Thread: Short barreled 6.5-284

Could go 284 but already have 280ai which would pretty much be the same thing. Looking to do something different hence the short barreled 6.5-284. Could go creedmoor but the 6.5-284 has a greater case capacity which I would assume would lead to increased velocity as appose to the creedmoor. 6.5x55 is another good option tho! More just after anyone who has a short barreled 6.5-284 or even 6.5x55 to see what sort of speeds one could expect from the shorter barrels..

@25 /08 IMP mostly wrote the answer to your question based on his experience:

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 speed I thought I should.
I now have a .260... as I can get 2880 fs from a 20" and 2810fps from my son in-law 18" and the (6.5x)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.

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.

Were you using straight 260 or ai?

He's had both the speeds he is mentioning their are 260 143 eldx and 142 lrab I imagine . A buddy's just sold his 6.5x55 that was 140sst doing 2650 2209 I believe.

nice way to pass the time wondering what cartridge to go for. Straight 284 be similar but different application and prolly be a good 200 to 300fps behind your full length 280ai?

30/284? Would make use of the short barrel nicely I would think.

I've had both but now use .260 you do get a bit more speed from the AI but at best 100fps maybe less and then there is the mucking around of fire forming.
Just stick to a standard 20" .260 or Creedmoor

30/284 would be an interesting one, should go really well in the shorter barrel too.

Go the 260, @superdiver had one that performed really well with a short barrel. So do a few others. The 6.5x284 doesnt tend to respond well to the chop. You could go 30/284 which has been done here but then you could also chop a 300wsm and put a can on it, or a 300saum if you like wild cats. Both known to respond well to short barrels, and then youd still have an extremely capable rifle down range. I'm currently taking the alternative route and building a 24" 284 to try and chase every last fps out of the cartridge. (But that's just me) alot of guys like the bush pig style of rifle and they serve a purpose. At the end of the day everyone will have an opinion, trust your gut and enjoy it

This might sound a bit boring but the the good old 308 goes good short. At 16 inches I have shot 2 goats with one shot @450 yards. 18 inches 650 yards is no problem to drop an animal with a 168 eldm
Depending on what the goal is?

What about a 6.5 PRC? Is that not basically a magnum version of a 6.5 creeedmore?

Had 2x death machines now(18" bbl 260). Both chucked 140eldms @ 2730-2770 with 43.5gr-45.5gr 2209. Both are owned by other forum members now and I doubt they would sell them back or on as they were good to 750yds~ on a red deer sized animal. Don't overcomplicate things trust me

Yip you are right you won't be getting that 18".260 back, mind you nor will I now my son in-law has it.

Go for it man. Variety is the spice of life. With the heavier bullets you absolutley will get better velocity than a 6.5 creed or 260. It's just physics.

I would be looking at rl16 as a good powder to work with

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

I've had a 16" barreled 6.5x284 for 6 years now its my go to rifle, have shot 4 nice 8 point Sika with it. 143gn ELDs at 2750fps 130gn ABs at 2800fps consistently groups 1/2, far more efficient than my18" 6.5 Creedmoor

A 18" .260 will more than equal those speeds and I'm picking with less powder as well.
