6.5x284 in short action

Will a 6.5x284 work in a Rem. 700 SA? Or should I be looking for a long action for it. Also if you guys remember savage use to chamber the 112v in 220 swift in a long action. Would it be better to use a long action with a #7lv barrel in any caliber than a short action for the leverage it would give or would it flex more that a short action? Do you get what I am talking about? If I float the barrel it is just hanging out there on a small amount of threads the 700 has. Seams like it would piviot less on the front of the action with a long action.
 
Magazine length is your only worry... as a single shot no problems at all. The thread size and length is the same on both actions and you can hang big barrels on them.

With my reamer freebore, that has a 142 smk touching the lands, a loaded round will not eject from a short action without removing the bolt. A shorter freebore or remove the bolt, and it's ok.

I have built 2 on long actions, with pillars and epoxy bed, floated, one HV and one #7 Krieger.

Call Dave Kiff and ask him about a short throat 6.5x284 reamer. It would then work with a Short Action.

short action

I have built several Rem short actions using the 284 parent case
6-284, 25 284 ,6.5 -284 and 284.If you are trying to build a repeater make a dummy with the bullet you want to use that fits the mag box and have the reamer ground accordingly.

Several years ago I had a long conversation with the folks at Montana Arms about and action for this same situation. The listened and produce and action just for your needs. A little longer than a short action and shorter than a standard action. Lets you seat bullets long to chase a worn throat and still feed through the magazine. What with the popularity of the .284 and it's many off springs, this is a natural for all but competitive shooters.:D

Not used by competitive shooters? I've seen several in the 600 yard BR game and there is quite a bit of usage in F-class and 1000 yard.

BTW, the 284 Winchester was designed for short actions, originally the Winchester models 88 and 100 that were designed around the 308 case (243, 308 and 358 Winchester)
 
Not with VLD bullets

If you will measure a loaded round with a VLD type bullet in it (I used a 130 Norma for example) you will find that it is considerably longer than the 2.8" magazine box on a typical short action 700.

If you want to use a short action, you will be relegated to bullets light enough to be seated short overall.

You can't seat the 140 VLD type bullets deep enough as the tapered part of the bullet will project into the case mouth leaving the edge of neck brass exposed to hang up and collect debris.

You also cannot eject a loaded round should you decide to use it as a single shot. In short, I can't see a good reason to try and do such a thing.
 
6.5-284 in Rem Short Action

Brownells sells an extended magazine box (Made by Wyatt) for short action 700s that increases the magazine length to around 3 inches or a little more. It requires some modification to the receiver, but is not difficult to install. Works well with the 6.5-284 in a rifle with the chamber throat set up for 120 grain hunting bullets. The longer 142s would still need to be seated way down in the case even with the 3 inch mag. Incidentally, Jerry stiller's Predator short actions are cut for the Wyatt magazine box.

Again- a tremendous amount of work for what? It is really a "medium" action at this point and still cannot eject live round and seat 140s to a necessary length. It's not really worth it IMO

That I did not know! I had it in mind that few people stepped outside of the Remington or clone safety net.

Yes Jerry, it was designed around the use in those actions, they never knew about latter use of the .284Win and VLD bullets and it's many step children, or did hey?

If you are one of the people that chase a worn throat in a barrel and have to progressively chase the lands, a short action leaves you with squat. That was my original thoughts when I proposed a slight increase in the length of the action.
 
Why use a 6.5X284 in a short action? You might get a little longer mag box, but the ejection port is still too short. If you get a short throat reamer, you are defeating your purpose. You will be pushing your bullets way back in the case or you will be using small short bullets. You might as well go to a 260 and eliminate those problems. I don't think you are giving up much with the 260.

I have a short action 700 in 6.5 x 55. My smith modified my bolt stop so that I can eject a loaded round with 142gr Match King loaded at 3.062. The rounds can be single loaded from the mag and ejected if not fired without removing the bolt.

Agreed..

6,5x284 is best in a long 700, or custom action. The Lapua Brass is what gives it the edge over the 260 I think. But the 260 is a great round also.

142 sierra matchking or 140 VLD on the lands, 51gr H4831.

Amazing cartridge.

And the fact that the 6.5/284 having 66 grain water capacity and the 260 Rem only having 53.5 grains water capacity is not a factor in the 6.5/284 popularity for 600/000 yard benchrest???

Yes, the 260 Rem is a good cartridge and I think I know the guy who designed it but it is not ballistically superior to the 6.5/284.

Actually Butch, Greg McGee (old-time IBS 1,000 yard Shooter of the Year & Nat. Champ) use to use a short action with a .300 Weatherby. Single shot, of course. Might also have to use a different, BR-type bolt stop, I can't remember. Clay Spenser smithed his rifles.
 
Charles,
I don't believe that I said it couldn't be done. I just stated why I wouldn't. Now that being said, I don't care where you put the boltstop, it won't eject a loaded round out the port.
If he cares to deal with that, He needs to go for it, but at least he knows what he is up against.

Yeah...the 3k/sec accuracy node and all that...voodoo stuff. The 6,5x55 is also a great round, and ....good brass is available.

Is ballistic superiority (faster) always better? why not the 264 win mag or 6.5 rem mag?...again, I think it's brass that sells it.

2 weekends ago I shot a .9" 5 shot group at 424 yards with a 6.5x284, then my friend picked up the rifle and did the same, with one round out 1.5"

This is a no turn neck reamed rifle, .002 neck clearance.... Lapua brass, Krieger 8 twist #7 ctr.
 
I agree with Butch wholeheartedly. Just two months (or a little more?) ago I chambered up a 6.5-284 and screwed it onto a Rem short action....never again. WHAT A PITA! With Berger 140's I couldn't seat out far enough for magazine feed (obviously), but ALSO the SOB's wouldn't eject. The tip of EVERY bullet would hang on the edge of the ejection port and I'd have to dink around with the bolt release and the round to get each one out.

I said to hell with that, took the barrel off, and chambered one up in 6.5X47 Lapua and life is good again....at least less stressfull anyway.
