What about the tumbling design we hear rumbles about? Anything to that? To be clear, I'm not looking to cut 'em down. I want them to work because I'm always looking for advancement. I like high BC in a terminally effective projectile but would be hard pushed to give up terminal consistency for a higher BC.
@codyadams, maybe you covered this before, but would you put them in a similar class as the Badlands? Wish there was a 170 class Badlands option for my 8 twist. Thinking to try the 170 Cayuga's in my 7 Allen till next year. With the short barrel life that goes with such an over-bore, I like to have a pretty solid degree of confidence in the end result before taking the time and barrel life to develop a new load.
Those of you with experience with both in multiple case designs, what would be your educated guess on velocity potential from the 170 Cayuga based on the comfortable 3,665 I'm getting now with the 150 BD-2? And what powder would you start with - Retumbo? The RL-33 did the best with the Badlands and the Bergers, but I understand the Cayugas pressure up different. By the way, this is a long range elk rifle. I'm just taking some deer this year in the experimental phase. Hoping to try elk next fall.
EDIT:
Looked back in my records and Kirby had actually tested the 195 EOL. Maybe I should play with that load a bit as that gives some serious long-range numbers. Here's his data for what he did in my rifle: (maybe this will help you tell me what a 170 Cayuga will do?)
195 gr. Berger EOL
100.0 gr. RL33
Fed-215 primer
3.680" oal
3300 fps average
