Thread: Can you convert a t3 308 to 284?

If you Gunna go custom barrel better go for a 708 as I think you will get more $$$for it as a re sell

I have a t3 in 284win. Started life as a 7mm08. Sent to gunworks to rechamber the factory barrel at a cost of just $150.

It has the long mag and bolt stop. The barrel is chopped to 17" running a Dpt magnum suppressor. Doesn't need the magnum, but the magnum with more rear spacing brings the suppressor right back to the end of the foreend (which I like).

I run the 162g Amax at 2740 fps which holds 1000 ft lbs of energy to 800+ yards.

It is very accurate and Id happily shoot a deer at 600 yards with it. (Have shot 8 inch gongs at 640 yards).

It's now one of my favorite rifles as its a real 'do it all' rifle for me.

Mine was genuine too. What do other long action cartridges have over the 284?

Expensive brass, minimal factory ammo, kicks more than a 6.5mm alternative.

Arguably 6.5x55, 6.5 Creedmoor or .260 will suit that purpose better as they are all more than capable of 600 yards and more.
260 and 6.5x55 are available in all Tikka models from factory, and a few available in 6.5 Creedmoor.
6.5x55 has a lot of factory ammo available, and lots of brass available. The 6.5CM and 260 have Lapua brass that doesn't need to re resized unlike 284 (from 6.5-284).
260 and 6.5CM will fit a short action (not that you will save any weight using a Tikka T3), and all three kick less than a 284.

Nothing wrong with the 284 at all, but within 600yards there are plenty of caliber options that will do the job, even a standard 7mm08 will do that easily.

Yes those cals you mention can all perform well too, but the 284 works well for me in a short 17" barrel. I wanted to be suppressed but didn't want the total length including suppressor to be any longer than the factory 22" barrel. I think I'm at 21" total now.

And 284 with the 162g with the magnum suppressor is a real pussy to shoot too.

Yep I hear ya. A standard 708 t3 run as a long action running a 162g would easily do all he wants.

So would the 308

Most likely, but with more recoil, and 30 cal BC sucks arse ��

My experience is that the standard 6.5 chamberings can be slow killers at or over 400 yards. With a short barrel, more so. If I was often shooting 300 - 600 yds I would want something with a bit more oomph through a heavier bullet than 130-140 of the 6.5. An 18"-20" .284 and 160 grn bullet at 2,800 -2,900 fps will suit that nicely.

I've seen Craigc's .284 used enough to know I would prefer it at 400 yds to my 6.5.

Just this one boy's opinion though.

Information born of experience is the most valuable @Tahr. As as for opinion, that"s all any of us have to offer on such subjects.

I reamed a 7mm08 to 284, if your going custom barrel as others have said you would be better starting with a long action calibre
