Home Forums Hunting & Shooting Hunting Rifles Do Tikka rifles cause velocity loss?

Ken, was the throat exceptionally long in your T3?

You know Tanner I can't recall how long it was but with OAL at mag length I wasn't touching the lands.

I wonder if that was the culprit. Did it seem like you ran into pressure while going slow, or could you have stepped on the gas?

I feel like sometimes book loads and QL are like Parlay, not rules, more like guidelines...

Okay that was dumb.

I stomped on the Magpro and other powders trying to best my .270 Win speeds.
I eventually did beat it by ~50-75 fps but I was at the very ragged edge with flattened primers and slightly sticky bolt lift.

In fairness, that particular .270 Win was exceptionally fast.

Very interesting. I guessed that most guys seeing anemic speeds were running low end charges, but I know you aren't one to do that...

Interesting I say!

Bingo....this can vary a bit even among barrels from the same maker,as no two barrels are precisely identical;internal dimensions,bore smoothness,number of lands, and condition are among those factors that play a role in delivered velocity.It has to do with the resistance the bullet encounters with its' passage down the bore.

Never owned one,but this is not unique to Tikka's.

Tikka owners with "slow" tubes should slug and measure their barrels.

There ya go ! !

Some yrs ago, a friend bought a brand new Ruger 77 7mm RM.

Believe me when I tell you WE swapped, checked, changed EVERY component over plenty of time.

That particular 7 RM would NOT beat 270W vel.
