Finally, I have a Bob. Winchester 70 bull barrel stainless in a super Grade LA stock (???) Anyhow, UPS snapped the stock and I have a used standard stock in LA coming off Ebay. No Idea of the history but it shot two minimum load rounds just fine -- 40 grains H4831 SC and a 117-grain Hornady BTSP. Drilled out stock at break, inserted long eyebolt, JB Weld 5-minute epoxy and sawed excess off after cure begun. Finishing up in safe next to GoldenRod. Buehler mounts re-installed with Leupold 3-9x. Everything cleaned up good, including the bore.
dang that sucks, those are a pretty good stock design.
I like RL-19 on top of a federal 210 or Rem 9-1/2 primer. the 120gr Hornady H-P does right well in mine. the Speer 100gr controlled expansion expansion bullet would also be a good one at the Bob's speeds.

Lousy luck with the stock, hope the replacement one works out for ya.
Enjoy your Bob! Excellent, versatile caliber for everything from varmints to large Deer. I like using 120 gn speers for hunting and what ever is on sale for fun. You can kill varmints with anything it will shoot. I would start searching for brass yesterday if I were you. If you like yours as much as I like mine you will want to shoot it a LOT! I have managed to find a couple of local brass bargains and jumped on them. It's getting hard to come by, but there is always the reform from 7X57 option.

Once-fired range brass (25) from Capital Cartridge, 50 new at Graf's for under 30 bucks, box of factory loads. I'm good. Just need to see if it'll shoot. Once the replacement stock is here, I can inlet and bed, probably with Steelbed. Test fired with range brass, one of which was 7x57 that I "formed" in 6mm Rem sizing die, then .257 Rob sizing die just for fun. Thanks to all!
117 Sierra's and max doses of IMR4350 produce tiny groups (.5") for my 257's. Lately we've been shooting 110 Accubonds as well with same charge and powder, very impressive.

Originally posted by butchloc: After it breaks again, use something better than 5 min epoxy. Quick set epoxies are not nearly as strong as their longer setting time brothers.
Your preferences, butchloc? It was what I had to fiddle with. Does extra bedding compound work? Not sure I'll redo but now's my chance to learn from the pro's. Anyhow, thanks again to all of y'all.

Replacement stock ought to be here today. After inletting, bedding etc. I'll get back to load development. Dang that barrel was dirty! Think he WD40'd it too. Shoots nice, though.
Early start at the range at 70 degrees. Went back after noon at 83 degrees, having cleaned the barrel and loaded some more. Not bedded, and I doubt I will. Anyhow, here's the result.
I noticed none of your pictures showed velocities. It may be a good idea to use the chronograph to help you determine your top loads. If they exceed the velocities in the reloading manuals, it could be another confirmation that your loads are too hot.
Your 4985 loads look pretty warm to me...

10-4. Trying to see if bedding worked or not. Today I had to adjust way down -- still blew a primer at 41 grains and wrecked a bunch of brass. Think I looked at the wrong data. Gonna wait for cooler temps now. (Got a trip to England next week and trophies from October might arrive before then, too.) Will chrony etc. at 38 grains as max for this rifle.
I shoot 44.0 gr. of IMR 4350 with 100 Nosler Ballistic tips in my rifle, which has the long throat. Mild, very accurate, ~2900 fps. Could push it another 100-150 fps, but it wouldn't make things any deader.

What! ?.... Reloading book velocities are not gospel you may not be able to reach those velocities or you may be able to exceed them, its all about what is max in YOUR rifle, no one elses…

not gospel but if your getting 3100 fps from a 2900 fps load and stretching cases and dropping primers out your seeing some pretty good signs you need to back things down in that rifle.
having a chrono would then prevent you from ruining another batch of cases long before you got to that point,,, and help the rifle make it another 10 years.

I understand what you are saying Lamar but to use speed as an indicator of an overload isn't reliable. I have some rifles whose barrels are fast and others slow, consequently "reloading book" velocity means nothing to me. Blowing primers and cracking cases now to me those are signs you have exceeded the limits. No matter what the velocity may be.

Updated: I picked the wrong data for H4895 -- since corrected. Looks like WW brass couldn't take the strain of max. loads. Chrony confirms my suspicion that I have a nice, tight chamber which yields (as does a custom 7 mm Weatherby recently done for me) slightly higher than book velocities.
This .257 Roberts is a heavy barrel stainless put together on a post-64 Model 70 action. It now fits nicely in a regular Model 70 stock which I believe is equal to the Super grade stock that UPS snapped. I bought it off Gun Broker and cleaned it up before starting to see what I have. Thanks for all the input.
After lots of work -- mounts (ring screws) shifted enough to throw groups off. Leupold bases and rings now, and I have a good load. Also, that factory load shoots well. So, a sorta skim-bedded replacement stock for the original (broken), fall temps coming soon, it's all good. WW brass is crap, IMR 4831 and H4831SC good with 117-grain Hornady SST's. Hornady brass is better.
FWIW, tell your wife she has some nice quilts. My mother, ex-wife, + a daughter in law are big quilters + over the years I have picked up a bit of knowledge on the quality of the said subject. Oh yeah, the Bob is pretty nice as well.
Ive never had any problems with WW brass, in fact I prefer it in my 257 IMP and other calibers..I also like IMI, Rem, and PPU..I load pretty hot as a rule. sometimes I suspect brass gets a bad name for a number of other reasons such as not being trimmed, too much powder etc,using a mag primer with a max load for standard primers etc..Regardless of the brass when primer pockets swell, when separation takes place, extractor marks, sticky bolts occur, your gun is suffering to one degree or another...
Bnagel, if you + your wife are ever up this way, there is a quilt "shop" for lack of a better term on the Southeast corner of the square in Georgetown where ladies of all ages meet, quilt, sell, + once a month hold a raffle. It's a pretty neat store. I haven't been in years but I can only assume it's still there.
