[QUOTE="TRey16, post: 1175148, member: 94460"] @revturbo9967 I talked with Vortex's R&D guy today on the screws. He said that within the last ~6 months they upgraded the set screws from 4mm to 12mm and that solved the issue (mine has the longer screws). He also said to torque them to 8-12 in lbs. We also talked about the zeroing issue I was having and it was the "zerostop" being set in the middle of the range. I've got it cranked down to the bottom (he confirmed that I should be getting 28.5mil (285 clicks) on the external turret) and am heading out to shoot it again tonight and have my fingers crossed that I'll be able to zero at 100 yds for ladder testing. What loads have you been running through your LM? My current lot of components to test are: Brass - Lapua Bullets - 300gr Berger Elite Hunters and 300gr SMKs Powder - lots of H1000 and 1 lb each of IMR 7828, VV N165, N560 and N570 Primers - CCI 250s (can't find 250Ms to save my life) [/QUOTE]
