore and even with a brake it leaves me hurting for a couple days.

IMO go with a 8 lb 7 SAUM and a removable brake. You can spend time on the bench and take it off to confirm zero's/loads etc and then hunt with it with or without the brake, otherwise you might as well stay with the RUM and just try to brake it. LRM/STW will not be much different in comparable weight guns as they and the RUM really run neck and neck in MV and recoil.

The SAUM will take the 180 to 2950, and couple guys locally are shooting that load to 1500. It also has proven to be easy to load, softer recoil, which is really what you are looking for it sounds like.

I am sitting on a 7mm #4 benchmark barrel and brake, Lawton magnum LA and a special manners stock that weights 1 lb 14 oz, as I was going to do the LRM but pretty sure that is out the door when I started looking at the amount of recoil etc compared to others.

I have got a 7.5 lb 300 WSM that hammers with 168 TTSXs that I am going to try to stay with for now and might drop the bullet to a 150 if I have to. Might even have to pull out that 6.5x47 or my 7-08

I went back to Len's recoil spreadsheet he has here and plugged in the SAUM, LRM/STW/RUM info.

Basically you have almost 1/3 less recoil with the SAUM compared to those three with equal 8.5 lb guns shooting the 162 in the SAUM vs the 180s in the larger 3.

The SAUM is at 3000 with the 168 with 62 grains of powder and the others are all at 3100 with 180s and 72 grains of powder. Not apples to apples, but you are not looking for another apple like the RUM.

 

[Derek M.]

Is there a remarkable difference in a 7SAUM and a 280AI? I ask because there seems to be continued recommendations for the saum but isn't brass scarce?

Correction. There's a dramatic difference in recoil with the STW vs Rum. Look at max powder charges for the two with similar bullets. You are using about 10% more with the Rum producing significantly more recoil and muzzle blast. I've shot both and shot the 7mm Mag for over thirty years before moving to the STW and with a decent brake like the SMR which I have on my Sharpshooter Winchester it's a ***** cat. My brother's 14yo boy who weighs 118lbs (wrestling weight) absolutely loves it and drives it like a pro. Recoil with the 160's is nothing and 140's are barely noticeable.

I run the 7mm Dakota with Matrix 190's at 3041 FPS and recoil with a break is very mild. Brass is easy to get, even though it's spendy. Overall I'm very happy with the performance.

Chris I just went to your website and did not see .277 as a caliber option but a note that said to contact and see what you can do. I'm not shy about trying new barrels and I've been doing some reading about yours on this website as well as others. So, what do you tell someone who is looking for a caliber not listed on your website? My most common cals are 6.5, 277, 7mm, 30, and 338.

 

[WildRose]

Derek he's not exactly new to the business. I have a friend that builds nothing but precision LR rifles and has built over a dozen of them with Chris' barrels.

You won't be disappointed.
