TentmanWhat will 1:10 stabilise in 257
Hi Guys
My 250-3000 has a 1:10 twist, do you think it would stabilise the Hornardy or Nosler 110 grain projectiles - I should be getting an MV of about 2700 with load, 35 gns 4320 ??

Greg KThe 110 Accubond shoots into 3/4" groups out of my 25/06 with a 1:10 twist. So I would answer yes to your question.

jeffeossomight have trouble with a 120gr TTSX -- but unless you have a store of the old 140/145gr hornady's, it will stablize just about anything

416RigbyHunterYour 1:10" twist will stabilise ANY weight 25 cal pills, anything slower than this and you would have problems with 120gr pills.
Even lower velocities would produce even better accuracy with this twist rate, as a 1:10" twist is still a little fast for 75-100gr pills.
Chers.

Code433 grains of 2208 did not stabilise 120 Partitions in my 1 in 10" twist 250-3000.

Wow - if you still have a hoard of those .257" 140-grain Hornadys, I'll buy all you have!
j/k
As long as the OP keeps velocity max (for a bolt gun, not the 45,000 cup for M99s) he should not have problems with commercial cup-and-core .257" bullets.

Slowpoke SlimYou should be fine in that 250 Savage driving the bullets near max.

Alberta CanuckA 1-in-10" twist reliably stabilizes 130 gr. bullets from my .25-06. Now my problem is finding more bullets of that weight for it.
