Home Forums Hunting & Shooting Ask The Gunwriters I’m confused 250/3000 vs 257 Roberts

A pic from the auction I bought...

The 250 AI is the one I'd really like......but then you are just .007 away from a yes, the dreaded 6.5 Creedmoor! Never was a Roberts fan, good round, but then you are almost a twin of the 6.5x55........they all get the job done no doubt. I do like the vanilla 25-06........it needs a big brother....commercialized..........

The Wins and Kimbers with blue/wood are nice.

Did you read the whole thread? Do you need Cliff notes?

So, exactly how many angels can dance on the head of a pin?

I've done both the 250AI and 25 Souper in short action Ruger 77s and prefer the 25 Souper 'cause it is easier, one run through the resizing die, and fed better in my 77 RSI.

That said, the easiest .257" bore round is the 25-06 and although I was a 257AI snob for a long time, I have come to appreciate the 25-06, even with a 22" barrel. The Marlin XL7 that I bought from someone on this site back in 2012 shoots the Hornady American Whitetail 117 grain factory load better than a $280 rifle ought to.

Yep.

If you want to make things easy with .25's, buy a .25-06. The ammo/brass is everywhere, and rifles normally shoot VERY accurately, even with loads that theoretically shouldn't, such as around 52 grains of either IMR or H4350 with a 100-grain bullet.

But real rifle loonies do not generally want to make things easy. Instead they're much like my paternal grandmother, who homesteaded by herself in central Montana in 1919. The line in our family was: "Grandma Bee didn't think anything was worth doing unless you did it the hard way."

There is a 28° Improved round, not just the 40° version. So 2epps is correct and you are wrong about being one a single Improved version of the .250 out there.

Layne must have magic dies. Considering a 250 Ackley has a 40 degree shoulder and the 6mm Creedmoor has a 30 degree shoulder.

PS: Give spell check a whirl.

A 250 Ackley Improved is 40 degree shoulder, period.

So AGAIN for the two of you that apparently suffer the ability to comprehend anything. It wasn't about TWO different IMPROVED versions, it was about the AI (Ackley Improved) having a 40 degree shoulder.

I was the guy saying you could neck up 30 degree shoulder brass and use it in a 40 degree chamber, no fireforming needed.


I wasn't the one that said the 250AI can have 2 different shoulder angles, that was your BFF again. The ACKLEY IMPROVED, has a 40 degree shoulder.

I'm sure this will befuddle you even more, so just drink a can of Ensure and take a nap.

What is it your time of the month? He thought the Ackley came in both 28 & 40 angles. Instead being a b!tch by saying only he was wrong, maybe you should pointed out (so others reading this thread might also understand) that even though there is a 28° version 250 Improved, it isn't considered an Ackley. Or is it because you had no clue about the 28° Improved version?

I Knew a fellow with a Bob AI, he ran it HOT.......VERY HOT....Great speeds, unknown pressures! So......yes I ran a Ruger 1B, Mild recoil, beautiful wood, shot about 7/8" with factory 117s.......only sold it b/c it was just too heavy for a sporter to tote around. Sure do like the little Blue BTs....never cared for the dull brown ones in 6.5, but they perform.

The little 25 BR was written up in Varmint Hunting magazine a few years ago....guy set back a barrel as I recall to 22", on a Ruger, a 1AB it seems, it was the lighter sporter contour. Shot 100s around 3,000 as I recall, with great accuracy. Also read about the Souper, IIRC, that is a 308 case? Speeds were VERY high, and accuracy Great.....it was an all out custom rifle using custom bullets as I recall. I would if the 250AI can easily be made by passing 6.5 CM brass thru a die? IDK. Just a thought, knowing they are very similar. A local shooter used to form 6XC out of 22/250, but it seems I found a few cases left over....that may had failed, not sure how many times fired.
