Ballards may be weaker,
but they sure are neater!

Socket head screws will be a problem as there's not enough room to get a wrench into the head. Might need to cut the wrench down really short if you did use a socket head screw.

I have found that to be true. The casting sets I have done I normally try and use easily attainable common screw sizes for firearms. Unless I want to be absolutely true to original and then you have a hard time finding taps and dies for a lot of it to make the screws. Tried to make a few weird taps in past usually with dismal results.

I have a socket head screw in mine. no problems with it. I used a ball end allen wrench to adjust it.
