ol' spark,
The 338 project if being mostly done by me with a local smith doing the metal work. Doing nothing more than swapping the Win bbl for the RUM bbl and bringing the brake over. I got the RUM bbl, new unfired from Kirby for 45 bucks.
Will use it to see now much more of a cartridge the RUM is over the WinMag. The Win bbl was shooting 250 game kings and 252 Wildcats into 0.5" @ 200yds @ 2930 FPS. Cases were only a "little" sticky.
I will also use the RUM to further test the frontal ignition system in preparation for the 270 AM. The FI idea (stolen from OKH) has some good features and isn't that much work. It did give me a real feel for how much expansion the head of a case experiences when the thing goes bang. I must have been, according to the "local" smith "who knew PO Ackley" up around the high 70K low 80k pounds of pressure. Whoooo Hoooo!! It did launch little brass tubes downrange.......Once in a while......
The whole idea is to lengthen throat life but there are other benefits also.
After I get done with the RUM experiment it'll be come either a 338 Edge or Tommy. I'm figuring a Tommy as the Edge is nothing more than the 300 RUM necked up or the 375 RUM necked down. Nothing "sexy" about that.
You're bitchin' about wind!!!! Woke up to 4" of heavy wet snow this morning. How about them apples
By the way, some tests were done on the secnars and they behaved like solids. Accurate as heck but ended up bananas and penetrated some pretty serious steel that nothing else had ever touched.
