I successfully loaded some 175 SWC tumble lube bullets my buddy Stoney just cast to pay me back for some assorted 7mm bullets I gave him.
I had an old unopened can of Blue Dot floating around and from all my reloading books, 10 grains seemed like a perky starting load for my Colt Double Eagle. My brass was a bag of 100 new Winchester, primed with CCI large pistol primers.
I taper crimped the mouth to .4205-.4210 and all seemed great. I got most of the lube off of the exposed bullet w/ a shop rag and proceeded to the gravel pit for lift-off.
Much to my happiness the loaded ammo performed perfectly. I shot a 4-5 inch group at 25 yds. I think I can do better, as I was focusing on gun function more than perfect shooting. This gun shoots factory American Eagle 180's very well. I will chronograph this load soon to see where we are for velocity. I'm not trying to hit the moon, just around 1100fps would be enough for me.
I hopefully someday can get a Smith 10mm of some flavor as the 10mm is becoming a favorite. Later.
