.257 Roberts ?

you need to make sure the twist rate is at least 1-10. 1-9 is better.

in a strong modern action, there is no reason that the 257 rob can't be loaded to approximate 25-06 velocities. performance on game is fine
 
I believe it is 1:10. It's a Kimber hunter. I already own and load for .243 and .308. In short action, the rifle is available in .243, .257,6.5 creed, 7mm-08 and .308.as the rifle weighs 5.5 lb, I am ruling out .308. I know .308 isn't a big kicker as a rule. But in a light package it can be.

you really need to keep in mind the fact that higher velocities equal higher felt recoil. only you know your tolerance level. light barrel combined with high velocity will limit your target groups to 3 shots before things go awry. all of the cartridges you list are kissing cousins. all of them can have their performance dramatically increased with hand loads.

that rifle will likely be very accurate within its limitations. i sincerely doubt it will be fun to shoot. Do your own due diligence, this is all up to you in the end.

with only one exception, every person i know that commissioned light weight rifles developed serious flinches before learning to shoot them. internal recoil dampeners and the best butt pads available are a must.

use your big head on this one. maybe compromise on a mountain rifle configuration. If a couple of pounds of extra weight makes that much difference, i would suggest there are other issues involved
 
257Rob is a good versatile small game and deer cartridge. Lots of good bullets available like TSX, Accubonds, Partitions etc.
It's got a little more smack then the 243, but I'd consider them sort of equals for the type of game they are suitable for.

If the purpose is strictly a deer rifle, can't go wrong with the 257bob, or even the 243. The 7mm08 might be the best choice of all if you might want to pursue anything larger.

I feel like the 243 gives better versatility, being well suited for light weight varmint bullets as well as 90-100gr deer bullets.
 
This will be a deer rifle pretty much exclusively. My current .243 is only 3/4 lb heavier and it is pleasant to shoot. I have several heavier rifles but I find myself gravitating toward lighter ones as I get older. My long action needs will still be served by rifles in the 7lb bare range. I never had any dealings with the .257 before. Is brass scarce? I may go for another .243 yet. Decisions ,decisions.
 
i used a .257 Roberts as my dedicated deer rifle for about 20 years. Worked perfectly for close in forest whitetails and wide open prairie mule deer too. I shot perhaps couple dozen deer and a few other critters with it. I mostly loaded 117-120 grain bullets in mine, just personal preference but 100 grain bullets will kill deer just the same as a .243 will with that weight, and the Roberts will shoot them a tiny bit faster. I liked loading the 120 Nosler Partition at 2800 fps. Accurate, deadly, and flat enough for shots to 300 yards, at which point I stalk closer anyway. The 120's almost always give an exit hole on deer, which I like. Especially for hunting in the bush. And they also do a good job on black bear. I think the .257 is far superior to a .243 as a deer cartridge, but only with the heavier bulelts. I have also used a 25-06 and a 7mm08 a fair bit, and it gives up nothing to those two for most hunting. I'd still be shooting that Win M70 fwt but my brother in law talked me out of it.
 
It makes a great deer cartridge, Have taken a few deer with the one I had, cup and core bullets work fine so bonded bullets should work as good or better. Most bullets from 100-120 grains will do the trick
 
My method when buying brass for less common cartridges is to buy a couple hundred. Done. Higginsons lists Winchester: 257 Roberts +P = $39 / 50.
