Yes I have,
I used Berger 110's which shoot very good in my rig with the Nod going to Randy R, Bibs 118-7, bullet that will shoot low 1's.
Always looking for something better, just noticed that the pressure ring on cheeks is a little less .3084 to Bib's .3087 and a shorter bearing surface on the cheeks.
Very hard to beat the Bib's and will continue to use them in competition just always looking...
Also Tried the knight 118-10, not for my rig, throated wrong for them, only had .010 in case at land touch...they were scattered all over the paper no matter what I did.
