Hey I was wondering what some of you guys use for a vise when shooting and load development to take the human error out of it. I'm shooting a 7mm rem mag and it doesn't kick that hard honestly. I feel like when shooting at paper I get around 15 good shots before i start feeling flinchy. I dry fire a lot during practice to try to minimize it but after so many shots I just don't shoot as well. Do any of you guys use the lead sleds or something like that and how do you like them. I honestly would just like to take all human error out of load development and things would be so much easier. I usually always just shoot of sand bags. Thanks!
