Thanks Ruger7mm, that's an excellent article to read. For such a superlight hunting rifle that 10 shots group is more than impressive.

Update on the 284 project. Got some 6.5-284 brasses and loaded few rounds for ladder testing. I haven't fireformed them as now powder and brasses are very limited. Both loads are close to the land (haven't measured it yet). Below is the result:
2208 with 139 SST: 1,2 not measured. 3: 47 gr=2858; 47.5=2883; 48.0=2889
Hodgdon Superformance with 162 ELD-M: 53.0 gr=2696; 53.5=2686; 54=2763; 54.5=2767; 55=2817; 55.5=2868
Left is 139 SST, right is ELD-M

forgot to say the barrel is t3x factory, about 21 inches. In its previous life (7mm08) it loves 162 ELD-M and 150 ELD-X. I have loaded few 55gr H-SP and 160 ELD-M for a trip last weekend, and alas, gale force wind! Didn't get the chance to pull the trigger

I've ben following these threads on the 284 for while now and eventually got one myself. I've been playing around with superformance and this thread has been interesting. Im not loading myself for the rifle. I leave that to somebody with a lot more experience and expensive equipment.
The rifle is a T3 with a factory 7mm 08 barrel reamed out by gunworks. 18 inch with DPT suppressor and VX5 3 to 15.
using Norma factory 284 brass. 150 grn Nosler accubonds. Fed 210 primer and superformance we settled on 59.6 grms of powder. No pressure signs and shoots into .35 moa at a hundy. ran it over the Labradar this morning for an average of 2875 fps with an Es of 35. Conditions perfect at the range. Have shot gongs consistently out to 610 yrds with this load using applied ballistics.
Did have some trouble at first as the first chrono tried reckoned the load was doing 2840 and we kept shooting over top of the gong. We had to fudge to speed upwards to not shoot straight over the top of the gong. Two shooters and a change to a different scope to eliminate any random errors and variables kept coming up with the same result.
Have not had chance to go back out with today labradar data and shoot out again to see what happens.
Also worked up a load with win760 and 139 ssts. they shot very well but havent had a chance to shoot an animal with them and figured to accubond would be the load to play with for now.
Also had some old brass that came with the rifle of unknown history do have Mark Bridgeman have a look over it and clean it up and trim and resize. We tossed away some that looked tired or with split necks and did a experiment to see if we could find a load that shot the same POI at 50 mtrs for in the bush and that if i lost the brass in the heat of battle its not three dollar a pop brand new brass.
with zero load devolpment we loaded up three 139 grn Hornady interlocks (cos i had heaps lying around that came with the rifle) and went to the range. Norma brass 56 grns of 2209 and CCI primers shot at 50 mtrs on a wobbly rest on a windy day all shot within a 1 inch orange dot. I also ran these over the labradar today and these averaged 2912FPS but with a ES of 81 FPS.
I was happy with that so i have two loads that can be used interchangeably with no change to zero. The accubonds for the open long range stuff ( once i iron out the gremlins with the trajectory ) and a cheap and cheer full load to use in the bush and save the expensive brass and projectiles.
I've shot 4 deer with the new rifle and it has worked as it should, so much so that i sold the 308 and will try having one rifle to rule them all instead of the 7mm rem mag and a 308.
I also had a play at the range the other day with a mild load of 56.5 RL26 and 162 Eldx and 168 Berger's to see if they has potential. Both load shot into a ragged clover leaf with no fuss, so that might be the next development project over the winter when I have some time.

Thanks Blackfern, that's awesome load you got there. Hopefully I can go to the range to test/verify my loads this week.

Thank you Blackfern! I have managed get some 150 nosler accubond LR projects from here, and it is the ticket! my ladder testing shows 55.0 gr=2825 (cold/clean bore); 55.5=2831; 56.0=2905; 56.5=2930. 2&3&4 are about 0.6" at 100M. Very happy. Now I just need find more projectiles and the powder!

Good velocity for quite a bit less powder than I'm having to use. What barrel length and set up are you using?

Mine is the factory barrel length, around 21-22 inches.

I've just done a test run with RL16 pushing the 150gr eldx,
Started at 52.5gr and worked up in 0.5gr increments, the majic started at 53.5gr of powder at an avg of 2940fps, still have 54 an 54.5gr to try as I stopped at 53.5, not seeing pressure signs. 22 inch barrel. Happy as so far 0.465MOA

RE26 goes super well too, ive only tried it with 162's and 180's thou from my 22" 284 barrel

So I hear, been keeping an eye out for RL26 but it seems to as rare as unobtainium for the time being........ Sigh.

hi guys, im looking pretty hard at a 284 win tikka t3, is the 284 as good in the field as it looks on paper? i like the idea of sending a 139~154gn projectile with enough punch to anchor a reasonable sized red deer at 400 maybe 500 yards. a spot i shoot a bit often has animals around that distance across gullies

284Win will shoot that distance with enough energy to do what you need quite comfortably. The question is can you?

Absolutely. Choose the appropriate pill for the range & game you are intending to shoot & place the shot accurately = job done. I run a bush load (140gn Accubond or 145gn Speer HC) and 162 AMAX or ELDMS for 300+. In my 22in bbl 284 I get north of 3000fps running 162s with RL26. Who needs a REM mag?! Get 2950 fps with RL17.

thanks kiwijames & chainsaw, ive managed a couple of reds @ 316 & 383 yards with my 260 rem & 130gn gamechangers, recovered projectiles from both animals both high shoulder shots. my local farm property/ rifle range has enough flat area with a good backstop to shoot a 6in gong just on 4oo yards reasonably consistantly, ive just rejoined the deer stalkers after nearly 30 years so i now need to find out our local range days to see how i go from the 500 yard mound. i like my 260 for everything from magpies to deer but i thought a 284 might be a better longer range deer calibre, obviuosly a heavier projectile travelling a little faster has a knockdown advantage.
