Tikka T & Sako Gamehead ammo

[Gmm243]

Morning all,
Had reason to re-zero my rifle yesterday due ti the sling failing and the rifle falling off my back onto the lane. All was OK and zero had not moved thankfully.
My rifle is a Tikka T3 in .243 and I am using100gn Powershock with no issues. I also tried some 80gn yesterday and they were spot on as well. Due to not being able to get more Federal in 100gn locally I bought a box of Sako Gameheqd in 90gn as I had heard very good reports on them.
When I went to try them I could not get the bolt closed on them. I could chamber the round but the bolt handle would not go down. Strangely enough I think I had a box of these a few years ago which were fine but yesterday I could not close the bolt at all. I didn't force the issue so not sure how much pressure would have been needed to close the bolt but obviously more than I thought was sensible.
In all yesterday I tried 5 different weights of bullets from 4 different manufacturers and the Sako were the only ones that caused an issue.
Has anyone ever experienced this before?
Thanks.

I experienced it with some PPU ammo in an old T3 Lite which is apparently fairly common. I'm surprised Sako ammo would do it but would t be too concerned other than the cost of the ammo but you should be able to take it back.

I couldn't get the shop on the phone yesterday but it shouldn't be an issue to exchange.
I was surprised that the Sako ammo would cause an issue too and think that I had some before that never caused any problems.
I don't reload so have no way of ensuring cases etc to compare with the Federal ammo.

Bad batch of cases sounds like. Very unusual for Sako ammo as it’s normally spot on. Take it back explain and they will swap it.
