New Tikka T3x Roughtech Ember and issue with Hornady Superformance ammo

[JimLob65]

Picked up a new Tikka T3x Roughtech Ember in .243 Win this weekend to go with the T3x Roughtech Desert Tan in .270 Win that I had won at a raffle earlier in the year.

The actual rifle that I had won was in .300 Win Mag, but I have no need, desire or shoulder for that round. Decided I would like to have a modern bolt action rifle in a ‘big game’ caliber and the .270 was available. I really like it. Very smooth and accurate and a great trigger. BTW I also bought a T1x in 22lr at about the same time.

I decided I would like a lighter centerfire caliber to shoot as I find it more pleasant to shoot a lighter cartridge as I get older. Found this rifle at Jays Sporting Goods in Clare and picked it up. It shares the same attributes as the .270 and I am very happy with it.

However I did have some issues with the Hornady Superformance 95gr ammo. Some rounds chambered fine, some required a bit of effort to close the bolt and two rounds absolutely refused to chamber at all! Has anyone experienced this type of issue with Hornady Superformance ammo? I racked all 20 rounds of Remington Core Lokt 95gr ammo through the Tikka without an issue

Got some calipers handy?

Tikka mags are, notoriously, a few years behind the curve for a lot of the modern bullets that have a great OAL than previous generations of loads.

I know my .308 mags are getting notched from the nose and I’ve heard the same from guys with the .300 Win models.

However, this is purely cosmetic and cycling off-the-shelf ammo has been fine.

I had absolutely no issues feeding from the mag. Rounds slid into the chamber like butter. The issue was that the bolt won’t close on the rounds, or that the bolt required extra effort. It is almost as if the rounds were too long for the chamber.

(Note that I don't have direct experience with that rifle, or with Hornady ammo.) Here are some general comments:

I advise against firing ammo that is difficult to chamber. Given that it's a new rifle, carbon fouling isn't a likely explanation. Leaves two obvious explanations: 1) Your chamber is out of spec. or 2) Something's wrong with the Hornady ammo. I think door number 2 is most likely given the inconsistency of chambering. If it were your gun, rounds would either fit or not. I'd try to get ahold of some other ammo to test that hypothesis. You could also buy a pair of go/no-go gauges to check the rifle.

I have not been favorably impressed with either accuracy or velocity of Superformance factory ammo in 338 Winchester Magnum and 30-06.

T3Xs usually come correct from the factory, so I'd try different ammo.

Thanks for the reply. From all appearances it seems to be an issue of tolerance stacking, with a tight chamber and ammo approaching or possibly exceeding max length. I had heard elsewhere that someone had a similar results with Winchester Silvertip ammo, so I don't appear to be a lone voice in the wilderness. I don't plan on shooting any more Superformance ammo through it, or any of my other rifles going forward. I bought what was available at the time, and generally like Hornady ammo. Lesson learned!

Although I generally like Hornady ammo this is the first, and most likely last time buying Superformance ammo. It was too darn expensive to have to discard 10% of it as unusable. I actually didn't realize it was in fact Superformance ammo until after I bought it! I will certainly pay more attention in the future.

Tight chamber: This could be the case, but wouldn't explain why supposedly high quality factory cases vary in whether they will chamber. Good ammo should have the same head-to-shoulder length, and every case should either chamber or not chamber.

Ammo exceeding max length: This could be a headspace issue, not strictly speaking a tight chamber. Do your 'hard to chamber' rounds have a circular mark at the ogive of the bullet? You can test this using a sharpie. Blacked the entire bullet. Attempt to chamber. Look for mark indicating that the bullet is hitting the lands of the barrel.

If it's not consistent, it's not quality ammo.

Given that the headspace is constant and does not vary shot to shot and that many rounds of the Hornady chambered just fine it would indicate the ammunition is the variable in the equation. Ditto given that all the Remington chambered just fine. Obviously there is some variation in the rounds contained in the box I purchased as many fed fine, some were tight and a couple wouldn’t allow the bolt to close at all. Maybe a Friday batch?? Who knows?

Several of my hunting companions used Hornady Superperformance cartridges, which ended when they found that the casing separated from the core on impact with a buck. They've switched to Norma, I prefer Hornady, but in the more conservative, lower velocity and vetted Interlock configuration.

Best, Jon

Thanks for the reply! I don't see ever buying that type of ammo in the future for any of my rifles. As I think I stated above I didn't realize I was buying Superformance when I selected it. Were I ever to deer hunt I would choose some other kind of ammo, or maybe take my T3x in 270 in which I have been shooting Norma ammo BTW.

[JimLob65]

I bought a box of 100gr Norma Whitetail and racked a few rounds through the new Tikka with no issues. Further reinforcers the notion that the Hornady ammo was the cause of my problems.

I would also bet on door number 2 as the place to start checking things. I've experienced exactly this issue in a Tikka rifle with other Hornady factory "match" loads in 6.5 CM. Other brands, no problem. Not even all Hornady ammo caused a problem. If you look around over on the Hide, there's been known issues of this happening with Hornady ammo.

Thanks for the reply! This is exactly what I was looking for. I have also heard one shooter has had the same problem with Winchester silvertip ammo in his Tikka. I really love the rifle but have minimal chance to shoot it. Once I settle on an ammo I suspect that I won't have this type of thing pop up again.

I just now am seeing this thread and see that you have received some very solid advice. Tikka builds some very consistent rifles, so opting for some different ammo was a good call. My experience with Hornady ammo has been generally positive, but the superformance line was not in that category when it came to accuracy, though my experimenting with it is from a few years back and I would consider the info not to be current in terms of relevant data.
