I have a pair of Sako Optilock rings and bases ready for installation in 30mm Medium. Had a Vortex 4-16x50 on them with no clearing issues. Let me know if you are interested. Most stores are out of stock.
My 7mm-08 Tikka T3 shoots under 1" with 140gr Accubonds and Ballistic tips, but when I tried some Hornady SST the groups open up to 1.5 and 2". I tried Nosler, Federal Premium and Winchester with the Accubonds and ballistic tips with groups under 1".
