Thread: Reinventing the .284 wheel

Got my hands on a T3 7mm08 today, to replace the 308 I'm going to sell. Plan is to get it going as is for now, then turn it into a compact .284Win, so:
1 - Who is getting what velocities and results with what powders and projectiles in 7mm08?
2 - Who has got the pro tips on 284Win built on a T3?

I have on hand at the mo Norma cases and 120 Bt's and 120 Sierra Gk's so will start there.

@GWH . As far as 284 results go his are bloody impressive

I ran 2209 and 2208 between 162eldms, 154ssts, 150sgks and 145hcsp. Rifle was an all rounder so figured with reasonable speed and the good bc of 7mm pills I could get away 0-500m with most. I found around 53.5gr-54gr of 2209 with a 150gr~ and a 19" barrel gave good accuracy and 2700fps+. If I had my time again for an all-rounder I would probably use a 160gr~ soft point

@Noswal tell him about your performance and hunting results with 162s from your 22" 708.

2208 or RL16 work great in 7mm08. I’ve settled on 150eldx in front of RL16 at 2750fps as do everything 0-500 yard combo

I'm currently farting around with a 708 downloaded with a red dot sight.
When it come time to get it cooking I'm undecided on whether to AI it and run 150s or 284 it and run 162s.
Shorter and supressed or factory length and bare is another thing I wax and wane over

RL17 and 162 ELD-M at 2630fps out of 20" barrel. Enough horsepower out to further than I would shoot.

If we are re inventing the 284 how about necking up a 6.5 PRC to 7mm would be similar /better? and would fit short actions and more rifles

Im loading my 7-08 with 162gr Eld-m, 46gr of 2209 (it is a little compressed) I'm shooting a Blaser so am able to seat quite long 2.924in achieving 2675fps
Have taken a Spiker at 590yds and Tahr x2 at 680yds (575tbr)
I've rung steel out to 1000yds with this load putting a 4in 2 shot group.
There may be more suitable powders like 2208 for example but why fix what isn't broke

What length barrel @Noswai ?
Sounds like a good load

I think you'll find that's something that's been around for quite a long time now ...... aka 7mmSAUM

I'm getting 2900FPS out of a 22" weatherby ultralight pushing 139gr SSTs
Using 2208 at max book value, think it was 43.5gr

Thats from a 22in standard Blaser barrel @winaa
I wanted a load that was capable of taking deer at 600yds and I'm confident this load in my rifle will do that comfortably

Thanks

Getting 2900fps out of a 18inch model 700, 2206H powder and 120 nosler bt
