...work up some good dope for your rifle and pellet choice and then practice to make sure it works.Most new shooters come to a match with dope at about 3 known distances and then wonder why they shot 20% in their first match, especially when they were shooting half inch groups at the 3 distances they practiced. Given you have a reasonably accurate rifle good target ranging is about 50% of the success in HFT, followed by good dope at 25% and the shooter at 25%.The dope sheet for one of my rifles has holdover data in 1 yard increments to 20 yards, 2 yd increments between 20 and 44 and 3 yds between 44 and 55. Having got comfortable with the Chairgun software I always use that as a starting point when working up my dope. When using Chairgun it is critical to make sure you have very accurate measurements for velocity and scope height for your rifle. One of the best ways to test Chairgun is attached a target with multiple bulls to a cardboard box and then attached the box to a long tape measure. Put the target box out at 55 yds or the farthest distance the tape will allow if less than 55 yds. Set up on a solid bench with a solid rest for your rifle and shoot 2 or 3 shots using the Chairgun dope at each of the distances you want to verify your holdover for. Record the actual holdover of your shots if different from Chairgun. I usually find it easier to shoot at a bullseye on each target and use the mil-dots on the scope to measure the drop from my point of aim. I find it easier to calculate an average holdover for each distance. I then compare my drop to chairgun and note any differences. It is during this process you should work up the distance chart for your scope and side-wheel, for as you will find the stock markings on the factory side-wheels are usually not accurate enough for competition. Once you have calculated and confirmed your holdovers from a bench you need to practice on targets of unknown distances from your bucket and sticks. Range the target with your scope use your chart to get your holdover and take a couple of shots. Then check the distance to the target with a range finder or a tape measure. If your shots consistently missed the target you need to determine if the ranging was off or your dope was off. Keep working on this process until you can range and hit more targets than you miss on the first shot. if you can do this you will have a lot of fun shooting field target.Preparation and practice are a lot more important than the equipment in FT. However I will say a decent mil-dot scope or some scope with clear crosshair distance markings with separations no larger than a mil-dot is highly desirable if you are going to compete at the upper end of the competitive scale. Also do not confuse price with the quality of the optics. Jim in Sacramento
