Re: Anyone have experience with the .250 Savage in a 1:10 barrel?
Yes, you're on to something! It's amazing how this almost 100 yr old cartridge can perform. Marketing on the 243 is basically what did the 250 Savage in, but the two cartridges are remarkably similar. I grew up shooting a Mod 99 in 250, and have owned several others since.
The 250 Savage is great in a faster twist barrel. I currently have one built on an FN SPR action (basically SA CRF Mod 70 w/ DBM) and a Satern 5R barrel with 10" twist finished at 22". My varmint load is an 85 gr Nosler BT in front of a case full of H380. My go-to deer load is either the Sierra 90 gr HPBT and H4895 or the 100gr Nosler BT with IMR4320. My current rifle even shoots the green box ammo to under MOA, so it'll do in a pinch.
The 85 gr load shoots in the 3s consistently, and the deer loads are all 6s or better. I've taken quite a few deer, Pdogs, skunks, and one porcupine with the 250, and never felt like I was missing out by not having more gun. I do limit ranges to 300 yds on deer with this cartridge.
I'm currently working up a load using the 115 gr Nosler BT to see how that one does. Have to wait for a somewhat decent day at the range, though; last two times I tried to go we had 25-30 mph winds with strong gusts....also have some of the 120 gr pills to try, but not sure that they'll stabilize at the 250s velocities, so time will tell.
