6xc load data

Got to play some more for loads for an upcoming PD 'hunt', last trip used some data 85 on 70's, shot OK was cheap, compressed load was only 3300 FPS. I need more splat though.
All bullets are coated.
Have two rifles both 8 twist one is a 3 groove cut for 105/107's, other a 5 groove canted cut for shorter stuff, 3 groove needed a 'midrange' PD load, Berger 88 FB high BC's and RL17 3425-3450 FPS and shoots very very well, moderate pressure load.
The short range gun sticking with 70's (both blitzkings and Noslers) started out trying 8208 could not get above 3550 w/o pressure issues. 8208 reminds me of 4895 in some ways, you'll hit a correct node that will shoot like an absolute house of fire, but in between its junk and throws slugs everywhere.
70's and RL17, bam 3700-3725 no pressure issues and shoots very well at a near compressed load.
Usually pressure signs for my guns are typical- progressively flatter primer, then a primer crater, then sticky bolt/ejector mark, RL17 is odd, NEVER craters a primer, you go from a slightly flattened primer to a medium flattened primer then sticky bolt/ejector marks regardless of bullet weight. It must have a very smooth pressure curve or something, but if you desire velocity its magic, and seems to like being closer to max loads before accuracy occurs.
Haven't calculated spin rate at 3700 in an 8 twist but its got to be pretty close to max, didn't make any grey clouds, all round holes, and a quick informal fragmentation test says these things are gonna have some serious splatability at short range. Used some Berger 88's last trip, while they don't posses the short range splatability, even at 500+ if you hit them right they will get some serious air and shoot way too well at longer ranges and in wind to ignore. The 105/108 stuff will 'reach out and touch someone' at long range well, but tend to poke holes and be less humane, the 88 does the job better overall even at long range.
