It depends on what I'm trying to accomplish but I like them around 10 fps. The 22-250 that I shot in local short range BR matches years ago would shoot an honest sub .25 MOA AGG (from a factory Savage LRPV) with a lot of 5 shot groups in the .15" range. The SD on that load was 27 fps! It was tuned specifically for 100 yards though so it didn't matter. This load is from my 27 Boondoogle shooting the 170gr Berger EOL out of a 25" barrel. The groups at 280 yards were terrible with 3 MOA of vertical!I just stopped worrying about it and just shoot for groups now. If I get a load that will hold .5 MOA at 200 yards I'll go straight to shooting at 800+ and see how it does. I willing to accept that I can't always shoot well enough to blame a 10 SD for a missed shot at long range. Sometimes I just plain miss.

Goes to show that looking only for SD won’t mean your going to get good groups. I usually end up around 15 with a load that shoots good at 300. I strive for 1” at 300 as I know “shoots good” is a loose term. I would try some different primers, and your prep with inside of necks. Caliber up Nylon brush works good. Or dry neck lube in the necks followed by brush.
I find it’s easier to find the flat spot the fine tune with seating depth

Run a velocity test over the chrony and then tune depth. Brass prep and consistency is a big part of low ES in my opinion. But let's face it, for most of the ranges guys shoot, an ES of 20-30 isn't gonna make a bit of difference over 10-15.
When I’m starting load development I’ll start with a low charge. Load up some 3 shot groups starting at .015” off the landes or mag length which ever is shorter and seat each group deeper by .030”. Which ever shot best I’ll use that seating depth for my load work. I shoot a ladder over my chrono ( I use magneto speed, must have an accurate chrono for this!) target dosent matter. Look for my upper flat spot near max. Then I’ll load up 5 shot groups and fine tune my seating depth in .005” increments. If you don’t have a magneto speed or labradar then you could do 3 shot ladder test at 300 yards. This is my method that’s worked well for me. Yrmv
