Sounds familiar.

I have never annealed my brass, never even heard of it for many years but I was wondering does it really extend brass life? Is so, how much? Asking those with experience if they can quantify this? The picture is 257 brass that was used 3 times, resized 4 times. Normally I get 7-10 uses before I...

I have used IMR 4831 with good success pushing the 117 grain bullets. I settled on 42 grains as the most accurate although I did experiment with different increments up to 43.0 grains. I have done some testing just today with Hornady 128 grain ELD-X and IMR 4831. I started with 39.0 grains and...

Nice, there is no loading data for bullets above 120 grain for the 257 Roberts. But now there are 25 caliber bullets available in 128, 129, 134 and 135 grains, possibly more that I’m not aware of. I had a fast twist barrel put on my recently built 257, specifically to try the longer heavier...

I agree with your synopsis, this forum is like a breath of fresh air after Facebook.

More free bore can be added at a later date if you thought it was a necessity. However I do understand the logistics of doing it during the initial build. I have done that myself on. 257 Roberts, never regretted it.

After all these years and I still don’t own a chronograph. Does anyone have experience with the Magneto Speed? Thoughts and opinions welcome. I looked at the old style Caldwell but nobody says anything good about them. Here in Canada a Garmin is $750. All advice appreciated. Thanks, Abe…

The original 257 Roberts was loaded as I recall to a very anemic 48,000 lbs. pressure. The newer SAAMI specifications has raised this to 58,000 in the designated +P loads. Still shy of the 60,000 - 65,000 for comparable centre fire rifle cartridges.

I sincerely believe the 257 Roberts is a classic cartridge that deserves a better fate than the dust bin of history. As such here is what I have done to restore this cartridge to everything that I believe Ned Roberts intended it to be. The cartridge on the right is the standard factory offering...

The classic 257 Roberts as offered by Remington was indeed built on the short action. Which is its chief downside, chambering a medium/ long action cartridge in a short action rifle meant seating the bullet deeply into the case, defeating the generous case dimensions of the parent case, the 7x57...

I sincerely hope so.

I am a lifelong fan of 25 calibers and 257 Roberts in particular. My original is a Ruger M77 tang safety which I have added extra freebore. This rifle is very accurate and effective with 117 grain bullets. Over a period of more than 40 years I have taken everything from coyotes to moose and elk...

Hello and thanks for letting me join this forum. My first question concerns the 257 Roberts. I would like to compare the case capacity of the 257 Roberts with the 257 Roberts AI and the 25 Creedmoor. I haven’t had much luck find ing a source for this information and the sources I have found have...
