300 Rum Range Results. Load Development Help Please hey guys, just wanted to show some of what i've been doing. try to get a little more active on the forum so i loaded up some of the hornady 208 grain amax bullets with a starting load of 85 grains of H1000,(just using up what was left) in a remington case with winchester large rifle magnum primers. i wanted to mess with seating depths, so i headed to the range to give it a try. i shot some rounds loaded .020", .050", .080", .110" off the lands (measure with a hornady bullet comparator set up in my dial caliper) i used a cheap old rest at the range and shot each load not really noticing much difference between the first 3 loads, all between 1.25" and 1.5" groups, but the .020" gave about an 11/16 group. seems promising. but this was all with a very wobbly useless rest so i'm not going to look too much into it until i get some solid resultsfrom the next load so i went back home and cracked in to the bottle of hodgdon retumbo, and loaded up some rounds with the same specs but 85 grains of retumbo. i headed back to the range and shot the load that was .110" off the lands. my first round with no rest. this is the flyer, then shot the other 4 rounds with a bean bag my uncle handed to me. this definitely helped out. and this was the result. when that was done i adjusted the scope of a MOA and right and MOA shot the load that was .080" off the lands, all of course with my new found friend the bean bag. this was the result now the load that was seated .050" off the lands was shot rushed at 200 yards in low light conditions, being hasty i really just wasted that load. so no results on that on. i ran out of time and still have yet to shoot the load that is seated .020" off the lands. but i'm curious to see what the results will be. i would like to be able to use a round that fits in my magazine. but if the .020" seating depth shows enough improvement i might have to forget about that. now i guess the next step is to load up some more rounds increasing the powder charge. the seating depth to be determined, i need to shoot that last load before i go any further. this LRS stuff is pretty damn addictive. what kind of improvement have you guys found with changing the seating depth of a bullet?
