I bought 1000 of these a while back. Haven’t gotten the accuracy I was hoping for yet.
There are 3 versions (or more) of the 55 grain Hornady soft point: boat tail w/ cannelure, flat base w/ cannelure, and flat base w/o cannelure. My current A/R (Ruger MPR) loves all 3 with the same load: WW brass (size w/ RCBS X die), Federal 205 AR match primers, and a max load of H335, seated as long as a p-mag will allow. All three shoot near half inch for 5 shots at 100 yards.

That's good info. I believe I also had my best luck with H335. This was with the 55gr sp interlock bullet. Not a max load though, I believe I was a grain off of max in the Hornady manual. Ran BR4 primers because I had a bunch at the time, and I was trying to produce the most accurate load. 5 into around an inch was about the best I could muster in several AR's and a Ruger M77 varmint, and Ruger Hawkeye with 1 in 9" twist.. I went just the opposite direction as someone said, after that, and started loading the 53gr V-max for varmints and targets. This is, after all, the varmint rifle reloading forums.. With the 53gr V-max, I also had very good success with H335 powder. I'm still a little leery of that powder though, after guys like seafire say they blew up a rifle (or something to that effect) with it.. YMMV..
