So I have 2 each Sako 85 Long Actions.
One is a 30-06, the other a 9.3x62 (semi-custom).
I put in spent brass (ten pieces) and ejected in each rifle to see how often if any they ejected straight up into the scope.
The 30-06 did eject at around 85 degrees twice, but the rest ejected at around 75 degrees. This wasn't so much of an issue because the lip of the neck brass was hitting the round part of the scope so it simply bounced out.
The 9.3x62 on the other hand ejected 2 at 90 degrees, and 2 at 85 degrees, the rest came out around 75 degrees. This is more of a problem for the 9.3x62 because the turret block of the scope is where the lip of the neck brass is making contact and it's flat so brass can rebound back into the open action.
I removed the springs and examined the extractors.
The O6 spring was stronger than the 9.3x62 spring.
I also found the 06 extractor groove was nice and sharp and clean, the 9.3 had a brass shaving in it with some junk.
I tried putting in the "Gre-Tan" Sako Replacement Springs to find they bottomed out when trying to re-install the extractor due to them being longer and not compressing enough to clear.
I experimented a bit and found out you can cut off .75 coils and get the bolt back together, and functioning. The extractor "grab" is significantly increased from the factory spring feel..
Long story short both are ejecting at 70-75 degrees now...
I'm kind of astonished, I didn't think it would be that consistent.
So lesson's learned - make darn sure you inspect your extractor claw for any shavings. And replace your stock spring with a stronger one. I do think that if your extractor is warn, or rounded that this wouldn't work as good...
The fix cost about a dollar!! not including postage.
Anyway - that's my experience.
Best Regards,
Spot
