[QUOTE="woods, post: 564826, member: 6042"] I've got one in my future just haven't pulled the trigger yet. I have a Beretta Mato 300 win mag which shoots the 200 gr Accubond at about 2900 fps and I would like to bump that up to 3000 fps. Plus just the fun of doing a wildcat. I have a 375 Ruger and brass. Here is what I have discovered: 4D has a reamer for rent [url=http://4-dproducts.com/display.php?group=Rifle+Calibers]4-D Products Rentals[/url] [IMG]http://img.photobucket.com/albums/v663/bwestfall/RELOADING/30_375_Ruger.jpg[/IMG] The reamer should clean up a 300 win mag chamber and the barrel may have to be set back a thread or two. The hard part was figuring out how to get the brass neck sized down. I called Hornady IIRC (might have been Redding) and there was one of their techs that shoots one and they recommended stepping down the brass with the following dies in sequence: 375 Ruger FL without expander 338 RCM FL die (neck sizer wouldn't work because of forcing cone internal slope) 300 RCM Neck Sizer I got the dies and they do work, here are some pics with 375 Ruger and 300 win mag cases [IMG]http://img.photobucket.com/albums/v663/bwestfall/RELOADING/DSCN1855.jpg[/IMG] [IMG]http://img.photobucket.com/albums/v663/bwestfall/RELOADING/DSCN1856.jpg[/IMG] [IMG]http://img.photobucket.com/albums/v663/bwestfall/RELOADING/DSCN1859.jpg[/IMG] The 30/375R neck resized case grew about .010" in length but no significant increase in neck thickness. Of course, AFTER you have fire formed a case or two you can send them off to get whomever to produce dies; Lee Collet, Redding Body Die, et al IMO it would be a gun you could shoot without a muzzle brake. It would essentially be a 300 win mag MAGNUM without a belt where you could have low headspace and not worry about case head separations. In my case where I have a 300 win mag and a Lothar Walther barrel existing on it, the price would be around $300 without the cost of a barrel or refinishing the gun (hopefully). Just haven't got a [IMG]http://img.photobucket.com/albums/v663/bwestfall/roundtuit.png[/IMG] [/QUOTE]
