Another 308 question

[TxxAgg]

I picked up a Tikka T3x 308 Compact. It'll get threaded. Do I keep it at 20" or chop to 16"?

I'm inclined to go 16"...but it sure does seems like those bullets leave slow.

Open to pointers. Let me know what yall think.

My 168 Speer Gold Dot out of my 16” barrel is at 2495 muzzle velocity.

I cut mine to 18” from 22”.
For me 20” wasn’t a big enough jump to justify at the time so I went to 18”.

For reference factory Norma 180 Bondstrikes have a MV of 2531 from the 18 and 4” of Tikka barrel weighs 4.6 ounces.

 

[The Guide]

What is your maximum range and what bullet weight do you plan to shoot? The research I've done shows that a 190 ABLR will still be at 1800 fps at 440 yards at sea level with a launch speed of above 2365 fps MV. The 308 can do that with a 190 but just barely. If you drop down to a 168 ELDM you need a MV of 2550 fps to get there. If you go down to a 130 TTSX Barnes you need 2925 fps MV just to get to 1800 fps at 440 yards which is below the suggested 2k fps minimum expansion velocity.

What bullet are you looking to shoot and to what distance?

I get 2585 muzzle velocity with the 168 ABLR. That puts me at over 1800 fps to 500 yards at 975 ft altitude.

Thanks guys. This is helpful.

This rifle isn't for a specific purpose...one of those "wants" rather than a need. Just seeing what the available options look like.

My brother bought one for his boys Christmas present . I had a guy cut it to 18” and thread it. Put a trijicon credo on it and screwed a silencerco scythe on her… man it’s a handy little gun. I sighted it in with 150gr fed fusions and the chrono showed they were like 2750ish

If you are putting a can on it, go 16”. If not… then keep it longer.
