Thread: Short barreled 6.5-284

Anyone had experience using a short barreled 6.5-284? Thinking 18” using 140eldms. I see people on here getting mean results from the short barreled 284 so maybe someone has done the 6.5 aswell?

Yep a few people have tried a short barrel 6.5-284......

Its a waste of time, better off running an 18" 6.5CM id say.

PRC goes good @20 inches.
A mate of mine runs the 6.5 284 @20 inches, I think he is getting around the 2940fps with 140 bergers

Yea thought about the creed but building it on a sako Av so waste of a long action doing the creed. Other option could be 6.5-06 or ai version

6.5-06 or AI is still the 6.5-284 ballistics/case capacity....really no difference.
If you want a 6.5mm stick with the 6.5-284 but in at least a 22" barrel.
If you want a 6.5mm in an 18" bbl, then do what GWH recommends and use a 6.5 Creedmoor...just seat the 147gr ELD-M out right out (get the reamer in 6.5 Creed with a long throat).

I've done most over the years 6.5/06 and the AI version also 6.5x 284 which I think was either a 18 or 20" I'm not sure.
I really struggled to get the seed I thought I should.
I now have a .260 which is the way I would go it's even better on a long action as you can seat the long 143 or 147 way out.
The Creedmoor is a good option but I would still go .260 as I can get 2880 fs from a 20" and 2810fps from my son in-law 18" and the 284 I had only just made it over 2800 with the 130 Nosler AB although that was with 2217 and it probably would have gone better with RL26.

Mate's one was 20" and he was getting 2750 fps not trying too hard with 140 grainers.

6.5x284 .... great 6.5 round but would be totally counter productive to then chop the bbl ?? As others have said if you must have short bbl then go Crudmore or 260

260 Improved 30° maybe @Uplandstalker @Mathias ???

Though if you've got the long action to play with a 6.5*55 or the BJAI version?!? Relatively cheap Lapua brass for the reliable old Swede or its' hot-rodded brethren?

260imp 30, issue is dies. Guy in the US that has them is hopeless to deal with.
Long action...go the 6.5x55

No experience in the 284 but have a 16" 6.5 Creedmoor and love it. About 2500 ft/s with a 129gr projectile and a mild load of 2209. Around 2700 ft/s doable with a 120gr pill and factory ammo was doing 2600 ft/s with a 129gr SST. If you want more speed, RL17 is something to look at which I will in the future.

The 120gr pill out of a 16" 6.5CM barrel gives you literally the same ballistics as a 175gr pill coming out of a 22" 308 barrel within 1000m...

Yeah....... but which one is gonna hit you harder?

If you have a long action I would rather go 6.5x55AI. Cheap lapua brass too.

Why not just go .284?

The .308 by around 100% BUT irrelevant as you, Antwalsh and I are smart enough not to try to shoot anything living at that distance
