While working on the trigger adjustment after installing the Rowan trigger blade, I had the stock of my R7 off a bunch of times.
Despite having a Brownells screwdriver set with about 50 different tips, I managed to slightly mar up the slots of two of the three screws/bolts that hold the stock and trigger guard on. In my defense the rear trigger guard screw and front stock screw have a real shallow slot. I kept thinking, "I wish those two had a deeper slot like the front trigger guard screw has".
Well, after shooting today I noticed that I married up the deep slot screw as well the last time I had a screwdriver to it.

Went to Ace Hardware and spent a few minutes looking through their black Metric bolt section and found Allen head replacements for all three.
I might try to polish and cold blue the heads. They aren't bad as is, but could be better if I blue them.

I use a T-handle inch/lb torque driver, been setting the rear TG screw to 14 in. lbs., the front TG screw to 38 in. lbs. and the stock screw to 22 in. lbs.
In the thread I did about my R7, I noticed a pic a member provided of his HW80 that he had fitted a TX200 trigger blade to. His rear trigger guard screw is an Allen head one.
So I must not be the only one that wanted to get away from the shallow slot screws.

I could buy factory replacement screws from AoA for around $9 each, but they would be the same slotted screws that I don't get along with.
The 6mm front TG screw was $1.79 and the two smaller 4mm ones were .79 cents.

This morning I was shooting the 7.87 JSB and the 7.33 AA Falcons at these little stick on dots, meant to reinforce a page with binder holes.
I can usually keep all my shots hitting in the dot, and if I really concentrate, can put them in the center hole without hardly touching the ring.

This is my best group yet, 5 shots @15 yards. I measured .130" CTC spread. The 7.33 gr. domes sure rip up the paper compared to the wadcutters.
I was getting used to the nice clean hole of the Vogel wadcutters, but they don't group like this.

I take a ping-pong ball-sized lump of duct seal, work it until it's nice and soft and then flatten it into a thin (1/16") pancake. Press it to the back of your target paper right behind your bullseye. It will stick to paper especially between the target and a piece of cardboard and gives you wadcutter-like holes with domed pellets.
