ORIGINAL: Folically Challenged
Given your setup, it sounds like you're doing really well. There's lots of variables there: the flexing truck hood, your knees/hips/ankles moving, your abdominal muscles moving...
I spent $40 on a plastic Predator rest, & that got me going. But going toward what, however? Well, I was able to find the ammo that my rifle likes best. In a controlled cirucumstance, after many groups, I found my gun prefers 165 grain Hornady Interbonds.
So now I've "graduated" to shooting offhand, from my knee, and with a vertical handhold on a post. If, offhand,I can get 3" at 100 yards, & 6" at 200 yards, I'm happy.
But that's just me. I'm a hunter (when I can find the time), not a benchrest shooter. I shoot a Remington, not an Anschutz. I shoot factory ammo, not reloads. I want to mount heads on the wall, not framed targets with ragged holes.
So if you want to shoot tons of tiny groups, get the lead sled. If you want to hunt, go spend the $20 on sandbags, & don't look back!

Thanks all for the input. I just wanted to get a general idea of where I was at.
I thought of buying the lead sled, but that did not see any practicality other than getting sighted in more precisely. However, with shooting a few more shots and watching groups it is easy to tell when you are on.
I read all these people getting half inch groups, even read bragging about how he shoots a 1/4" group. Not sure how you can shoot a 1/4" group out of the 30/06 he was using when the bullet diameter is larger than that!
I bought the reloader mainly to cut down on cost, which means I can shoot more. I think if I can get to where I average an inch on these I should be fine. I have all year until season to practice.
Thinking the 7 Mag on antelope... 300 Win Mag on elk.... For Deer I am unsure as either should more than work.
Shooting offhand? You know this would be the last shot I would take unless something sprang and ran. I think you could always find some sort of rest, although probably wont always have the luxury of a full size 4x4!
