Gents, Paul T has been after me to get this thread going for awhile now. I was holding off as this was quite a departure from normal for me, going into both "wildcat" and custom stock country. I wanted to have the gun in hand and do some load development and give this rifle at least some reasonable trigger time before writing up a report. As some of you may recall, Paul T started a thread a couple of years ago on his 500 MDM. That caliber is a wildcat caliber that is amongst a number of calibers developed by the guys at B&M Rifles and Cartridges. Here's the link to Paul's thread: http://www.africahunting.com/375-up/4832-ultimate-stopper.html And a link to B&M : B & M Rifles and Cartridges - Home Paul's thread was the start of my interest in these rifles, but I wasn't so sure about them. A short barreled DG rifle, that thing is going to kick hard and leave marks! I was also not so sure about going with the wildcat caliber, would brass be available with the proper headstamp? A number of other questions in my mind. At that time I already owned my M70 in .375H&H which I really came to love and still do. Then sometime about a year ago or so I picked a beautiful CZ 550 in .416 Rigby. That was my first CZ and I really like most things about the rifle, but came to not like the caliber so much. It was so easy developing loads for it, but that bugger kicked hard. I could shoot it accurately so I don't think I was flinching, but within 10 rounds or less on the bench I was done. I guess that's okay, but when I like to shoot. It's 40 plus miles round trip to the range for me, so when I go I don't like to just send a few rounds and then go home. So I had been keeping up with the B&M's and decided in the fall of last year to give Michael at B&M a call and chat with him about his rifles. And then in January I got to meet him at DSC and handle a few of his personal rifles. He had one that he was selling for a friend of his that had a few of the B&M's and I guess one more than he needed which he decided to sell. That rifle ended up in my possession, but that was just the start of the project. The next part of the story will be in my next post. But here are some pics to start on.
