Thread: 22" Barrel in 6.5-284 / .260

    22" Barrel in 6.5-284 / .260

    I am interested to hear from anyone who uses either of the above calibres in a rifle with no longer than a 22" barrel. In particular using 100grn or 120grn bullets.

    What velocity have you managed whilst retaining good accuracy and by using what powder. Not needing individual loads, just powders you eventually settled on as I will work up my own.

    I am considering one of the above in a custom build project in the future but do not need to use any heavier than the above bullets because of the applications in mind for the rifle. If needed I have a .308 for anything heavier anyway.

    Thanks in advance.

    The 260 in my gallery has a 23.5 inch barrel and I have homed in on N165 for the Hornady 129 gr SPs (2750 fps) for stalking and 140 gr AMax for practice. I have used N560 and RL-19 as well with the 129gr SPs and 129 gr SSTs, but the focus at the minute is the N165. No doubt at some point we will meet up and you can handle this rifle.

    Regards JCS

    My 260 has a 22" barrel 1:9 twist, gives 2895 fps with 120 Gn NPT using RL15. 7fps ES, with Nosler brass.

    20.5" barrel, again just short of 2900FPS with a 120gr NBT and 43.2gr Re17 or 40.5gr of Benchmark.

    If you are going shortish on the barrel, there is not a lot of point in the 284, you will just burn an extra 15gr's of powder for very little more velocity.

    Just because you are paranoid, doesn't mean they aren't out to get you......

    20" barrel on my 260 rem, using 43.5 gn of h4350 I am getting 2840fps with 120 barnes ttsx.

    Should have said, I was getting towards 3300fps with 100gr Hornady SPBT and 43-ish gr's of Benchmark. There were no pressure signs at all, but I thought it was too fast and backed off the powder. Accuracy was pretty good but I never used it on a deer.

    Jamross, bear in mind that according to the BR experts you won't get much more than 800 - 1000 rounds out of a 6.5x284 barrell! a .308 will serve you 5000+. not my experience, just throwing a thought in the mix that has stopped me from going down the 6.5x284 route, that's all.

    I could be wrong of course, have been many times before

    This isn't logical, but when did that matter with a new toy?

    If you want lighter short-action calibre in a standard (.308) size cartridge .... and already have a .308 ..... and prefer a 22" standard barrel length ..... then a .260 fits the bill.

    If you want a short-action, but in a large capacity (.284) size cartridge .... and prefer the same standard barrel length ..... and are shelling out for a custom-built rifle which can be in any chambering you fancy .... then go for the original .284 rather than a 6.5-284.

    This will give you the option of the lightweight 100gr and 120gr (7mm) bullets you want. In the larger bore you can also burn all the powder you can stuff in that short fat case in a 22" barrel length. Problem solved!

    just done a 6.5 -284 stalker with a 26 in barrel and it shoots 140 grns at 2920fps with h4350 and groups less than .2in @ 100yds and it will last 1500 -2000 rnds if its a staking rifle , if its a target rifle and rapid firing then yes it will last not much past 1000 rounds
    but that a lot of deer it would last most folks years ,22 in would give you about 2800 maby more but i think a 24-26 suits this cal best
    its a awsome deer rifle you wont regret it its mega accurate

    Now if I want one,,how should I go about justifying it to the plods?,,given .243 and .308 are already in place?? hhhmmm....what can it do that none of these can?

    excuse my ignorance, but the 6.5x284, is that a standard 6.5x55 action rebarreled to a .284? do any of the big aftermarket stock makers do these? (B&C, H&S, McM, etc.?)..

    now I'm starting to get intrigued!
