Planning a 250 Savage Build - Two Barrels, Many Questions

[std7mag]

Have you been able to stabilize the 120 grain bullets? I know the higher velocities you're pushing will make a difference, but the information I've seen on bullet makers' web sites and such seem to indicate 100 to 110 grains are about the limit on stabilizing with a 1:10 twist. If you can stabilize a traditional 120 grain bullet, I wonder how heavy a copper solid you could push? I think it's just a matter of time until most public hunting spots are forced into that.

Between the two rifles, I have generated probably 140 rounds of once fired brass. As long as I can get factory ammo and keep generating a supply of brass, I would prefer to do that. I would like to avoid having to worry about head stamp mismatch, especially since these rifles are to be used by multiple family members.

Bill,

I shoot the 120gr Sierra HPBT GameKings from all my 25 caliber rifles.
My Savage Axis II in 250 Savage also.

Want a round for deer that will blow your socks off?

That's great to hear! Did you have to have the throat pushed back to allow those longer bullets, or have you been able to do that with a SAAMI spec chambering? I've been concerned that some combination of throat depth (freebore space), relatively slow 1:10 twist, and possibly OAL limitations would keep me from getting to that 115 to 120 grain range.

Have you been able to check muzzle velocities on that 115gr round with RL17? I'm curious how fast you are pushing those.

Some data for u on a 115. These are at the low saami spec for pressure so can be easily and safely surpassed.

Im guessing hes gettin plenty more juice with RL17.

That's a pretty good starting point for 115 grain bullets. I wish I was in a position to start reloading today.

The 120s push into the casing some.

It's not as bad with the 115gr Bergers. Shorter than the 120s and they like to be up close and personal to the lands.
Note, being 0.005" off the lands does increase the recoil impulse vs say the 115gr NBT at 0.02" off the lands.

With the 100gr NBT & up bullets, it's more of a 100 yards or under rifle.

The 90gr Sierra BlitzKing, now those are deadly on coyotes out to about 400 yards so far.

I've shot the 75gr Sierra HP Varmint out to 400 yards with good accuracy also.

I'm running a 24" sporter barrel.
