30-06 or 6mm-284 ?
« on: August 12, 2009, 02:05:39 AM »
Okay.  I've posted elsewhere about a member of our club needing to sell a Walther PPK at the swap meet we held this last weekend.  The primary impetus for the swap meet was one of our members has terminal cancer, and he donated all his guns and reloading equipment to the club, with the proceeds to go toward purchase of an electronic access gate.

This particular member is a retired engineer, and a pretty fair gunsmith.

Among other things, I bought a 30-06 he had just finished built on a K98 Mauser action (WWII bringback by his uncle).  It hadn't even been test fired yet (though that was remedied Sunday).  He didn't like the look of the fired cases, so he gave me back my check and took the rifle home to take the barrel off and check all the dimensions.  Possibly polish up the chamber.  When I talked to him this evening, he said he recalled that I might have mentioned that I already had a .308 (I do).  Since I do, and the 30-06 would be somewhat redundant, he asked if I might be interested in a 6mm-284 varmint rifle in place of the 30-06.  Same $$.

As I mentioned, I don't need the 30-06, but I have probably 400 rounds of brass for it, so that was a consideration for wanting one.  (I have at least a thousand 223/5.56 cases as well, without a gun - yet, but that's a different topic.)

Anyway, I'll call him Friday to discuss his findings on the 30-06.  If it cleans up okay, should I go for the 6mm-284 anyway, or stick with the 30-06 (which had the most awesome trigger I've ever pulled)?

  What would you be using the gun for and where do you live?

6MM-.284 is interesting, but really after looking close at it you'll see it barely does much more than 6mm Remington, which is a factory load and cases are cheap.
Cases for 6mm-.284 aren't cheap, even when formed from fresh .284 cases.
Obviously you will have to reload for the 6mm-.284.

Look at it from the ammo side .30-06 will be much easier to get ahold of. Besides I couldn't give up my -06. Your choice though.

If reloading for a wildcat isn't a problem (does the 6mm-284 include dies?) and you've already got a 308 you're happy with, I'd go with whichever rifle is more personally interesting (which is completely subjective).

LL - You mean I have to have a purpose for it?   :hmm  I'd like to hunt sage rats over in eastern Oregon (Belden's ground squirrels - similar in damage here to your prairie dogs).

Randy - he doesn't have a 6mm Remington, just the 6mm-284, so my choices are limited to what he has.  The proceeds go to the gate fund, so I'm not looking to buy elsewhere just for the sake of getting a new rifle. 

GD - I understand that you couldn't give up your 30-06.  But I don't have one (yet), so I'm not really giving up anything.  My wife doesn't hunt, and if she were to start, I doubt it would be with either a 308 or an '06.  Too much kick.  And I may eventually inherit my dad's 30-06.

Jesse - He's got the dies, so I should be able to either get them with the gun, or buy them separately.

Now, if I could get her into sage rat hunting, she could use my .17 HMR, which has virtually no kick, and I could use the 6mm-284.  So there's a plus for the wildcat.  Of course, Randy brought up a good minus.

Please keep the opinions coming.

It's supposed to be one of the flattest shooting rounds out there, so for varmints, that's good.  I just don't hunt varmints that much.  Yet.

  Are you set up for reloading (it looks like you are)?  Go for it.  That round is a coyote widow maker.

I have to admit, I'm leaning toward the 30-06.  At least slightly.  That way my dad's '06 can go to my older brother. 

It really depends on what he finds when he pulls the barrel.

I didn't want to rain on your parade, just be realistic, but if you reload that 6mm-284 can be pretty interesting. I like 6mms quite a bit (<-understatement),
my first deer, prairie dog, and woodchuck were all shot with the .243. (In a couple of different rifles.)
Anything .243 can do 6mm-.284 can do in spades. It and it's close ballistic mates the .240 Weatherby and the 6mm-06 wildcat are very similar. All are really more of large varmint/deer calibers than pure varmint cartridges, and really shine with heavier bullet weights versus the .243.
But they will launch the mid-weight varmint bullets far and fast enough to give even the hottest .22 centerfires a run for their money.

The 6-284 can be finicky to load.  It also burns up throats pretty fast. 
When a .243 throat goes you can rechamber, but to what do you rechamber a 6-284?

You could always just pull off the barrel, cut the shoulder back a thread, and recut the 6mm-284 chamber.

That's true for a Heavy/Bull barrel, but is that doable on light barrels?, those where the chamber is a bit more robust than the rest of the barrel.

cpaspr, what kind of barrel is the "Varmint" installed on the 6mm-284, I'm always curious regrading barrel modifications  ;D

I haven't seen it, other than just in passing a couple of weeks ago when it was being assembled, but he said it was a fluted barrel (which I actually do recall).

And just to throw another potential monkey wrench into the pot, when we talked a couple days ago he said something about how he may have modified/wanted to modify it somewhat to reduce pressure and extend the life of the barrel.  Sounds like Ackley Improved, maybe?

While certainly possible, 1thread probably will not be enough.  6-284 really sodomizes barrel throats.

Most sporter barrels can be set back a turn or two.  On a heavy profile barrel you can set it back farther.

any possibility of having it made into a different 30=06 family of cartridges, and then resize/reneck the 30-06 brass you have?  Have him build it as a 25-06, 35 whelen, etc.  Those won't overlap on your 308 nearly as much.

Or, if you are willing to wildcat, what about a 243/06  or 6.5-06
http://www.udarrell.com/243-06-ballistics-sierra.htm

http://www.accuratepowder.com/data/PerCaliber2Guide/Rifle/Standarddata(Rifle)/264Cal(6.5mm)/6.5%2006%20Page%20232.pdf

there is the 338-06 Asquare, but it is rare enough it might as well be a wildcat.  That to me sounds like a real great cartridge, and would really shine in the moments where a regular 30-06 would be a better choice than a 308.  (as in, 'leave that 308 behind, we are going after moose/grizzly, and the 308 just can't handle heavy 30 caliber bullets, so take your 30-06 and cook up some 200 or 220 grain hot handloads...well a 338-06 using a 250 grian or 275 grain bullet would be even better!)

there are a ton of really really good 338 bullets out there, not so much variety with the 358 for the 35 whelen.

It seems to me the 338-06 mixes the best attributes of the 30-06 heavy weights and the 338 winmag.

6mm-284 is no longer a consideration
« Reply #17 on: August 17, 2009, 10:32:25 AM »
We got together at the range yesterday.  We set up the target at 100 yards.  He shot a couple to readjust the scope and check the dimensions of the fired brass, then had me shoot.

Using a 200 yd high power rifle target (2" X ring, 4.5" 10 ring) my first three scored two Xs and a 10 that just barely missed the X.  4x scope.  1.94" center to center.  Factory Remington 180 gr rounds.

Now, for some of you, that sucks.  But I was shooting right handed (I normally shoot left), and the scope was set up for him, not for me (he normally cants the rifle, so the POA/POI relation changes if the cant isn't identical each time).  I also haven't shot a centerfire rifle (other than a couple of shots through someone's Mosin last year for giggles) in years.

I'm going to put a 3x9 on it and get it sighted in with some hand loads.  Then work on tightening the hand loads up to try for a one-hole load.

This is going to be fun, and I am so liking this gun already !!!
