Not loading but loading related. Since I had to break out the Moly Coating equipment to coat some 721 Lazzeroni Firebird bullets, figured I’d work on coating bullets for my 17 hornet CZ. I got a great deal on factory ammo but I’m down to my last 100-150. My dad is back scouting prairie dog towns in the panhandle of Oklahoma. So better start developing a load and switch over to moly. Got 300 coated earlier this week. Here are 500 20 grain Varmagedons coated today that still need to be waxed if I feel like it. Got 400 20 gr. Bergers up next.

I thought moly coating ruins barrels?

Not been my experience...but that's what they say on the internet so it must be true. But using a bore scope to check the lands area and no Moly build up in those guns I use it in...then again I clean my rifle appropriately for moly. So, no issues and get about 2x as many rounds before cleaning with cleaning taking about half as long due to reduced cooper fouling.

I only use it in my accuracy varmint guns. With Moly I get 30-40 rounds off between cleanings. Plus my 220 swift seems to get about an extra 500 rounds out of the barrel before accuracy declines which is in the 3,000-3,500 round range. My barrels get retired when they open up to .75 MOA or there abouts. I haven't shot out enough barrels in my 243 AI to say.

I trust what you say. So would moly coating be worth it on say ar15,ar10?

I think that is where people supposedly have had trouble. They shoot hundreds of rounds without cleaning. I would only consider it in an AR if it had a match grade barrel and ok with cleaning every 50 rounds or less. Otherwise not worth the trouble. The key with moly is to not let copper fouling get started.

Loaded up some 223 rem for my ar. Did 10 in Winchester virgin brass and 10 in starline 556 brass to see what kind of velocity i could get from each as i started to see pressure. I did this to decide which headstamp i wanted to use in this load. From what i could tell there was not a tremendous difference in the velocity of either at a given charge of powder. Used federal ar match primers, 77 smk, and imr8208 xbr.
