Model 7 - Saum rebarrel.

[Prairiekid]

I am wondering if a Model 7 in 300 saum would be a good candidate for a rebarrel to 7 saum. Obviously, it can be done. My question is for 140 grain - 160 grain bullets. What I am wondering is there a disadvantage to this action over other commonly found actions?

700's are one of the more common guns to modify. I assume the action you have is a short which will be fine for that size of bullet. If you went up to 175's or bigger I would suggest a longer action but you will be fine with the 140-160's.

or go with a 7ss to shoot 180s in a SA.

The 7ss is intriguing. I guess the saum seems more popular. I don't really shoot long range, 500 yards tops. I am currently using a 7mm-08 and it would be nice to have a second rifle that I can stretch out and have a bit more energy.

I don't own a Model 7, but I see them for sale in 300 Saum and it seemed like a decent option to rebarrel one of those.

There are no disadvantages with that Model Seven action for what you want to do.

I have a 7Saum in a short action running 162 ELDX, can absolutely work.

 

[Str8shtr]

I think you'd be fine in a sa with up to 160ishgr bullets which are more than adequate for up to 500yds. I'm not sure what a used model 7 costs but it might be worth it to just buy a custom action.

I have been considering a custom action as well. I'm not sure what the best options available in Canada really are. That is always a factor up here.

I have a Model 7 in both 300 & 7 Saum. Love that 7mm.
I plan to fin another Mod 7 and rebarrel to 6.5 Saum just for the fun of it I guess.

I prefer the model 7 over the 700 SA. It is actually 1/2” shorter! And has a bigger port for longer bullets. Only draw back is less after market components. Harder to change the mag box for the longer bullets

Are your model 7's all factory camberings?

 

[wildwilderness]

I have a 308win and a 300 SAUM in a model 7. Been thinking of making a 35 SAUM on a M7 for a suppressed bear over bait rifle...

 

[N2TRKYS]

I have Model Sevens in 7 SAUM, 7-08, and 308. They seem to be the perfect little rifles for me.

Yes. Have change stocks and triggers on them though.

I have a model 700 titanium short action in 300 saum, it loves the 150 ttsx and 165 accubonds, shoots my handloads for those sub MOA with a christensen arms carbon barrel. Can't speak for the model 7 though.

Yes, there is a disadvantage to stuffing a 7 SAUM into 2.83" mag length even with lighter bullets when compared to something that allows a longer COAL. Doesn't mean it cant work well but it is a disadvantage if you want better ballistics.

What do you mean by better ballistics?

With more mag length you can set up chamber and ammo to run faster velocities at same pressure.

I believe he means that you can’t run the the high b.c. bullets (180+ grains) without seating them deep in the case which eats up powder capacity.

Or plenty of low BC bullets for that matter. 2.83” coal is short for a SAUM even without the long and heavies.
