Re: 270WSM which powder?
I have a Sako75-stainless .270WSM and theese are my (personal) best loads:
- H4831 x 65.00 grs.
- Accubond 130 grs.
- Remington case
- 73.00 mm. Hoal
- 3.000 fps.
note: this is not a very fast load ... but i had the best accuracy ... Roe-deer go down "frozen" ! .. with this load i had average 0.43" on 3 rounds (at 185 yds. ... i have max. this distance in my shooting range)
With the same components and data, changing only the bullet (Sierra MK135 grs. hpbt), i had the best accuracy 0.32"- 3 rounds at 185 yds. with less speed (2.960) ... but i never shoot SierraMK in Hunting action, only to the paper-target.
.. I used the Accubond130 in Hungary, last winter, there was -10° outside ... absolutely no problems ! ..(4 Roe-Deer, from min. distance 165 yds. to max. distance 285 yds.) .. standing erect, helping by a three ... or sitting with the rifle on the back-pack ... believe me is not easy ...
This is my little experience, .... hope this help.
Shoot slow, do everything else fast.
