Anyone else powder coating their air gun slugs?

On my journey being new to air.guns I bought a Airforce texan 50 cal .and have been casting and shooting it for a close to a year. Shooting my gun tethered I couldn't get to to shoot better than 3 in groups at 100 yards with a.few different cast slugs. After watching Elvis ammo on youtube on powder coating and the benefits of I decided to give it a try. Any ways if my barrel it was.a night and day difference. My groups .tightened up and it became consistency accurate. I was using lee liquid alox before. Having sticky bullets that gather dirt and dust are not ideal for.when hunting. I didn't like.the idea of. handling the lead all. time .either. I just wanted to see if anyone else had positive experiences powder coating their slugs?
