First, what are some of the common things you call "bad follow through"?
Which bodypart? I'll go with the hands. Off hand, letting go of the joystick, relaxing the squeeze, dropping the shoulder..... Trigger hand, pulling thru, pulling sideways, finding my finger still on the trigger after the shot, with my HBR setups I get all sorts of bad habits because "done right" I tend to get a swollen knuckle..... I don't even know what's "bad" except that in one of my slumps I was getting odd fliers, I couldn't seem to get a handle on it. Someone a lot more experienced than me told me to check if I had enough overtravel slack...... I didn't. I fixed it. My problem disappeared. That time.
Second, if "it's incredibly easy to fire 1/4" groups with a good rifle, WHEN THE RANGE PERMITS IT" and you're "refer[ring] to 5-shot groups with an aggregate group being 25 shots, ALL holes counted," I guess I haven't been around any such range conditions. I'm interested in hearing your description of such conditions.
Can't do it..... I can't always recognize "good." Some days look exactly the same but shoot completely differently. Still days can be the worst, a good steady PNW rain is awesome, Christmas card snow can be good, if I had to bank on a condition on my range I'd say a right-to-left steady between 5 and ten mph is solid for testing.
Sometimes.
For me, I've got to shoot it.
Third, can you elaborate on "clocked barrels"? I'm not familiar with that term.
Clocked simply means I set the curve of the barrel where I want it.
Fourth, what are some of the common scope installation problems you see?
#1, Just bolting the stuff together.
#2, Buying the best stuff money can buy like billet rings and machined bases, and just bolting them all together.
#3, Buying a machined rail so it's "straight" and getting out the red loctite.... and just bolting it all together. With loctite no less, "so it stays together" LOL.
I will say at this juncture that Jerry Stiller makes a rail and pin system that I could ALMOST just bolt together and trust it...... but I still epoxy them down ...... And well centered. You point the barrel right when you install it and you don't need to boresight.
I dunno, it's next to impossible to list all the problems, I've just found and eliminated them over the years. I've owned a Hood Scope Checker for ten years....and have several picatinny standoffs. I used these before Charlie came out with his Davidson style one. I charge $135.00 to mount a scope. Worth every penny.
