I printed out VV's data for 69, 75, 77, and 88s. I might try some head to heads against the H322 loads I have. Their 88gr load is a short OAL... .177 shorter than I load, and their data is low velocity.

Loaded and shot 3 different bullets yesterday. My first impression is that the powder is similar in performance to H322, which is a good thing.
The powder looks like it will meter good in my Dillon 550b, but I ran these 3 loads on the chargmaster.
69 gr RMR with 23.5 gr (.3 under max) ran 2781 fps S.D. 10 (20" bolt gun barrel)
77 gr TMK with 22.5 gr (published max) ran 2667 fps S.D. 7 (20" bolt gun barrel) This load nearly matched our 22.0 gr H322 at 2660 fps S.D. 6
and,
The 88 gr ELD with 23.5 (over max) ran 2775 fps S.D. 10 (23.75" bolt gun barrel)... compared to 2797 fps from Varget 24.5 gr.
I don't think the N135 will be able to safely catch Varget's velocities. Maybe N140 could get there, but we don't have any of that powder.

I took the opportunity to shoot VV only in my new Colt 14.5 barrel yesterday to observe the clean burn claims I've read about VV over the years.
The bore and BCG definitely appeared to be cleaner than I'm used to. The bore looked clear instead of the normal small particles you normally see before patching the barrel.
And the BCG and very little carbon fouling inside, and the bolt tail had very little carbon build up.

Recapping this stuff... with the 69gr RMRs, we started out 3/10s under max, and had modest velocities right? So I bumped up to Max and shot some more last weekend... no problems. So I loaded hundreds of rounds of the same load and yesterday primers were popping like crazy.
So sick of popping primers.
