Home Forums Hunting & Shooting Ask The Gunwriters Why 115gr & 120gr .257 Partitions?

I believe it is. Serial No is 179,000 my reference said it was made in 1951. Does that sound right?

I've owned 6 .257s, 5 .25-'06s, and 1 .257 Weatherby. (Plus a .25-20 and a couple .25-35 but those don't count.) In my guns but 1, all nominally 1-10" twists, the 120 has outshot the 115. The exception was a Ruger 77 Mk II V/T, the first run of target gray rifles Ruger sent out. It liked the 115. It's possible with a different selection of powders, my results would have reversed, who knows?

I assume the 115 grain .257s are like the 95 grain 6mms ... for the 1-12" twist .257 Weatherby just as the 95s were first for the 1-12" twist .244 Remington. Just a guess though. I didn't look it up.

I thought it was due to the 244. But that was just an unproven thought, I have a 244 and never tried heavy bullets. I have a couple of 6mm's and they are along the lines of a deer rifle (lighter for one thing).

I have 115, 117 and 120 grain Nosler partitions on hand.

I just sold my 700 classic 25-06 - it didn't like the 115's - at least the loads I tried. My old ADL shot much better with the 115's with those loads. I "really needed" a 257 Classic, down the road the 25-06 Classic went, without a lot of load testing. I picked up a new in-the-box 257 Roberts Classic at the Tulsa show -- I'm afraid it won't stay un-fired long.

I just posted some range results with this bullet over on the other related thread:
