My 300ss (Sherman Short) Ruger M77

[odoylerules]

I finally got my 300ss up and running. I wanted to rebuild my old Ruger M77 (sentimental value). It was the first rifle I ever bought chambered in 7mm mag, and I killed 2 elk with it many many years ago. The Ruger internal box is tiny, like 3.4" which really limits what cartridges I could run. The 300ss was perfect!
My smith squared the entire action and bedded the original boat paddle stock, which I really wanted to keep.
It has a Bartlein barrel, 26" 10tw 3b contour.
Bare rifle weighs sub 7lbs. Launches Berger 215's at 2870fps. During testing I got close to 3000fps but best accuracy was sub 2900fps.
As you can see it's a TACK DRIVER!
1 hole groups at 100 yards.

WOW!! Ill say its a tack driver! Nice build and good to see how that Ruger worked out. This is typical of how the 300 shoots with a good load. Can anyone spell COMPETITION
Keep the data coming

Very Cool! I like that you have elected to keep the stock!
I started shooting Ruger's when I was just still in High School 30+ yrs ago, the first rifle I bought was an old tang safely 30.06 and when they came out with the MkII I sold and bought another 30.06 in the Mk II, which I still have today!

I would love to upgrade the barrel on it someday!

My load is 65.2 grains of RE26, Berger 215 going 2870fps. SD 4.2.
Here's the load development at 622 yards. 2.25" group.
Took that back to 100 and shot a ragged hole!!
Thank you Richard Sherman! (Elkaholic)

Short and fat is where its at! Shocking performance from 65 grains of powder and 215 grain bullet. Before it's all said and done I will have the 6.5 sst,7sst,and the 300ss switch barrel tikka. Great job rich!

I'm basically getting 300 win mag performance from a short action cartridge!

Looks good! Next mod would be having your smith drill and tap the receiver so you can run a pic rail and normal rings. EGW makes a base for it, that requires drilling and tapping, but once done, you're good to go.

I've had M77 MKII's for over 20 years, and I've had plenty of issues with the proprietary rings. Plus, it really limits your options.
