Re: .257 Weatherby, help me build it...

Had a good week at work, think I'm going with the 700 LSS instead of the SPS, still a slight toss up between it and the Weatherby though. It just felt too good for an out of the box gun when compared to the SPS and I could always sell that laminated stock if I wanted to.

Re: .257 Weatherby, help me build it...

I have two .257 Weatherby's. One is a Vanguard and the other is a Remington LSS. The cheapest way is to buy the standard Vanguard. Look at the test target before you buy and pick the one with the best target. I know that the test targets are shot in a slave stock at the factory but I have found that they show the potential of the barreled action. My Vanguard came with a .750 test target. It shot that with the recommended Weatherby 100 gr. ammo in the tupperware stock.

I have since installed a B & C stock with the aluminum bedding block. I originally planned to bed the action and free float the barrel but it shot the same Weatherby ammo into 1/2". I have shot one 3-shot group with the 115 Bergers and it was 1/2" I will be doing more testing with the Berger.

The second rifle is the Remington. It shot the Weatherby 100 gr. factory load into .750 It had a tendency to shoot two in one hole and the other off a little ways. I noticed that I could move the barrel sideways in the stock. It felt like there was a notch in the pressure pad at the tip. I am guessing that the barrel was moving sideways when fired. I put a shim under the receiver ring. This free floated the barrel. Two three shot groups with factory ammo produced two 1/4" groups. I am in the process of piller bedding the action and free floating the barrel.

Velocity between the Vanguard with a 24" barrel and the Remington with a 26" barrel is 50 fps.

The Vanguard costs $399. The B & C stock was $225. Total $624. The Remington was $789.

If you can look at several Vanguard's test targets and pick one that is .750 or better you can add the B & C Medalist stock and have a gun equal to the Sub-MOA with a better stock.

Vanguards have some very good test targets. My .270 WSM came with a test target of .389 It shoots around 1/2" in the tupperware stock.

Hard part is finding the action about 2 wks ago got a new 257Wby from the gunsmith. Use a Ruger M-77 action old tang safety was 7mag gunsmith order a new BC stock and 1/9 twist Shilen select match SS barrel #3 plan on using nothing lighter than 100gr bullets.

I had pretty good luck with a 300WBY no Wby freebore and headspace on the shoulder like a non belted case so had the gunsmith do the same thing to the 257Wby. Barrel was so marked. I had the action matte blue and matte SS on the barrel and barrel finished a 25" with 3.5x10 leupold scope rifle weights just under 9lbs.

The thing without the Wby freebore is you don't need as much powder to get those Wby velocity and your max load is pretty close to the start loads for the Wby and your cases last a long time. With 66gr/IMR-7828 115gr TSX @ 3436fps and it's a good load and with the Redding type S die I'm at 6 neck sizing on a case and looks like I may get to ten firing before I have to FL size.

So does the Remington have the oft debated Weatherby free bore?

Re: .257 Weatherby, help me build it...

And what about bullets? I see on Weatherby's website they now offer a factory loaded 80 gr Barnes TTSX. With the TSX's ability to hold together well and instant dirt nap reputation, would the 80 gr be too light for 200 - 250 lb MS whitetails? Without the ability to handload at the moment, I am dependent on factory ammo so I'd like to spend my $$$ wisely. I was considering the 110 gr Accubonds pretty heavily but now the TTSX has me kinda interested...
