.270 wsm loading help

RL-26 got the fastest velocity ( 3,300 ish) for Robbie Denning over on, the Rokslide forum, using 140 Berger, Classic Hunters, can't remember how much powder, tho. The Data is avail from Berger for, several Powders so check their load Data. I use 64.7 grains of IMR 7828 w/ F-215's using, the 140 AccuBond's at 3,140-3,150 FPS ( it's a very accurate load, in my Tikka, T3, SS lite, 24" .270 WSM @ easily under, MOA ) it's not, a max load (1-2 grains, short of Max) per Berger and the IMR Data on Hogdon's powder site BUT, use Caution as always, when "working up" loads !
She went "Boom" in 15-20* weather, last week in Arizona,.. killed my Elk !

Good job on elk. I'm getting same results with 65.5 gr of RL19 with 140 accu bonds at 3150. My shot grouping is 3 in a quarter but I really think I can do better. Just haven't found the magic recipe. My daughter and I are shooting model 700's in stainless. My kid brothers tikka however is painting a dime with these loads
 
I found my reloading Data and saw that, Robbie Denning was using, 67 grains of RL-26 per my old notes ( 68 gr's was too Hot for, his Rifle ! ) and he was getting 3,357 FPS out of HIS Gun with, the 140 Berger's ( NOTE: the Berger Bullet has a SHORTER Bearing surface than, the 140 AccuBond, THUS, the higher Velocity, possibly ? ) His gun was a 26" bbl. Christiansen Arms Rifle, I believe. The Berger Data shows, 68.2 of RL-26 as Max and 3,184 FPS for Velocity,.. considerably less than Robbie's Chrono'd results ? Possibly a "fast" barrel or, bad chrono reading's ??? I do know that, RL-26 is serious, "Pixie Dust", in some Guns ! I already had, 3+ pounds of, IMR 7828 left over from, a 7mm Rem Mag. that, I had sold and my son thought that, I should try it first.
Always work up loads carefully, as my load ( 64.7 grs IMR 7828 ) is a grain or so, under a couple of "sources" data, but is way over, Nosler's Load Data ! It is a SAFE load in MY Tikka, But at 65+ grains,.. pressure was starting to "show" and groups, opened up ! I have shot several 1 1/4 to 1 3/8 inch, 200 Yard, groups, so I am very happy with, this load. I polished my Bore and Throat with, JB's slathered on, a bronze brush, w/patch, when gun bbl was New and now, it cleans easily, looks like a Chromed Bore, as it's so shiny. The Tikka's have, quite long throat's and the AccuBond seems to like to "Jump" a bit ! You might try different seat depths ? Is your barrel good and clean, "Free floated" & Recoil Lug "bedded" ? Good luck with, your loads / Rifle and stay SAFE !

Thank you fir that. Pressures are a valid consideration, I've gotten a bit hot on occasion. I'm having a 6.5/284 Norma built as we speak and plan to start with RL26 and Retumbo. Both appear to be fine fir my .270 and i will try them. But I am really hoping to get H1000 working. I've always had great success with it in my .30 caliber magnums . Thanks again
