Sole purpose is to shoot 75 V-Max at yotes giving MPBR a thought.

Off the shelf would be fine also if little is to be gained with a budget build.

I formerly used a 25-06 for this purpose. Most shots would be 300 and under with an occasional opportunity possibly out to 400 but rarely will the terrain allow it.

.257 Wby in a Vanguard is a consideration. I already own 25-06 brass and dies but not a big deal.

The .257" 75'Max has a .290 BC. The .224" 75 ELD has a .467 BC.

Pass a 22" 1-8" 224 Kreedmire and 75's at 3500fps...or better yet,88's at 3250fps.

Though in fairness,I've shot a gazillion .257" 75's in a goodly sized herd of rifles.

.257's simply cain't begin to hang..............

Stick, do you think someday the .25 will see the high(er) BC love other diameters have enjoyed the last several years? Seems like, for whatever reason, it has been left behind when compared to others.

I'm assuming it's due to marketing/sales/hype. Just curious.

Take a hard look at how much wind you'll be contending with at range. I see what you're doing - trying to shoot a laser beam since you don't want to need a rangefinder - but the wind is another thing entirely, and Stick's point about BC is, as usual, spot on. Maybe play around in JBM Ballistics with your conditions and different bullets to see what it means to you.

Thanks, is the Kreedmire 1-8 good for 88's and a good candidate for Remage?

We do have wind here, it's Oklahoma but I do try to call on calmer days.

25’s come with 1:10 twist or slower barrels. No need for long sleek bullets if there aren’t rifles to shoot them.
Someone would need to invent a new wisbang .25 round to market and then get a rifle maker to sell rifles for the new round.
But with current 6 and 6.5mm offerings there isnt much need.

Blackjack has been offering .257" 131gr SMK's,but I've had 'em on order for a few months now and nothing has arrived. I'd personally be VERY slow to build with a lone Sierra offering in mind,but was/am curious. My hunch is,Sierra will abort the effort and all will fold.

.257" OEM RPM runs from 14"(elder 99 Levers)to 10" as the fastest...none of which do favors...........

There are some high BC .257 bullets out now. A couple guys I know here in OK are building them. They are called blackjack bullets, 131 grainer is the match bullet. Several guys around here and surrounding states are chambering 25 creeds and 25x47's. There is enough interest in them that bugholes in carrying 7.25 twist bartlein's now.

BC is the SOLE function,that works to retain velocity. So with the advantage in wind drift,you reap the reward of higher impact velocity retention as well.

Many are consumed with starting velocity,which is a very different from impact velocity.

For conversation,with the .257" 75 'Max at a 4000fps start and a .224" 75 ELD at 3500fps,their impact velocities are identical at 300yds(2860fps). Though the .224" 75 has the wind drift advantage,starting inside the 50yd line and carries that edge forever.

At 400yds the .224" shaves nearly halfa fucking foot of windrift,arrives 120fps faster and "costs" but 3/4" of trajectory(with like 250yd zero) and burns a whole shitfuck less powder,to do same. Plus,you'll get a minimum of at least(1) extry round in the belly and the 224 Kreedmire will of course be more accurate to boot,wearing far more favorable ES/SD values in conjunction. But it do cost less to shoot,barrels last longer,recoil/noise are much less and brass is VASTLY superior...none of which are "concessions".

If only for starters.................

A 8" 224 Kreedmire at 22" stabilizes 88's in my atmosphere,at the coldest temps. Mine is a RemAge and less regret.

88's still do nice things,in calm conditions.(grin)




LOVE the chambering and I've prolly shot a "few" 25-06's and 257 Wby's...none of which can begin to touch it.



Mind Fuck...............(grin)

Would be interesting to see if the 25 could get a foothold in PRS or other type competition and get some industry support behind it.

It should be fine OAL-wise, just makes sure you're throated appropriately for the bullet you want to shoot. Loaded rounds need to fit, leave some space, and touch the lands. All that shouldn't be hard.
If it's a Remington factory DBM, there could be other complications I don't know about - never owned one.

I've had multiple 700 OEM DBM's in both short and long and without issue.

I'd not want more than say .100" freebore and that will give you miles of COAL latitude,as configured,squirting 88gr Smooches.

Nothing to fret................

Wish one of you enterprising souls would would build a Montana in 22 CM so I could imitate your success. It wouldn't ever replace the 223, and yet... we all need one.

That's almost the same thing, for sure. I would have bought a Fieldcraft in 22-250 7 twist if it was available, but I missed that train and I'm now glad I did. 22CM can't be far away, I hope, and 22-250 vanilla kinda sucks in comparison. And the Montana stock still carries the day. For me.

I'm not a 22-250 Guy,but just snagged another in 8".

Kreedmire is where it's at and a Montucky so configured,is THE Grail...................

I'll have to stay the dick rifle route as I'd have a hard time telling 22/250ai brass from a 22 creed without reading headstamps
I'm pretty sure I can't tell at glance the difference between AI brass and 6 CM as it is !............ grin
