Poll: Quarter bore project thoughts.

[orygun]

The Colton is center stage right now on the (loading and shooting) benches. Appears to send a 100gr Ballistic Tip 3400fps comfortably. Still a work in progress.

I can't believe a set of .250 Savage dies showed up retail! Gonna be the puppy in the window nobody takes home, even though it would be the best dog anybody ever had.

I'll keep my eyes on them. If they hang around long enough maybe I'll drag them home as the catalyst for another venture.

You can do no wrong.

Um…

No points awarded, huh?

Oh, yeah? My biggest "wrong" is too many serious hobbies. Just as I was getting rolling on gun stuff, it was time to put a racecar back together...
But I've not yet been back to BiMart.

I bought a Remington 700 ADL Varmint in 6.5 Creedmoor a couple years ago with the thought of getting into some long range shooting just for poops and bellyaches. Well, that's never going to happen at this point.

I have no use for the 6.5 Creed, nor the ridiculously heavy 26" barrel on it. But, I have been wanting a 25 caliber in the stable for pronghorn and light bodied deer for some time. I was looking at getting a .25-06, but maybe I can make something useful out of this ADL instead.

It will likely be put into a Grayboe Terrian or Outlander stock. Scope is undecided, but probably a Leupold, Trijicon or Nightforce.

I'm leaning heavily towards doing a RemAge barrel nut system.

I'd like to be able to launch 75gr - 98gr Hammer Hunter or Shock Hammer bullets @ 3000fps. I'd likely go with a 1:9 twist, unless there's a compelling reason otherwise.

As far as chamber, I've been looking at short action quarter bores and have come up with the 250 Savage, 25x47 Lapua and 25 Creedmoor.

Which would you pick and why?

Or is this a stupid idea overall? Should I just sell it and get a proper .25-06?

I think you could get to 3000 fps with the 250 Sav and 75 gr bullets, not sure about 98 gr bullets though.

I have a 250 AI that gets about 3175 with 100 gr TSSX's in a 21" bbl and about 38 gr of H4895; I shoot the 80 gr TTSX's at about 3350 and they would go a good bit faster. Mine's a Douglas XX bbl on a Marlin XS7 with the Sav barrel nut. Highly recommend the cartridge, RCBS has dies.

I really enjoy the 25's. Not too long ago I had a 24" 1-7.5 twist 25 SAUM built, I shoot the Berger 135gr Hybrid's. I currently have a light weight hunting rifle being built in 25-284 with a 7 twist. I plan on shooting the 133gr Berger Hunter's in it.

.25 SAUM. Along with a 100 yards group during load development. I can beat the heck out of clay pigeons set out at 720 yards.

Love for the quarter-bore is understandable, though not in the mainstream.

Y'all be crazymakin' wid dis stuff!

This evening I just shot two three shot groups with the 25 SAUM at 300 yards. One group with Bertram brass and one group with AGD brass. Both the same powder charge , same seating depth, same primer. 135gr Berger Hybrid.

In the wind. I dialed 1-1/4" MOA right for the Bertram group and then the wind dropped off a little so I dialed 3/4 MOA right for the ADG group.

The 250 Sav claim to fame was an 87 gr bullet at 3000 fps. It should do what you're looking for. You could check out a 250 Sav AckIey Improved too. I get about 3175 fps with 100 gr TTSX hand loads with a 21" 1:10 Douglas bbl. on a short action Marlin XS7 barrel nut bolt; 80 gr TTTX's are a couple hundred fps faster. I've shot a fair number of antelope with the 100's.

For some reason, I had it in my mind that the 'Bob was too long for a short action. I knew it was shorter than an '06 case, but thought it was longer than a 308 case. That's not true!

Looking at load data, the 257 AI comes pretty damn close to a 25-06, easily within 50fps with most loads.

That could revive this little project.

You can do it but you might run into issues with longer bullets.

Bullet selection was an issue with it. I could neck size and fire form my 250AI to a 6.5 CM. It's basically a 6.5-250AI, you can buy those dies off the shelf. I thought about it until I shot the 25 cal ttsx's, they solved that problem for me.

Just as a note, my long-action M70 featherweight in 257 Roberts and my old Ruger 77 mkII have long actions. The 700 you have is not only short, it's one of the shortest at 2.85". Don't cram the Bob into that!

25 Souper all the way! Neck up 243, neck down 260, easily hit 3000 with a 100gr TTSX.

Love that Souper idea, and I have a 722 short action gun I bought for butchering toward that direction, but I can't bring myself to carve up a nice 722! (Have a couple friends that would kill for it to do just that.)

Unsure about the Ruger, but that Winchester probably has restricted travel, due to the bolt stop, and a short magazine compared to the "real" long action. Changing the bolt stop, removing the magazine filler and replacing the follower with one from a 30-06 will give more than enough room for any bullet.
My 70 isn't a featherweight, but I believe all Pre-64 Winchesters were built the way I described.
I've not yet started handloading the Roberts. Looking forward to later this summer when time frees up a little. Thanks to a very generous member I have several different bullets to try out. Looking forward to the project.

Its a Shot Show Special from a few years back. I have a 257 Roberts and 7x57. The 257 does have a block in the magazine, but it still gives me 3.15". Depending on the shape of the bullet, I seat as short as 2.95", which would never fit in a 700. Oddly enough, it would fit in a current M70 short action with a WSM box or a standard short box with the block removed.
