I am looking into a 300 WSM barrel for my Tikka. I was wondering what are the heaviest bullets you guys are getting to run out of a factory Tikka barrel? I looked at Berger and it shows the 205 Elite Hunter would stabilize in the 1:11 twist. I saw Mountain Tactical Gen 2 Mags are supposed to run the WSM cartridges. So I figure I could load the heavies longer in the 300 with their mags.

The 205s will stabilize. I haven’t tried anything heavier - maybe some other folks will chime in with their experiences.

Hells Canyon also makes a WSM mag that’s pretty nice and that’s what I use.

Mine stabilized 200 gr ELDX but had some issues stabilizing 200 gr Terminal Ascent.

What would indicate stability issues? I've done a little reloading for 2 tikka 300 wsms with okayish accuracy. I'm re barreling one of them to a 1:9 twist. I've tried factory 200eldx, norma 180 Bondstrike. Reloaded 200.20x bergers and 175 TMK. Shooting at around 1000ft. Could just be the guy shooting.
Thanks.

2.5-3” groups and occasional keyholing. About 1 in 20 would impact slightly sideways. Wasn’t my loading either. It was factory ammo. I chalked it up to my barrel not liking that bullet construction with the mono front end and lead core in the base. The same barrel shot factory 200 gr ELDX into 0.3-0.5” five-round groups.

Thanks, I was getting decent groups with the occasional flier. I'm not sure if that's my shooting, my reloading, the bullet/gun combo, marginal stability, or ? I don't have any trouble reloading and easily getting the accuracy I'm looking for with my .223, 6mm and 6.5cm. There's a fella on this forum that claims people can't/don't shoot heavy recoiling guns as well and I think he may be right.

I don’t disagree with that fella, but my wizzum was definitely struggling with those bullets.

I'm running this exact combo. I'm having a little trouble with the spent cases ejecting fully out of the chamber unless I run the bolt really fast. Velocity is 2850 w/22" barrel.

Any of y’all running non lead in your tikka 300s. Not to hijack but I am curious if I can get decent accuracy from 165-180 copper bullets. Just picked up a tikka 300 WM and plan to play around with it.

That is good information to know. I had the same issue with my 7 saum as far as ejecting brass. If I tried to do it slow so I could grab the brass it would get hung up. So I just started running the bolt like I normally would and I never had any issues.

Ive reloaded for plenty of tikkas in 300win and short mag. All shot the barnes ttsx and lrx very well. All mag fed with quite long jumps
