30-284

260 Rem · #1 05-09-2019, 05:00 PM

Anybody shooting 30-284? I am thinking of chambering one on a short action magazine fed hunting rig ... and of course there are “issues” that need to be overcome. If this was easy, everybody would be doing it

Input?

Exactly like a 30-06

On the left a 30-284 seated to COAL of 2.93
On the right 308 Win seated to COAL of 2.83
Bullet is Berger 168gr Classic Hunter
30-284 reamer has 0.070 Free Bore and the seat to the lands.

Just shove a reamer into one of your many .308 win barrels. Simple as that. The standard bolt face will work on the .284 just fine. I used a standard Winchester short action when I built my .284

I think those Winchester’s have longer magazine boxes?
No problem with the chamber job, I have access to the 30-284 reamer. Problem is getting it to feed from a SA magazine. I have two options: A single stack HS Precision detach magazine for which the max COAL can be 2.83”. Or, an extended Stiller box magazine (hinged floorplate) which will take the 2.93” COAL. At first blush, it looks like the latter sticks the longer bullet into the top of the chamber for a jamb... I suspect the case is not popping out soon enough because it is too long?

More tinkering and I am pretty sure the HS single stack magazine will feed with the COAL of 2.83”. The only “hunting” bullets I have are the Berger 168 CL/Htr and some 150 gr Nosler Partitions and they are seating (at 2.83) with the entire boat tail in the boiler room. That’s a bit more than I want so I need to look for a 30 cal / 150 gr hunting bullet with a tangent ogive short boat tail or flat base. Suggestions?

Perhaps old school, like a 150gr Speer Grand Slam...?

Those are definitely good game bullets with potential for a good “fit”. I did find some 150 Sierra Spitzer BT in my inventory that look like a decent fit.

Hornady makes a 150 grain SP and SPBT and a 165 grain SPBT. All three are relatively short bullets and are all good cup and core hunting bullets with decent B.C.

This is what I have come to the conclusion while working with 284 base cartridges . Single stack magazines work best . If not changing the magazine to single stack bending the magazine lips helps.
And lastly some times trying to get a gun to feed them can be extremely frustrating

may be some help here ..

I was reading this earlier this morning. Interesting stuff. It’s not exactly earth shattering and many guys are doing this already. But it is extremely nice to see a standardized option.

Absolutely it is ! I can see a couple of enhanced 06' chambers already.

Obviously, you're a disciple of Nathan Foster as well. One of the best out there imo.

At first blush, even the single stack magazine requires opening the lips to let the rim rise enough for the bolt to catch...and then as the cartridge moves forward and gets tipped up by the feed ramp ... the rim falls ... and the bolt wants to ride over the top. Makes me think of using my three lug Barnard SM action where the third lug runs between the magazine lips ...but that adds weight that I would rather put into the barrel. If I can keep the package to 8.5 lbs scoped, that muzzle is going to jump

You may have to change the feed angle.

I have one
Short action stiller, Krieger barrel, can’t remember what length
I could measure it if you like. One in 10 twist
Shoots a 178 eld at pretty close to what a 30-06 ai will.
Was using. R-26 for powder
I may have some info from some others if I look around

Hmmmm. Maybe you wanna buy mine.

Thanks Cheyenne ... I have more or less already “pulled the trigger”. Dies ordered from Sinclair / picking up brass from RPS tomorrow / will get a KSA barrel chambered with my buddies reamer with .330NK and .070 freebore. I already have the BAT action and will run two sets of bottom metal to be changed out depending on the choice of bullet. For long bullets I will run my Rem 700 hinged floorplate bottom metal with a Stiller extended length magazine box...or KSA bottom metal with a HS Precision detachable magazine for shorter bullets. I have a couple of stocks that are bedded to the BAT action including a Wildcat which should bring the scoped package to about 8 1/2 lbs. I considered a couple of options that would have shed a half pound, but I want a rig that is comfortable to shoot without excessive muzzle jump/recoil.

Wyatt makes the extended mag boxes. Many custom actions nowadays are machined for extended boxes....

Yes, I have one that I can use with hinged floor plate bottom metal ... will fit long pointy bullets if I decide to use them, which is unlikely. The reamer I am using has 0.070" free bore whch is best suited for bullets in the 150 gr range. However, many hunting bullets have a tangent ogive and for example: a 165 gr Sierra GameKing BTHP loads with a COAL of about 2.8" whch will feed fine from my HS Precsion detachable magazines. Not ideal, but I will need to deal with the fact BT junction seats below the NK/shoulder junction...which uses a bit of boiler room...probably not an issue with the 284 case capacity.
Ordered the barrel today, KSA 1:12 #4 to finish at 24" with MD about 0.70. Although I expect the scoped package to come in about 8.5 lbs, I anticipate recoil to be "lively" with some muzzle jump.
