I'm just curious to know if there is any interest out there in the 495 A-Square. I know that for a while there was a flurry of interest in the 470 Capstick.

Do any of y'all use the 495 or know anyone who has? It seems that the 500 A^2 has a modest following. I wonder why one never sees much written about the 495? Perhaps my memory is faulty but was/is there a problem with the neck tension on the bullet? Or am I thinking of another cartride...wait, it seems that that was an early criticism of the 458 Lott. Anyway, forgive my rambling. What say ye about the 495 A-Square?

Thanks,

I have no experience with it, only the Wells, an earlier version of the 500A2, derivatives of the 460WBY, all based on the 416Rigby, all requiring a long action. The 495A2 makes alot of sense to me if working with a standard length Mauser.

the .495 is .100 shorter than the 500 a2. and if loaded to the same pressure, it would be less than a 500 jeffe (either the .495 or 500 a2)...

all in all, a good and useful round

depends, if a 600gr bullet at 2250fps is enough for you. I am finishing up a 510 Kayser Express, so named to differentiate it from a host of other large .50's. Take the 416 Rigby unformed (cylindrical FL case 3.000") and neck it to .50 caliber. I used the 510 Wells as a model, just had the reamer maker "lose" the belt. The Wells case it trimmed to 2.88", I expect as a result of necking up 460 Wby cases. Ask me again in two weeks for good chronographed, accuracy tested data. For now, ask FLA3006 about his results with his 510 Wells.

I bought one from a fellow member of this site back in august of 98, just after I signed on. I can't remember the members name but he had 2 or 3 of them. It was an A-square hannibal rifle, and it was ugly as hell! I shot it alot but later decided to build myself a .500 Jeffrey. I sold the "club" at the Tulsa gun show. In the end I built a 458 Lott and took it to Africa. Not much I can tell you about the .495 except there are better options out ther, then again thats usually the case. At the time brass was hard to come by, it may be more available today but I don't know.

It was the first round made with the ghost-shoulder, meaning it tapers from the belt to the neck, wich is parallell, unlike the 458 Lott and Winchester, wich tapers from belt to end of case. The Capstick is the other cartridge made with a ghost-shoulder, both designed by A-square. They requires 2-die-sets, whilst the Lott and its likes require 3-die-sets. Seems to me to be a good solution! I guess the only reason for lacking popularity is its big brother .500 A2. Most actions that take the .495 will also take the .500, and Bigger Is Better...!!

CZ550 in .416 Rigby + .510 barrel + .500a2 chamber reamer = eaisiest big bore conversion possible. A moron with a dremel tool can make it feed. Save yourself lots of grief and follow the equation above. No one who has done it has ever complained. Throat for .50BMG Milsurp bullets and have a ball with XMP5744. -Rob

As I recall the thought behind the 495 A-Sq was a 50 that would feed from a Win mdl 70, and A-sq found out that was better in theory than reality.

Also those of us that have the 50's know that there is no good reason to build a 50 on a std sized action, a 50 should weigh at least 10#'s all up, so you might as well use a large action, and since we're after more power than the 45's, you want to use the full size 460W case.

Well, if you wanted to make a 495 A2 what would be the best action to use?

CZ 550, but I'd go for the 500 A-sq. You can always download the larger case, and it's best to go with a more popular chambering should you need to sell it in the future.

I hear ya about the 500 A2 but right now I am interested in either the 495 A2 or the 470 Capstick. I'm not going to run out and have either one of them made this week but it's a project I have in mind for the not so distant future. There's just something about the straight walled cartridges that interest me at the present time. Next year it will be something else, I'm sure.

If you are down to those two choices, then I think I would be "Capsticking" it.

There is always the 550 magnum
