Well, you just had to go and get me started........
You could say I'm partial to the 'Roberts. I've got two. Almost three, but the third one is a .257WbyMag. But it "thinks" it's a 'Roberts too....just a tad bit of an over-achiever, though.....But because of the "disrespect" it gets, it compensates with 1/2" groups at 3,600fps with a 100gr bullet. But, it does loose a bit of penetration from the "excessive" velocity.
My first one is a Custom M98 Mauser with a 1983 E.R.Shaw barrel. It has the so called 3.0" chamber. I've hunted it hard and put it up wet a few too many times. The barrel has a healthy dose of pitting (I suspect from poor metalurgy rather than improper cleaning...its confined to a 5-6" mid section of the 22" barrel; another story for another day).
In it's day, it would shoot sub-moa for 5-shots with most any Sierra, Hornady, or Nosler bullet. Now days, it'll still shoot moa for the first 20 or so shots, and then it starts fouling badly an accuracy will fall off badly. But, it's still beautiful to look at with it's fancy grade Bishop walnut stock and deep polished blueing. It's always been about deer hunting though, so it does yeoman duty for the "Lady folks". It's had the stock shorted to a 12.5" lenght of pull for my wife and daughters. They all have killed their first deer with it. One shot kills, all !!! Rifle weighs a dimutive 7.0lbs with the Leupold scope, sling and 5rd of ammo.... I can hold it out and shoot it one-handed.
The second is a garden variety Ruger M77MkII. Nothing fancy, and had to be glass bedded, and trigger stoned to 3.5lbs to get it to shoot ~1.25-1.5moa. But like the first, it's a deer destroyer. I've taken 11 deer with it, 11 shots. It's favorite load is 38.0gr of IMR3031 @ 3,000fps under a 100gr bullet. (go figure! a warmer version of the original factory load, about 36.5gr IRCC).
Of the ~400 deer I've taken, only one mule deer, rest are white-tails; over 100 have been with the 'Roberts. Any deer that have "escaped" an encounter with the 'Bob, it's been my fault. With anything resembling decent shot placement, it's absolutely fatal. I can't explain how much better it's been for me than the .243. No comparison in the field.....
My favorite load is 45.0gr of IMR4350 under either the 100gr Hornady flat-based Interlok, or the Sierra 100gr Pro-Hunter. The Sierra GameKing is no slouch either, but under 300yds the flat based bullets are more accurate IMO.
My second favorite load is the Berger 115gr VLD over 45.0gr of IMR4831. This is a real "sleeper" powder for the 'Bob. It took me nearly 30yrs to get around to trying it, but if I could only have one powder for the 'Bob, this would be it. This load gets just under 3,000fps from my 22" bbls. Unbelievable devastating on the three white-tails I've killed with it. The closest thing I've ever seen was/is my .338/06 with a 210gr Nosler Partition. Be sure to hit them in the lungs broadside with this load. It's too destructive for shoulder hits.....
A friend has a .25/06 and uses exclusively the Sierra 120gr BTHP GameKing, over 43.0gr of IMR4320. It gets 2,850fps, but shoots 1/2" groups from his Interarms MkX. I've teased him for the 'Roberts equivalent load... He counters with "Whats wrong with that, it WORKS, DOSENT' IT, HUH ??????
(three years ago, he took a 230lb 10pt buck at 430yds (lased) on a power line on the PA/WV border while hunting with a friend- witnessed!
Yes it does !!!!!!
) and have shot a few deer with it that stayed shot.
