Funny you mention .41 Special.
I have 2K pieces of Special brass coming and will be doing up some loads for that in the near future.
I plan on running a 215 SWC for the Special and a (when I can get the Mag brass) 240 Keith SWC for the Mag.
My friend has been loading .41 Mag for decades and I consider him an SME on all things related to loading .41s and .38 Super. I actually call him "Mr. 38 Super". So I will use some of his data to start with.
The other gun he sent out is an old Colt Combat Commander .38 Super that was his carry gun for years. 1950s era as I recall. Nice old piece. He really wants me to load both .41 and .38 S for commercial sales and I told him (and others) that I can't/won't load something that I have not thoroughly vetted, so I have to have guns chambered for those cartridges. That is how I ended up being sent the toys.
Another gent that has picked up a good bit of ammo, after doing so offered to send me one of his .41s if I would load for it, and others have asked as well, so I figured I had better start doing so. "If you build it, they will come!"
Those old Camo Pachs feel great, and I like the look for an 80s era gun.
