N560 and N565 are great for the 7 saum.
N560 63.3 grains 175 elites 2970' 22" proof 1:9
N560 63.0 grains 175 elites 3008' 24" proof 1:8.4
N565 65.5 grains 180 hybrid 2942' 24" proof 1:8.4
N560 63.3 grains 175 elites 2970' 22" proof 1:9
N560 63.0 grains 175 elites 3008' 24" proof 1:8.4
N565 65.5 grains 180 hybrid 2942' 24" proof 1:8.4
We're you crunching powder with 65.5gr and the 180s?
No sir. I have a long freebore on Long actions.
Well loaded up 61.7-62.6 in .3gr incrememnts
61.7-3008 avg sd-19
62.0-3037 avg sd 8
Stopped there because bolt started to get slightly heavy. It was about 72 deg out and most likely will back off as I shoot in AZ and summer temps can get pretty high.
This was in a SA 2.96oal

Well that's a pretty good velocity since your having to seat them so deep. I would suspect that you would want to be around 61.0 for the SA. I'd go down to 60.0 then try every .3 increments. How far is your bullet off the lands at that distance all my coal's are around the 3.060" mark

magneeto batteries died but decided to shoot the loads anyways since I made the trip out to the range this load fell on 61gr. Started at 60.8 in .2 increments up to 61.6. I'm guessing this is somewhere right above 2900. OAL 2.96"
.559-.284=.275"
.559-.284=.275"
The plan is working. Nice job. I'm guessing 2,950 or so
Very very nice. Told ya that N560 is magical in the saum. Awesome. Happy for ya for sure.
Mine were with 180 hybrids but @Longtine88 had velocities with the 175 EH as well. They're listed up too I believe
