Hello, Figured with the nice weather today I'd run out to the farm and shoot a bunch of reloads. Fire the 223 shots first, this was a follow up as all my initial loads came out hot (flat primer). Followed direction, started at minimum, but that's the way it goes. I ended up going with 26.0 gr of varget behind a 50 gr v-max and finally, no pressure signs (below start in my manual, hot batch of powder maybe?). 3 shots grouped at 0.49'' at 100 yards so I'm happy with how that worked out. Now to try long range testing. The 4-12x scope sure helps with shooting nice groups. For anyone interesting, best shot with the whitebox winchester stuff grouped around 0.8''. Not bad for a $300 savage ha ha.

The loads I'm interested in advice on were fired from my tikka in 270WSM. Here is the data (all 3 shot groups @ 100 yards), consider I'm firing 130 gr Barnes TSX 2.800 OAL and IMR 4350, wind was 15 km/hr in my face:

58.0 gr powder 0.842'' group
60.0 gr powder 1.020'' group
62.0 gr powder 0.946'' group No pressure signs, still a bit of room at top end.

Now, I am a hunter before a target shooter but I do love shooting way out there from time to time. Do you go with more powder (more velocity?) or better accuracy? I do not have a chronograph so guessing velocity by the book. Other factor here is my tikka only has a 3-9 scope so i can't shoot much tighter groups than that. What kind of accuracy do you look for in order to consider it a hunting rifle? How much should I try to bring the group size down? Chronograph would be nice for removing some doubt.

Had some 25-06 and 270 bullets to fire too but the wind picked up so I'm delayed on those for now. Will report back another day on that one.

My advice is free so take it for what it's worth. Lol.
I enjoy punching paper and looking at small groups , I also enjoy ringing gongs at a distance , with consistentcy be my biggest concern.  When it comes to a hunting rifle I'm happy with 1-1/2 moa if its consistent and the shooter is also consistent .  Moa or better is a no brainer as far as I'm concerned at most hunting yardages say <350 .  So as far as to stretching it out there  the question will be how far  do you feel comfortable and consistent at? Next question will be is the tsx or ttsx going to be effective at that range?  You'll want an impact velocity of around 2000 fps with a mono bullet. 
 If it were me I'd tweak your  62 gr load a bit with seating depth then stretch it out to 300 and see if your still moa or better.  And a chrono would be a big help if you plan on shooting much further then 300-350.  Much easier to find your drops with an actual muzzle velocity, also helps to insure your bullet will be in its proper operating parameters.
