I recently purchased a TIKKA T3 in a 270WSM. I took it out to play with it and had some factory 150 Fed Premium Vital Shocks. First 2 shots sighting it in then 5 in 1 ragged hole so I was pretty excited. Started working up loads for it the next day. Loaded up 3 bullets each of Berger 150's pushed by 60-64 grains of RL22. No preasure signs at all but groups were over 1.5" Also used 61-65 grains H1000 with no signs of preasure but groups again above 1". I am limited to mag length so I have quite a jump with Bergers so I figured I would give the 140 Accubonds a shot. I loaded these with 60-64 of RL19 60-64 of RL22 and 63-67 of H1000. None shot inside of 1.5" and no preasure signs at all. I didn't figure I would see any preasure signs with these loads but I stayed off the high to get a feel for the gun. Last 3 shots 150 Fed Premium Vital Shocks in ragged hole. Hmmmmm. Today I decide to open up a couple federals to see what the powder charge weight in at and what type they use. Usually I look at if its Spherical or Extruded and the weight then go trough the manuals to find a known spherical or extruded around that weight First one I opened up Spherical 77 grains, 2nd exactly the same. I am floored by this. Does that not seem like a **** ton of powder? I cant find a single load in a manual close to that nor can I find a post. Velocities are published at 3160 if I recall. Normally I take that with a grain of salt but I am thinking with 77 grains of course it is. What kind of powder could this be?
