Best price I found so far are the Lightfield brand. I picked up a box each of the 2.75" ($18/5) and 3" ($20) from The Shootist in St Albert. The 2.75" were same hole at 50yds and dead on at 100. I compensated at 100 thinking they're dropped like a freight train like my home rolled Lee's but nope. They hit where the crosshairs rested.
Slight west wind breeze but still good imo at 100yds for s shuttle cock slug
