Thanks to Everybody for the help.
I made up 20 rounds of ammo, 10 each of Varget at 34 and 34.5 grains using Hornady Vmax 55 grainers.
Got out to shoot and all went well. Groups for the 34s seemed a little tighter at about an inch with the 34.5s looking pretty good too.
It was real windy and I wasn't at my best for steadyness so groups are likely to improve.
The good news is they all shot well with no signs of problems.
I'm going to load up 3 new batches at 34, 34.5, and 35gr to try next time. With the max listed at 36 I intend to stay away from that as it doesn't seem necessary anyway.
I also have some Vmax 50s and Nosler BT 40 grainers to try. This barrel really liked the Rem UMC 50 grain bullets so that weight may prove the real ticket.
The ram prime works fine, but a little slow like was said, but fine for my purposes. But, it requires me to remove the seating die and then reset it which is a bit of a hassle.
I might try the Auto Prime outside behind a brick wall or something later!
SO FAR, SO GOOD! This is feeling alright.
