So far I haven't had an issue with copper fouling, but I do clean the gun well after every trip.
We've loaded some FMJ 165 gr boat-tailed spitzers for the next test rounds, but I would not be able to load the tube mag with them. too dangerous.
I'm intending to shoot 2-round groups & we'll see if the fliers calm down.
Copper is hard to get out. I am not sure how effective Hoppe's is on copper but my MVP had a streak in it and it took Sweet's and J&B to get it out.
