I've been lurking on the site for several weeks, I'm new to Handi's but have been around guns all my life and have done quite a bit of my own repairs and gunsmithing, been handloading 50 years.
My handi was purchased used in a .223 Rem with plastic stock, wouldn't shoot for beans. So following the several FAQ's on the site finally payed off today. Just returned from the range with a smile. Discovered that little gun really likes a Win/western case, Win 6 1/2 primer, 23.7 grains of IMR4895 with a 60 gr Sierra set .010 off the lands. Forend free floated from the attachment screw forward, and a .0015 stainless shim at the pivot point.
Four shots in .487, two in the same hole that took a magnifying glass to detect. Not too bad for 69 year old eyes.
Thanks again
