I shoot with a rifle club that got some shot marker for the target frames and no one has to pull targets and work in the pits. They work great and save time and make it safer to shoot longer distances. We most often shoot 600 yds. and then go to other ranges and shoot up to 1000 yds. The shot markers allow you to shoot more and get more information off each shot. Well I ordered up a set and will use it for load developement and work with different bullets to find the best results at closer ranges. It is made in Canada and will take two months min. to get it done so they can ship it to me. Check it out on the web sight and this may be helpful for others as well.
