Hiya. just pickin brains here, but does anyone know anything about or have any experiance of the 30 284 cartridge (.284 win case, necked out .30)?

 

cheers

Yes, it's called the 7.5X55mm Swiss GP11 cartridge.

 

Seriously though, if you neck up the 6.5-284 or 'straight 284' to 30-calibre, you get a result that's a 7.5 Swiss clone in capacity and performance even if they're not interchangeable in either's rifle chambers. (Same as the European 7X64mm and US 280 Remington.)

 

This is no doubt one reason why 30-284s are rather thin on the ground. With a lot of Swiss and other European expertise and experience in optimising the 7.5 for match use and excellent RWS brass available for it, there's not a lot of incentive to choose a wildcat over the existing factory round, especially as it will at best equal the yet more common .30-06.

 

The other reason (assuming we're talking match use or what some American deerstalkers call the '284LT' (Long-Throat) and non-SAAMI COALs, the 30 doesn't do anything that the straight 284 or its slightly improved Shehane version won't do better in terms of external ballistics (or most sporting use too for that matter).

As Laurie-and the 30-284 never did much in US either...there were established cartridges for hunting,and even the parent 284w was nota success in it's hoped for hunting niche.

I've seen one in Shooter's Forum. Post by Assassin 12-07-2016,no ballistic/load detail-the Redding Custom dies were*84523-and the thread didn't get many replies...one mention of 155Amax@ 3000fps.

The 284 rebated case was intended to fill an alleged demand for a woods deer rifle,not bolt action,to upgrade the older 30/30 class carbines. In 1963,Winchester brought out the models 88l/a and 100 s/a in 243,308 and 284,the 88 being a fine modern l/a,a bit better maybe than the Savage 99 and in those modern cartridges. But the 130 g loading wasn't liked-too much meat damage-quite likely-the 130g Classic 270 load being copied wasn't a 100y woods cartridge.The S 99 and Browning BLR were also briefly offered in 284.BUt sales were poor-and it was discontinued and isn't now offered. There were also Rem pump and Browning semis....and the 284 lacked just a little performance compared to the very well established 270w and 280w,let alone the 30-06 and it's wildcats.Shame-it's a good medium game cartridge,just as are the 270/270 etc class,and the 88 was innovative-nearly a bolt action,that worked with a lever,and was way cheaper than the excellent Sako l/a.

The 284's potential-good case capacity,shortish fat case,shortish action -was recognised later by Bench Rest shooters and the 6.5

X284 enjoyed top status (the 6-284 is pretty good too),and this reintroduced quite recently the "straight" 284w and it's upgraded Shehane wildcat,both now very popular LR target rounds,and the 284asa medium (inc Red) deer cartridge-doing pretty much what the 280rem has always done,but offering a shorter action....though just where a 30/284 would outshoot a 308 can't be very wide.

 

And there we have it....of course there are somewhat more potent cartridges-the recent 300Ruger CompactMagnum,or 300WSM in the broad 300Win Mag class.... And the 25-284 nearly made it as the 25-06 Rem,and would have offered a few advantages,but tthe 25-06 had an illustrious parent,and was well established as a wildcat....

As with Laurie's target history,,the 30-284 just did not have enough distinction to make it,among other fine rounds.

I like the 88 (and classic 99)...in 284 they would be collectors items.....the 284w /Shehane is a very fine 1000y cartridge,in bolt action of course.

Thanks for all that fellas.

As per some of my other posts on this forum, it was just a query as I'd not really heard of the 30-284 before.

I recently had a .308 target rifle rebarreled with a straight .284 win bartlein barrel which shoots like a dream, and its the same boltface.....luverly! (thanks Mik for the barrel work & Laurie for the reloading advice).

I simply wondered what else could be done with the .284 case? I'm fully up to speed with it necked down 6.5-284, then read about it being necked up to a .30, and ended up thinking would it be any use as a cartridge for heavy .30 cal bullets, what with its extra 10 grain capacity + bullets seated out longer in a custom chamber.

But then, in comparison to the 7.5 x 55 swiss I guess its too close to call.

Hey, if you don't ask questions you never learn anything eh?

Sounds like a 308 without any convenience!!

[ezmobile]

Yeah, but with a larger case capacity, and dies are available (Redding).

[gbal]

ezemobile,true- dies are availablebut also for lots of cartridges,and the 284 (66H20) advantage over 308(54 H20) is clear,but the 30-06 edges it (68H20) as does the 280,let alone the 7WSM (83 H20),and plenty others. 284w probably necks down to a short semi mag 6.5/6mm rather more happily that necking up to 30 cal.....

 

 

....One factor to look at is COAL in a magazine rifle...the 284 is only just a short action,and will be compromised in capacity with long BC bullets that need short mag fit ,and way off the pace with the long action cartridges allowing considerably longer COAL,and therefore longer,heavier better BC bullets ,as well as more useable powder capacity.

It gets complicated,nor does bullet choice remain static-but generally the better ones get longer/heavier,and this is also so for 30cal competing with the excellent 7mms.Target single shot rifles would be less vulnerable though.

One excellent niche for the 284w woud be in Mauser 98 sporterised...it's just right for that action,and gives 280rem performance-of course so does a Rem 700 off the shelf.....

 

Interesting and often informative to consider these things (we do get very wet/windy Sundays where shooting is less tempting)....

....even with the excellent 284/Shehane...... :-)
