PVA Cayuga Terminal Performance

I played around with the 122 cayuga 65mm, it shot very well, just not my idea of terminal performance. Load dev was really simple. 3450 from a 65saum, 3320 from a prc.

I'd call up Mcguire and try some his 93gr copper rose bullets if solids are a necessity.

What was your load for the prc? I'm getting my 25 prc tomorrow. I need some starting point.

That was 4 years ago, didn't keep the notes as I sold that rifle. I was using rl23, prob 56-57gr. The cayuga is a bore rider design, with a front drive band, then an interruption to a pretty short bearing that goes in the neck. The generate low psi, so faster for bullet weight powders do well. The 65saum was using 60+gr rl26.
 
How so? Inconsistent, or just not enough wound channel?
Yeah I didn't care for the lack of trauma caused internally. Put a few antelope and a large body mature mule deer buck down, they weren't going anywhere, but required knife to incapacitate. 4 yo bull took 4 rounds, was quartered away, the first 3 were a small group entering prob 6 ribs back, exiting through offside armpit. Ice picks through offside lung. The elk stood there like I wasn't even hitting him(630y) I couldn't see splash as they were exiting behind. I actually thought I was missing, 4th shot I was like screw it, went high shoulder and the elk collapsed.

This was from a 65saum running just a tough over 3400fps. I recovered the high shoulder round some how, the nose was broke off, barely expanded over bullet od. Not my desired bullet performance.
