Went out to see how the newly throated barrel in my 1911 would do. Load was a MP 200 SWC coated with Hi-Tek, 4.8 gr Promo, and mixed brass. I fired 200 of this load to see if leading was going to occur. This bullet and coating did give some leading in the first inch of the bore before the throating.
No leading was seen. A few wet patches did pick up a few rough spots but I think these are from a few bullets that may not have had the coating fully cured. No streaks of lead of other fouling could be seen with the naked eye after the bore was cleaned.
I did chronograph 50 rounds with the LabRadar. I was a bit surprised to see this load give 950 fps on average with 4 rounds going just over 1 K fps. The load does shoot well but I may try lowering it to 4.5 gr and see what it does.
No groups were fired. This was a day for fun. A few pop cans were killed and some lead was retrieved from the berm.
