Home Forums Hunting & Shooting Long Range Hunting The Big 7's......Which One?

I have run a ton of them and when it all boils down I stuck with the Saum.

I have put together several of them in various configurations. I finally settled on a 22" semi custom if you have questions pm me.

My rifle is pretty heavy with a light Palma 9 twist Bartlein plus a brake. Recoil is pretty much nonexistent even shooting the heaviest bullet available. I think the A3-5 will be awesome when it's here. The plastic factory stock sucks but it still shoots well in it. I'll know more when it's totally the way I want it.

I made an error here; meant to write 2880 with the R25 load.

My Mashburn is just a M700 on a HTG with a No3 Chanlynn.
Not a flyweight by any means but not as heavy as yours.
Mine is a 1-10 twisted.
I run the 168g Berger Classic with H1000.
Dang thing almost shoots with my bench guns.
I get a kick out of you running 195s in the MSM.

You should try them. I'll be shooting some matches with it for sure when it lives in the right stock. Seems like it'd be perfect for some 1000 yard crows!

I thought i need a faster than 1-10 for the 195.

You do. Why did you go 10 anyway?

I had ordered the two barrels for a project I started in 1989.And never finished.The barrels laid around for years before I got back to it. ..never really though about running anything that heavy for deer.Im a 140g ballistic tip for deer, kinda guy.
My Mashburn was kind of a afterthought parts laying around kinda gun so I ran the parts I had..

I'm stabilizing the 195 in my 9.5" twist 7WSM, though it's not ideal by any means...

I to am interested in the 7mm saum. I shoot 140, 145 and 150grain from my 7mm Weatherby but it doesn’t stabilize heavier bullet well. does anyone have experience with the older Weatherby barrels and if so have they been able to find any bullets above 150 grain to shoot well. Another question does the seven saum shoot a heavier bullet well or is it a better lite bullet or target caliber?

This. I like Ballistic tips too.

It's the stupid 1:10" twist that Wby put on them that is the problem. I have a MkV 7mm Wby. It shoots 160gr Barnes well, but I shot a bunch of Federal-loaded 160gr copper tipped bullets out of it, and, at 100 yds, they all were making oval holes in the target.

I bought my 7mm Wby in ‘81 and it shoots 175 gr Partitions very well with IMR 7828.

The simple answer here is to rebarrel the 7 Bee with something in the same profile but a 1:8 twist of so. You should be able to stabilize anything up to 200 gr or so (if such is made).

I've got both a 7 Mag in an 1885 Single Shot and a first gen 700 Ti in 7 SAUM. That SAUM shoots 140 gr. TTSX's damn near in the same hole. It's my "go to" rifle.

I shoot only the 197 SMK's in mine and it does very well.

Speaking of old 7 threads..........

Interesting. Is that a 1:10" twist?

I would if it were a go-to rifle. I just replaced it with two 1:8" twist 6.5-300 Wbys, and I passed the 7mm Wby on to my 17-yr-old son. It shoots the 140gr and 160gr Barnes really well, which should suit him for anything for which he's going to need it for a while. Incidentally, when they started going out of production, I loaded up on some CorBon loaded 160gr TSXs. CorBon ammo, perhaps coincidentally, always shoots lights out in my Wbys, and they're usually loaded hot. Their loading launches the 160gr TSXs at 3,240 fps out of the MkV I gave my son. I wish they loaded something for my 6.5-300.

I’ve never measured it but it’s whatever the factory used at that time. That’s why I mentioned the time frame. BTW it was Japanese made Mk V that I bought while I was stationed in Japan.
