Hi All,
Purchased a new T3X a couple months back and mounted a Vortex Crossfire ll 4-12 X 40 with Burris rings
Have tried 3 different ammo types so far and can't seem to get acceptable groups.
Hornady American Whitetail 150 grain
Hornady Custom 150 grain SST
Federal Premium 150 grain Nosler Ballistic Tip
So far I have fired the gun 21 times, only once did it display the gun I thought I was purchasing otherwise I am wondering if I need to try moving up to 165 grain ammo, keep trying different ammo or try a different scope?
Any help is appreciated.
Thank you,
JohnHi John – I compete with my T3X, in ISSF 300M competition, using metallic aperture sights. I handload my own ammunition, for the .308, and using a very “cookbook load” (read: common) via the AMU, has yielded great results:
a Sierra 168 HPBT #2200 bullet, seated to 2.775″, COAL
a Federal Case, trimmed to 2.005″, neck-turned .002″, flash holes deburred.
40.0 gr. of IMR-4895
a Federal 210M large rifle primer.From the 24″ Sporter barrel, this is driving the bullet almost right at 2500 FPS, dead even.
This load shot well enough that I was able to take the bronze medal, at the World Police & Fire Games, @ Camp Pendleton this year. The guy who took the gold, was the guy with whom I was sharing my rifle. You don't need to crimp the rounds (unless you like to), and the Tikka action feeds them well.
Federal brass is somewhat soft – so it stretches quite a bit. The neck turning and deburring ended up being key items – I shot the golf tee spotter three times in the 60 shot series.
I'm surprised that you didn't have great results with the Nosler ammunition – they are a reputable company, and their components are highly sought out by competitors.
If you're not a reloader, perhaps try some Black Hills brand, with the 168 gr. HPBT. The recoil is a slight increase from the 150's you've been using, but they are great in the wind, out to 700 yards.
Good luck!
