You should be fine with the 1:7.5," but as noted, I wanted more flexibility. Below is a factory 100g SP and with 117 Cayuga, which requires 1:7". I didn't want to short-change myself and not shoot longer higher BC bullets that are available to me, especially when I have a say on the twist rate ... but that's just me, but the ultimate choice is yours to make. Good luck!

I'm honestly not familiar with ANY other 257 bullets besides Blackjack. What are these others your talking about?
I am NOT trying to convince you to change your mind, just simply passing information that might be pertinent for your intended use. Below are the bullets I was referring to.

My build plan was to propel the 133 Bergers primarily, but I cannot get them at the moment, but I can get the above bullets.

The PVA bullets take a 1:8, and the Badlands 1:7. Wouldn't a 1:7.5 split the difference for all three?

Have you tried the SBD2 in your 257 yet? I'm getting great results with 25-06. Can push them to 3300 pretty easy but running at 3200 for brass life.
also what's your coal on the Cayuga? Considering a tikka 257 for the next build but need to keep it 3.4ish or less for factory mags

My brother has both. Hard to beat a good 25-06 but the 257 bee will. I really think weatherby has the 257 dialed in both gun and ammo wise.
Sorry, I have not. I still have another 5 weeks to wait for my barrel. The COAL of the Cayuga is 3.425".
I look at them as the minimum recommended twist rate. Just like Berger noted with their 133s (https://bergerbullets.com/product/25-caliber-133-grain-elite-hunter/)
The PVA used a 1:7" to calculate their BC. If you look at Blackjack Bullets' barrel blank recommendation in their inventory (https://blackjackbullets.com/product-category/barrel-blanks/?v=ed5e635ddcfb), the majority of them are in 1:7", including Bartlein.

To the OP, yet another vote for 257wby. My family has had great results with the 25cal 110 accubond out of my 257 and my father's 25-06. Our shots are consistently over 300 yards so I prefer the extra juice in the 257
Question for Feenix, with your 1:7 would you still be able to shoot a 110 accubond or are you "limited" to 117-135+? I know your goal was to shoot those heavier/longer bullets so you're not limiting yourself at all, I'm just curious if that option is available to still shoot 110s

I'm for 25 caliber anything as long as it doesn't end in Needmoor

I used a 257 weatherby for many years I did like the gun but the damage the 120 partition did to the animals I shot was crazy so I decided if I'm going to eat what I shoot I needed a gun that could shoot a heavier bullet and slow the speed down so now I'm shouting a 6.5/06 with 140 accubonds at 2950fps and it's a great gun and I have a lot less meat damage
