25GT (25-6GT) vs 250 Savage

[wapitiaddict]

I really like the quarter bores? I was reading about a couple of guys that did a 25GT (necked up 6GT). The purpose of a 25GT is to use the heavier, higher bc 130+gr 25 cal bullets that would be easier to spot misses (than a 6mm bullet), but the lower recoil of the 6gt case capacity than the 25 Creedmoor.

I really liked the thought of that for a build, but then I got thinking....would the 25GT case be pretty comparable to a 250 Savage capacity wise? Would the 25GT be somehow more "efficient"? Maybe the 250 Savage is not as easy to tune loads for?

Anyhow, I like the idea of a 25GT, but if a 250 Savage can get me the same thing without having to go full wildcat then I think that would be a better route for me. (And yes, the 250 Savage would have a fast twist too)

Thoughts?

P.s., please try to keep it between these two calibers. I know the 6 dasher, other 6BR variants, and 6.5-47L are great cases, but I'm not asking about those. Just thought I would get ahead if those comments

I had a .250AI for years. I think it was very similar to a 25CM. I could run a 115 @ 3100fps from a 23" Lilja.
Way before the .257 heavies were available.

The .250-3000 Savage has a LOT of body taper and a 20° shoulder, so they feed like butter. But the .250-3000 name was derived (before modern powders and bolt actions) from the ability to push an 87gr bullet at 3000fps. A 100 would run around 2880. A 115 maybe 2750. So todays heavies maybe 2600. But looking at today's powders and modern actions, I would think you could get 2750-2800 in the .250 Savage nowadays. I have often thought about a new fast twist .250AI again....because you can always load an AI DOWN to parent case speeds....but not vice versa.

A 25x47L wpuld be another GREAT choice if you don't want to go 25CM.

What 25cal cartridge have you not had, Lance??? Haha

2800-2850 out of a 250 savage would be about where I'd like to be if it's possible. I think the original 87gr at 3000fps was pretty mild pressure, right? Like you indicated, with modern brass, powders, and actions, I would think it could be pushed a lot more.

I was also thinking about the 25x47L, too. How would the case capacity compare to a 25gt, do you think?
