I have read some real good reports of the 460 Weatherby, and there are several wildcats held in good esteem here based on that case. How does the rebated rim of this brass figure in? Everyone says the RUM brass is bad as it has a rebated rim, but the Wby brass is even more rebated.

The reason for the question is that I've been looking at getting a real big bore built for a while now. As nice as it would be to get a double, reality says it'll be a magazine rifle. So, I'm considering the 495 or 500 A-Square. Being based off the 460 Wby case, will this rebated rim cause feeding problems?

I haven't decided on an action or anything yet. I'd like to pick the cartridge and then get the right action for it. I do like the fact that the 495 A2 will fit in a 375 H&H length action. That's a real plus in my book. Any other comments on these two choices would be interesting as well. Are there any other 50 caliber bolt rifle options that might compete? I'm not real keen on the 500 Jeffe for some reason. Thanks.

"all" belted rounds are rebatted, to a greater or lesser extent.

in my experience, especially with 550 express, there's no feeding issues associated with the 460 weatherby that's not the same with the 7rem.

only a few are saying the rum case is bad, due to rebatted rim... that's a PII as far as I am concerned... the rum has feeding troubles due to geometry, (taper)... but that's very much like the 416 rigby in that matter

my experience, go with the 500a2 or 510 wells, in a cz 416 based action, and it's a pretty easy rebarrel and ramp work... you might replace the extractor with one from a 375, btw.

I was hoping to hear from you on this Jeffeosso. If I recall right, you have/had a 500 A2 that was throated for 50 BMG bullets. A couple questions, if you don't mind:
- what action is it on?
- I assume that rounds so loaded are single-shot only?
- did you modify the front ring to allow long loaded cartridges to be ejected?
- how does the longer throat affect accuracy when using normal hunting bullets?

caption,
RAB has the long hroated a2, I have a long throated 500jeffe.. and, frnakly, wouldn't build another one (done 3)...

the long long bullets you can't feed from the mag, you have to "mash over" the extractor on a cz or enfield.

the enfield is only "cheap" if you can do all your own work.. otherwise a $150 enfield requies a couple hundred in smithin'... so the CZ is a good value.

my jeffe is very accurate, from 530gr casts to m2 ball.

it' throat is nearly an inch long

I knew it was one of you guys that had one. Thanks for the info. I was thinking a CZ 550 action would be the right choice for either of these. I imagine that getting the Rigby-sized one would mean very minor (if any) feed adjustments. I also imagine that a barrel recoil lug is mandatory.

Would it be a cardinal sin for me to want this in a heavy-duty fiberglass stock instead of fancy ($) wood? I hate trying to use rifles I'm scared to take out of the safe. Are there any decent synthetic stocks for the CZ available yet? Any recommendations on a barrel length, supplier and twist?

Get a 500a2 with a Mcmillan express stock and it needs to be glass bedded by someone with real DGR experience. You also need a barrel mounted recoil lug. Please stay away from a rebatted rim anything or a 495 a-squared. Heed my warning and advice or prepare to suffer( money and ridicule),-Rob

But Rob, the 500 A2 is a rebated rim - the rim is much smaller than the belt diameter...

Glad to hear that the McMillan stock is a good one. I like their stuff.

Now, who is recommended for building a 500 A2 rifle? Anyone done a few of these already?

Sorry, but I do not consider a belted magnum case to be a rebatted rim. I have never heard them described as such. While technically I suppose you are correct, A true rebatted rim cartidge is Non-belted with the case head being much smaller than the case body. A .060 thick belt does not count. True rebatted rim cartridges are to be avoided IMHO and are Notorious for being extremely difficult to get to feed properly i.e. the 500 Jeffery or .490 based .585 Nyati. They tend to porpose in the magazine ramps upon closing the bolt resulting in bolt overrides. No one I know of ( who has a clue about how Mausers feed) has difficulty getting belted magnums to feed. The 500 A2 is probably one of the easiest cartridges to get to work on a CZ550 magnum action. Talk to Pac-Nor, I think they could put one together for you.-Rob
