6mm-284?


Registered Users do not see the above ad.


I have an opportunity to buy a 6mm-284. I can't seem to find brass for this gun.Is this something I would have to neck down from a 6.5-284 brass? What would be the best way to do this?

It is strictley a wildcat. You will have to make brass for that one.

You can neck down 6.5/284 brass fine by just running through the sizing die. But, you need to be sure the neck diameter doesn't get too thick for your chamber. Get the chamber cast if need be so you know for sure.

Often times the dies come with the gun when the gun is chambered for a wildcat cartridge. Ask the seller if dies, brass, and .... are included in the purchase.

Got one, and find the 6.5/284 brass is easy enough to size down to 6mm. I do it in increments and rotate the brass several times during the process so as not to crumple the shoulder.

The sizing down will normally increase neck length, so they will need to be checked for trimming afterwards. Also as mentioned, the necks should be checked to assure they aren't overly thick. An outside neck turner will be of benefit here.

love the cartridge in my customized P-17 Enfield. A little rough on the throat, so you don't want to over heat it during firing sessions. Using the 100 gr Hornady Interlock SP's and RL22 powder with standard LR primers, it is grouping sub-MOA.

Kdub,Is this a better choice than the 240 weatherby?I really like the 6mm round. What length is your brass? O.A. L.? How fast?

Depends on what you would define as a better choice.

You can purchase 240 Wthby ammo, whereas you would have to handload the 6mm/284.

For more powder usage the 240 Wthby will deliver an additional 100 fps over the top loads in the 6mm/284.

6mm/284 brass has a nominal length of 2.160" and a max length of 2.170". Since I merely neck size after the first fireforming for true chamber dimensions, the brass headspaces on the shoulder and really doesn't grow all that much, especially as I don't load over published maximums.

Also, I load for deer sized animal hunting and tend to use the heavier bullets - 95 gr to 105 gr. The above referenced 100 gr Hornady SP's are chronographing right at 3390 fps avg. This is using a 27" bbl.

The Sierra 5th handloading manual, 2nd edition, contains 6mm/284 loading data.

kdub, thanks for your good information. When sizing down 6.5/284 brass for the first time, do you use a full length die? I like the sound of this cartridge.

I use a neck sizing die for the first reduction, then I always full length resize brass the first time they are used - even factory brass. After FL sizing, they get trimmed to a common length, chamfered and the primer pocket/flashhole reamed (the flashhole gets inside reaming to assure no burrs).

A friend of mine has/had a Winchester 70 chambered for this one. We would snowmobile targets out across the cornfield then lay a tarp on a snow pile for a benchrest. It shot real well with his handloads for both of us. I remember he used 80 grain bullets but don't recall the powder or other data.
We would spot for each other and "hits" came easy out to near 500? yards.

I won't say that a 6mm/284 has any advantage over the other .243's, but it is a very fine round in my view. Just the fact that you have to "make your own" makes it attractive cartridge to me.
