Home Forums Hunting & Shooting Hunting Rifles Nice Score on a BDL SS 300 SAUM

Why change anything ? I agree with the others that say leave it as is. There is lots of brass around at this point and you will burn less powder and get better barrel life than a 300 WSM at least in theory. I have a rem 700 sendero in 300 saum and it has been great, it shoots 150 grain bergers 180 gr accubond, partions and barnes TTSX very well. I use RL 15 for the lighter bullets and H-4350 and RL 19 for the 180's. My current hunting load is the 180 grain TTSX at pretty close to 300 win mag speeds. With this bullet seated to a LOA of 2.825 ( the max length that will fit in the mag and nowhere near the lands) am am getting three shot groups between .250 and .500 with H-4350. I am using forester bench rest dies and getting .001 or less runout at the case necks which really surprised me as this is better that i get with my 22 ppc .

goose,

I bought a 7SAUM with the very same intentions that you had with the 300SAUM. Ummmm, then I shot it. A new handle and a GreTan firing pin assembly is all it needed for upgrades in my eyes. It's quickly become one of my favorite deer rifles.

Goose - don't touch the rifle. Shoot it first, then get back to us.

I've been shooting a 30/7 SAUM for ~ 5 years. The 30 SAUM will get you 2950 with a 180 and will break 3000 with ease with a 165 of any flavor. Have a serious look at a ballistic chart to see what you are really gaining by going WSM. Not much.

You could always give Stocky's a ring, order a B/C Ti stock and be in ~ 7.5 lbs and out another $200. Add Talley's and a Leupie of some flavor and your set for the next 40-50 years or so.

I know a bull last week that hates the 30 SAUM...........

BTW: if you're feeling the need for more speed, try Re 17. I broke 3000 ft/sec with a 180 Partition and 61.5 grains (max is supposedly 63.0). I do believe the Re 17 data is a bit optimistic as far as pressures are concerned.

The early R-17 data reminds me of the early Varget data and the early Magpro data. All of which I thought were either optimistic with velocity and/or powder charges.

The only reason I would consider changing it to the WSM is so I don't have to stock up on brass now. SAUM brass will probably go exstinct within 5 years or so. The WSM, I think not.

I'm sold guys! This thing will get stock and a trigger at the most. Dies and brass are on the way. When I return from elk hunting, I will get to the loading bench. I will make this my primary spring bear gun for now. This way, it has an assignment.

Well I couldn't stand it. I had to go shoot this thing even if it is freezing outside. I loded up some 165 Accubonds over H-414 and put it through the works. These were just short enough OAL to fit in the magazine and cycled flawlessly. This was more for my interest than it was a serious barrel break-in or group shooting session. The best groups were around 1.75" for 5 shots, but it had tendencies to put 3 into one hole. The first 3 were just over and inch. This is a combination of the shooter (me) the weather, the new barrel and a one powder one seating depth load. With more round down the tube and some tweaking and this rifle will shoot. Recoil felt no different than my 280, 30-06, or 7 mag. 20 rounds from the bench was no issue at all. I could have done 20 more quite easily.

What I found most fascinating is how smooth this barrel is for a factory tube and how clean H-414 burned. My 22-250 load with this powder is plain filthy. After 20 rounds, the SAUM tube was still shiny and had no visible residue. After I got home and put the clean to it, the copper fouling was almost nonexistent. This barrel seems to show some good signs so far. I will continue to work this combo at different seating depths until I can get a good range day with favorable conditions to run some over the chrony and work some other powders and bullets if needed. I think I'm going to like this little 300 mag.

Did you think we were pulling your leg?

This croud? Never!

I still don't like the fact of gradually stocking up on brass, but it's not difficult to find at all. It's just not on every sporting goods store's shelf.

After owning and working with several WSM's, mostly 270, I instantly noticed some features of the SAUM case that I felt supported the claims of it being a better design.

1. sizes easier and smoother
2. fits in the magazine much better
3. feeds without even the slightest hangup
4. the WSM's cases get scratched up from magzine feeding I didn't find this to be true with the SAUM
5. extraction was much better with rounds in the mag compared to the WSM

I'm sure I will find some drawbacks as well, but this is just from one short 20 round fun session.

Remington's marketing messes up another one, but we already knew that!

Because you're giddy,I'll grant you a pass...........

Nothing beats a Remington 700 in any caliber.

IN THE WORLD!
