You lucky readers! After years and years of infield research I now know the ultimate cartridge for deer/sheep/pronghorn size critters! Additionally I have carefully assembled from my field notes all the facts you need know about ballistic coefficients, bullet weight, velocity required at sensible hunting ranges (let’s put max at about 400 yds.). So here you have the ultimate numbers: B.C. .390-.453 Bullet weight 115-120 grain Velocity 3000 FPS What those numbers make you yawn? They don’t approach many of today’s modern cartridges. Well record book Pronghorn and Rocky Mountain Sheep and several Mule and Whitetail Deer, Javelina and a Black bear wish I had never discovered the 257 Roberts!

I use my 25-06 for Pronghorn & Deer.
I get the same ballistics as you do in your Roberts.
Good round!

I have Whitetail hunted with the Bob for 20 years now. I killed my only buck mount on the wall with it.
I could talk about cartridges for hours, but I'm older and know nobody really cares so I'm gonna play the guitar a while and relax.

Well yeah, but what really counts is the outfield research. VarmintGuy is that you……..?

It's always been the Bob. Today we have better Bob bullets to make it awesomer....
It's you and the bullet, and all the rest is secondary.

When I saw the ultimate cartridge title, I thought someone resurrected Mule Deer’s B-29.
I guess the Roberts is OK too….

Cartridges that are nearly 100 years old don't work anymore. All that history doesn't mean a thing. If it wasn't designed in the 21st century it doesn't count.

The .257 is a good one. These days, it is seldom seen or heard about and It meets all the requirements of a deer/ sheep rifle. Just my style, which means, it is not short and fat, keeps a gentle shoulder angle and a longer neck. A 1/4 bore these days doesn't capture the attention of the " IN" crowd . It is a hunter's round.

Desertranger, As you know, I have some acquaintance with that cartridge, and so does Eileen. Below are some of the western big game animals we're taken with it over the decades. The first is a pronghorn buck I got in 1988, taken at around 450 yards with a 100-grain Nosler Partition. Back then we didn't know that you had to use high-BC bullets in 6mm or 6.5mm to shoot antelope at over 250 yards, so I loaded the Partition pretty warmly and used my scope's plex reticle to estimate the range. The bullet landed right where intended, and by some miracle the buck fell over. I got this mule deer about a month later, using the same rifle with a 120-grain Nosler Solid Base, range about 100 yards--a far more suitable distance for such an antique cartridge. Eileen got this cow elk a few years ago with a more modern .257, using a more modern bullet, a 100-grain TTSX. It stood quartering away at 123 yards (we had a laser rangefinder), and at the shot dropped, flopped its head a couple times and lay still. It wasn't the biggest elk in that country, but wasn't a calf either/ We've taken a few other animals with the cartridge, some from other rifles, I would guess at least 50.

I’m learning I don’t need a cannon to kill deer size game after watching grandkids kill deer and pigs dead with a 243. I’ve never owned a 257 Roberts, but I like a 25-06.
