RL 26 will probably be your best bet. Shoot same bullet in my 25-284, but that won't help you any.
I was going to try it but I thought a 1-7 twist was a little crazy to fast in a 257 weatherby.
Won't bother the Hammers.
Berger said their products should be fine in a 1:7 when I emailed with them the other day.
I am sure, I shoot the 115 at 3400. I haven't lost a jacket yet, with a 1-9. But maybe my next one will have a 1-7 for the hammers.
I have a 257 Bee and shoot predominately the 100 grain Barnes TTSX for an all round hunting bullet. Just curious as to why you guys are moving to the ever heavier bullets, they don't seem to have all that much better a B.C. Not criticizing, just curious.
The heavier bullets retain more energy farther and drop less at distance.
I just did a quick calc on JBM and the 100gr only Carrie's 1000lbs of energy to around 550 yard and the 128gr HH should carry 1000lbs past 700 yards.

I am a heavy bullet fan. A .257 WBTY currently in the works to primarily shoot Berger's 133. As @Hoss50 noted, it has higher BC, less drop, and higher energy at POI. If the 133 Berger propels at 3000 FPS, at 900Y = 1912 FPS and 1080 FT=LBS.
Haley,
Contact Steve or Brian at Hammer, I am sure they have tons of load information for you,

I did. He gave me a starting point for a couple powders I have. I was trying to see if anyone on here had experience with it though.
Copy that! My apologies, I fat-fingered your name.

I will watch this thread with great anticipation. I also have a 257 Wby being built to shoot heavy bullets. Right now we are using 131 Blackjacks but once the new Bergers are available I plan to get them in the mix and also have looked at the 128HH. Also want to try the 117 Cayuga. My gunsmith told me he is getting 3350fps with the 131Blackjack and H1000 in my rifle. I do not have the load data yet but should be getting the rifle in the next couple of weeks. A quick run of this through the ballistics program shows pretty good potential!
