470 A2? Login/Join

The recent threads on doing a 470 on a RUM case point out repeatedly that it is rather difficult to come up with something that a wildcatter somewhere, sometime hasn't already done....

So has some one already done this one? If so, then what was it called?

BTW, I acknowledge it may be pretty close to the 470 Mbogo....

Strikes me that it would be one mean mistreater
OR
Could be downloaded for a somewhat slower, still plenty mean, lower pressure round.

Different paramaters from the RUM project; however, I would think it would be real doable in a CZ550 (inexpensive) and put the savings towards the Weatherby brass supply.

Surely Jeff or RIP have nudged up against this one.

Comments?
======================

Sidenote: I've got a 458 Lott (and like it a lot) and would probably just jump up to the 500 A2 and be done with it. That 470 AR thread just kinda got me to thinking about it a bit.

Hi ElkampMaster,
I would go out and try a 500 A-Square and see if a 600 grain bullet at 2400 fps is really something you would use. Lots of guys think that they would like to do it but on an un-muzzle braked rifle that is of a usable hunting weight it will wear on you. I have one and shoot it but I think it's about the top of the scale. If your thinking about a muzzle braked rifle then it a different story. Rob Garnick's 585 with a muzzle brake has about the same recoil feeling as my 500 A-Square.
Take good care,
Dave

470,

Before making that kind of "jump" I would definitely want to try it before I built it.

Assuming I followed thru with it, then I'd probably follow MRLexma's route with the 500A2 and load it down to a comfortable recoil (458 Lott hasn't "tapped me out" yet) and still have "the reserves" for when the ocassion calls for it (probably some wise ass at the range).

I figure that 600 grains at Lott speeds (and low pressure) would probably be plenty. Nice to have the extra giddy up and go so as to be able to trim the barrel down just a smidge (removable muzzlebreak perhaps) and bump the bullet weight up a bit without "running out of throttle" as it would definitely be a iron-sights/stopper kind of rifle.

Ultimately though, banking coin for a Searcy double in 470NE or 500NE, though decidedly less powerful, with their quick, controlled one-two punch, they would likely serve better as a hunter's tool IMHO.

It is fun stuff to toy with (what to get next?) and though there is bigger out there I pretty much anticipate that the 500A2 would be the "king of any hill worth climbing" regarding power bolt rifles (perhaps even your 470 Mbogo holds that title for that matter).

The .470 AR looks to be a completely new approach because it is based on the Remington Ultra Magnum brass, which is already unique in its own way.
Being able to use existing rifles from different mfg's. beginning with a fairly reasonable initial purchase and minimal expense to convert it is also a new twist.
Combining the two, starting with the Remington brass, makes it an attractive proposition available to many shooters.

It may be 'similar' in ballistics to many previous or existing wildcat cartridges, but it is unique in its timing and approach...
If I understand its concept correctly.

Just an input :

Shooting a rifle with a muzzle-brake WILL damage your hearing even if you are wearing both plugs and muffs. Your hearing is one of the few things that can not be repaired.

Is it really worth it?
