Have had and still have rifles chambered for both '30 cal and 7mm. My choice is 7mm (7x64 Brenneke) all day long. I don't see or have experienced that the 30' cal did perform any better on game. Mostly using 7x64 and then 308 W. My 300 WM and 30 - 06 AI are unfortunately collecting dust only...
Buy yourself a fantastic Heym Precision SR 30 (Heym USA) in 300 WM and don't look back. Will cost you round about 3,5 K. Some money left for a decent scope as well.
No it doesn't require a magnum action, but since it's an odd (for the USA) medium case head due to dimension a gunsmith would have to open the bolt head slightly. Best would be to acquire an action for the caliber and then construct the wildcat of your choice. I would strongly recommend to...
You are absolutely right what you are saying, but you can at least find two major German manufacturers, RWS and /or Brenneke pluss Swedish Norma, which are loading accordingly to CIP - data and are outperforming SAAMI - loads all day long.
22' barrel and no extreme distances? In my eyes 7x57 Mauser would be a very good option. Originally with a 1 : 8,66 rate of twist it can shoot everything from 100 - 180gr without issues. Low recoil and fine accuracy are following additionally.
Please go to CIP - data, and there you will find everything you need included drawings! Brass comes from Horneber / Germany. Tel Nr and other information is available on Horneber's nett site. Robertson Brass in Texas will also produce brass if requested.
You can't override the physics ... simple as that. Living in Norway, European regulations due to CIP - data are both decisive for me and European manufacturers! That means max. pressure of 3800 bar or 55114 psi for the 6,5x55 SE. There is no free space for "extraordinary chamberings" or other...
In my opinion it fails when the OP is trying to compare both cartridges in terms of performance, because the 270 W is working at a (almost) magnum pressure level while the 6,5 x 55 SE on the other hand is very moderate regarding this. The 270 W simply plays in another class, and while it can...
Brass is made by Horneber in Germany, who is delivering on regular bases to the US, Graff & Sons etc. RCC (Texas) will surely be capable and willing of manufacturing them, also in small quantum. I had a conversation with the owner of the company couple of months ago, and he confirmed that it...
