......which is basically a .300 AI. So far, I can't find any specs on the AMU. I read on the net where one guy punched his out to .308 Norma Mag. Given the rarity of that round, I'm not fond of that conversion. Does anyone think you could shorten barrel a bit and make it a .300 Weatherby?
Any suggestions gratefully considered.

Maybe you mean 300 Norma, not the same as the 308 Norma.

The 300 Norma is based on a shortened 338 Lapua magnum.

Maybe I mean what I wrote. Geesh.

Both the AMU and the .308 NM use the .300 HH as an initial case, so the mentioned conversion makes sense.

I had heard of an AMU on a 404 Jefferies case. I guess this isn't it.

Gotcha!

pictures on amm-one. blown out&shoulder moved foreward 300 weatherby mag. similar to 300 jarrett but less body taper it appears. like full length 300 A.I.personally i would fire form 300 weatherby in it if dies can be gotten & you hand load. 300 weatherby seems to be one of the easier full length h&h cases to purchase these days. i dont know what the rifle is but its a good cartridge. i have seen many,many 300 jarretts that were .5 & better moa rifles.

as little taper as it appears it would take a few threads to get to 300 weatherby diameter but without the dimensions we cant know. is it a thousand yard heavy rifle or a sporter?

Phil:

It's a sporter made by J.K. Cloward on a FN action for "Ken Henshaw" (I suppose he is deceased but if anyone recognizes the name I'd like to hear more about him). It also comes with the original .338 WM barrel. I've always wanted a Cloward rifle so finally scratched that itch on what I consider to be an excellent buy on GB ($1050, mostly, I suppose, because of the caliber and relatively plain wood/stock work).

I've read, which certainly doesn't make it so, that the .300 AMU is very similar or identical to a .300 Ack. Imp. I really don't want to reload for this round, but anything is possible. I'd prefer to make it into a .300 Wea. or .300 WM. Maybe rebarrel?

Gatogordo,

Without any intention of being contentious, I have to ask because I'd like your opinion...

If you re-cut the chamber or re-barrel the rifle, is the rifle still a Cloward?

I see it as being a situation where if you change anything major physically it is no longer a Cloward but something other than that.

In that case, why not just buy a .300 Weatherby or a .308 Norma Magnum?

Regards.

Cloward is closing down operations. There will be no more, I'd keep it as is

Because an ordinary chambering/barrel (not including special barrel work such as octagonal, etc) is not integral to the essence of a rifle, as I see it. In the end, it is my rifle and I am not concerned whether it is a "real" Cloward in someone else's opinion. I might wind up rebarreling it, and I can save the AMU barrel if some purists wants a "real" Cloward. I'm still gathering information.

I own at least 4 .300 Weatherbys, (luckily no .308 NMs) and want to shoot this particular rifle. I will shoot it, hopefully not in .300 AMU.

I like Cowards stock designs. When I was stationed in Whidbey Island a thousand moons ago, he was well known in the area. He had some nice synthetic stocks made by someone else. Fit great. Maybe not someone's ideal of a classic, but they felt amazing.

I am with you FatCat, do whatever you want. It's your hard earned dollar!

very nice rifle. thanks for picture link.

Gatogordo,,
I just read that Winchester had made some special long range Model 70's that were chambered in .300 AMU. So, they would have some exact specs somewhere. A fresh new barrel chambered in the same case size might be the easiest solution.

keep the original barrels and have a good smith put on a properly contoured barrel in your desired chambering and enjoy it.
