Well, the 257 Roberts I was looking at didn't happen but, a 257 Weatherby followed me home! It is a gently used 26" #3 fluted barrel model that I'm looking forward to breaking in. It also has a threaded muzzle so, I'm planning on using my suppressor with it 'hog plinking'.

For brass, I have heard mixed things on full-length sizing 7 Remington Magnum indicating the necks come out slightly short. Is this a viable option or do I need to search for and pay up for factory Weatherby brass? For tough bullets to crash through hog shoulders without disintegrating, what bullets will work well at distances of 50 yards to ~250 yards? Where I shoot feral hogs, the treeline is ~200 yards away. I'll worry about 'speed goats' when, or if, I get closer to a hunt in wide-open spaces.

115 NP's.

100gr interlock is what I am using in mine. Very Accurate and priced great ($39.99/20). I need to set the rifle next to my LabRadar but the box says 3,500fps.

Just don't buy once fired brass, sometimes you can get away with it on a belted magnum and sometimes you can not.

257 Weatherby is one of my favorite cartridges, nothing is flatter shooting (well probably).

100 gr Barnes TTSX or 120 gr Nosler Partition.

I used nothing but 264 and 7mm rem brass for years in my 257 Wby. The only thing I would caution is Wby brass will have slightly more capacity than 264 or 7mm brass .So a load listed as max in a Wby case will be excessive in a Win or Rem case. Your max will be 2 or 3 grs less than the max in a Wby case

Great cartridge. I use mine for deer and antelope.
I always buy new brass, not cheap, but don’t use a lot of it, so.....

Really fun cartridge. I thought I needed one since I first read about a brain shot on a crock at 400 yards with one in Death in the Long Grass. (I was just a little kid - I didn't know Capstick was mostly fabrication.)

But I finally got one a few years ago and have had a great time with it. I've had terrific accuracy with the 100 gr. TTSX out to silly distances. It's the best coyote round I've ever played with.

I bought a sack or two of Norma brass in bulk and they've lasted great. Lee will custom make you a neck collet die and I don't think I've had to toss any cases yet.

I recently acquired a Euromark in 257 Weatherby, been shooting some different loads in it. shoots 100gr ttsx with 7828SSC at 3550 fps, 110gr Accubond at 3400 fps with 7828SSC, that will kill any hog dead

Took my .257 Wby out this weekend to shoot the cob webs out. It is an Accumark Model that has served me well for Whitetails and Mulies. 120 grain Nosler Partition loaded at 70 grains RL-22 chronographed at 3425 fps and a 3/4 inch group. Also had two old loaded rounds with 100 grain Nosler E-Tip (no lead) with 71 grains RL-22. I shot them just to have the brass for next session and they averaged 3665 fps and danged if the two shots touched each other. When I checked the load date of those two rounds it was eight yEars ago. Guess I found a good bean field load. Good Shooting.

Thanks everyone! It sounds like I have some good options for this rifle.

The best tricks I’ve learned for sizing/salvaging belted brass that stubbornly refuse to size down to your chamber are the Willis tool, a small base die(300 Win works for almost all of them) and a feeler gauge between the case holder and the shell-holder.

The 7mm Rem necks down fine. Shorter but thats not such a bad deal if you hate trimming cases.

For quite awhile the cheapest way to get .257 brass was to buy the cheapest Weatherby factory loads.

A very good deep penetrating and hard hitting bullet is the 100 grain Scirroco.

Brass is not cheap, but it’s not like you’re likely going to shoot 100s of rounds each outing. So I buy factory 257 wby brass, and recommend that option.
My 257 wby is a custom sako with a 26” shilen barrel. It’s by far my favorite long rang deer and antelope rifle.

In my two current .257s I started by resized new 7mm Remington Magnum brass, this is cheaper and works fine with the heavier bullets. Still, I now use Weatherby brass from Norma and PMC exclusively in both rifles. Since the brass lasts a loooong time when properly sized, even the most costly brass becomes cheap on a per shot basis.
