I had one of those from that era and used +P ammo regularly. Also the +P ammo isn't all that hot. +P .257 is at ~ 50,000 cup. Yep. You'll have a large safety margin. Even the +P 257 ammo is pretty tame compared to other cartridges the Model 70 easily handles.

I've recently joined 24hourcampfire and feel it will be not only a great source of information but educational, as well. Now, my question. I recently purchased a Winchester Model 70 XTR in 257 Roberts built in 1987. I am wondering if +P ammo is safe for this rifle. I do have some 117 grain Remington green box but would like to get a little more "pop" out of it and +P ammo gives me more ammo options. Thanx in advance. That's a sweet rifle in a cool caliber. Where you from?

As has already been mentioned, that rifle can easily handle +P. Not that the Roberts needs it. It is a decidedly good killer at non-+P speeds, and that Remington round nose will wreck innards.

I’ve always thought I’d like to own one. They seem to be a favorite of those who have them and shoot them.
Question to you fellas? Do you get pass through generally speaking on mature whitetails?

GN308, I always liked that photo! Looks like he might have come from the upper right downhill and gave up the ghost in that draw.

My experience was limited to the 120gr Partition at 2,850fps or so. It didn't stop in deer. I wound up moving to the various small-cased 6.5mm rounds for this role, as well as the 120gr 7mm-08, but if the typical deer hunter has a well-loaded .257 Roberts in hand, he is just as well off.
And that is a really cool photo above...

I was on the left ridge top (taking a leak) when I saw him vacuuming acorns straight uphill on the other ridge. Entry was high shoulder. THEN a 100ft slide for both of us. 🤣

I have 2 of the Roberts, one is a Hyper Single falling block and the other is a 722 Remington that I bought from Mike Walker. They both work really well with the 120 Partitions.

Your M70 can handle far more than +p .257 Roberts. .257 Roberts +P cartridges are held below 58,000 PSI. The .270 Win, chambered in your same rifle, has a SAAMI max of 65,000 PSI, a 12% increase in pressure. And it is safe to load the Roberts to that level for use in a rifle suitable for that level. It's not "necessary", but there's nothing wrong with it if you can find tested data, which is the problem part. You can trust the loads posted by John Barsness, "Mule Deer" here on this site.
Cheers, Rex

Have used the remington 117 round nose with good results out of my 257.

I have no problem pushing the Roberts in a modern rifle with good brass. This one is on a long action 700, 24" Brux. It shoots sub half MOA with 100 TTSX over 47 gr. H-100V at 3,266 av with low S.D. and E.D.'s. Hunter's Edge stock, Conquest glass. Hammers WT's and hogs. Ya about gotta reload if you're going with the Roberts, IMO. DF

Hey Dirtfarmer,
That reminds me of back when two of us headed over to the gunsmith's shop with 2 complete M700 actions; mine a LA, and my buddy's a SA.
Mine was a .257 Roberts built around the LA and my buddy's SA was used to build a .257 Souper.
Afterwards, we spent the next decade arguing which was the best cartridge. All that got resolved was who was the best shooter, and I 'aint sayin' who...
Mine is Lilja stainless, fluted barreled at 24", black McMillan stocked, Gold Ring glass, with all the metal cerakoted OD Green.
These days all I feed it is 110 gr. NABs in front of 45.5 grains H4350.
It's you and the bullet, and all the rest is secondary.

Beautiful rifle Dan. While I've had a number of synthetic wrapped 257 Rob's, I prefer it in chromoly and walnut. Mine: It shoots too:

My 257 is one I built on an Eatons 100 (FN) rifle which I picked up at a gunshow. The barrel is a gain twist which finishes at 1 in 12; a little too slow but the barrel was priced right. It shoots very well with any 100 grain and also stabilizes Speer 120 Spitzers and shoots them well. It's an easy cartridge to like. GD
