The 284 win has a wider body case and a 308 sized base ( “rebated “).

Could be the T3 has a wide enough a action to run full magnums and WSMs. So people above have found them just fine with 284.

Yup the T3 action works perfectly with the 284w with no modification required. Really needs std LA mag and boltstop though to seat projectiles out far enough.

Both tack drivers but practically no difference at practical hunting ranges. That said I love the 284win, pretty much perfect all rounder in a lightweight rifle that you can spot your shots with and have enough wind bucking with VLD projectiles to be very effective at respectable ranges. It's my 0-600yrd rifle.

That's 7mm08 load must be farking hot

T3 with large action mag and long action bolt stop is all that is required....apart from chambering...

Nah mate, Hornady book lists 2800fps in 24" so less 100fps for 20" is about right. Brass lasts fine and GRT also suggests it's sensible. SF seems to be a big performance boost in this cartridge with heavies.

Been there done that.
7mm08 set up as long action, so I could use 160tmk or 162gr Amax worked a treat out to 600meters on game with a vx6 3-18, with alot less powder than my 284win

This might be a dumb question, changing a 7mm08, does that make it a 6.5x284 or a 7mmx284?
I'm in no rush just looking around at this point.

Cheers bevan

Unless you're going to start hand loading or have someone to load for you, changing to 284 would be pointless as I havnt seen any factory ammo available for years.

Interesting. I've struggled to break 2700 fps with a 22" Rem barrel and compressed Superformance loads.

Every rifle is different.

My mean velocity is 2690fps taken over >20shots with garmin xero. Tikka probably has longer throat than a rem. Load is at book max but seated long at 75mm coal, very close to 100% but not quite compressed.

284 is the ducks nuts on a Tikka. My one ran 162 ELDMs at 2600fps from a 17” barrel with AR2209 and 2700fps with Rel 17.
