I've reloaded a test batch for 44 Magnum and 44 Special using these coated bullets with Unique.... a low dose of Unique for mild plinking/pleasure loads. I've only shot about 50 rounds so far, very comfortable and good accuracy. I do plan to chronograph several variations, hopefully this month.

However, I'm not exactly sure if these are a true copy of the Keith profile. Perhaps others can comment?
The original Keith 250 gr bullet had a square grease groove. Lyman altered (rounded) the grease groove, to make the bullets drop easier from the mold, as the square groove bullets, tended to stick a little more. I imagine the other manufactures followed suit for that reason. This doesn't mean the rounded grease groove bullets don't shoot fine.
