Is this hot for a .270? Newbie reloading advice.

Hi guys,

Im new to reloading and have recently developed a load for my .270win under the guidance of my brother. Just wanting your opinions because after having a look on the web I havent found any one else using as high a charge as me in this powder (wondering if my brother is as experienced as he makes out?.

Rifle: Sako A7 24inch barrel
Powder type: AR2209
Powder weight: 57.5 grains
Projectile: 130 grain hornady SST
MV: 3080 fps
Primer: Remington
Brass: Federal

We started the load ladder at 50 grains and worked up in 0.5 grain increments checking for pressure signs (there were non). Ended up finding a sweet spot in accuracy at 57.5gr and was happy with MV. What do you guys thing, max recommended load is 54-55.3 (depending on which book) so we are way over but no pressure signs at all.

Cheers,
Dawg

Quite a bit over recommended maximum load. Why go so far? I would be trying different options to get better grouping. i.e. bullet seating depth, different powder, different projectiles etc.  Huh
  

be good...And careful

Two grains over max charge does seem a lot but I've done it before, as long as there aren't any pressure signs.
In my opinion of course.

it all depends on the individual rifle......some long throated rifles can handle it hot and some tight chambered ones need it cold....... this is WHY reloading manuals say to ALWAYS start low and work your way up watching carefully for signs of pressure. once you KNOW your rifle inside and out you can cut corners somewhat as you have good idea where it will sit /like a load,whats fine in my rifle will blow up another...velocity isnt the be all and end all of everything. for years I used 130grn loads at mildish velocity as they were accurate and I didnt flinch....now with suppressor my loads are back to being hot and heavy pills get the nod too.....
a little faster and or a little heavier do kill a little quicker but shot placement is much much more important.
