I told you guys I'd report on progress. I'll start with the bullet. Tumble lubes in Lee Liquid alox they whiegh a consistent 52.5 grains give or take a line on my Lyman scale. The Lube grooves are so small that they will fill up with lube if one tumbles them long enough. I consider that a pluss I guess. I didn't wiegh everyone that I loaded but did visually inspect them paying particuler attention to the base. I found very few defects. They are out of round .001 miking .224-.225
The brass - I started with 11 once fired Winchester brass; full lenght resized. My old die in the past had gotten pretty scratched up. I had vigorously polished it to remove the scratches so my brass doesn't get resized as much as normal. They have a “feel” being chambered which has never hurt anything. I trimmed them to 1.695 which was the lenght of the shortest one of the bunch. Remember I said I was cheep so I didn't buy a 22 cal neck expanding die. The expander ball of the sizing die measures .223 so I had to figure out a way to seat the bullet with out shaving lead. I adjusted my 6.5 neck expanding die so that it would just a eeny bit start to bell the neck. I seated the bullet to the crimping groove, crimping them to remove the bell. I measured the neck diameter before and after seating the bullet. Some of the necks gained .001 in diameter; some of them I couldn't measure any difference. In either case I didn't see any shaved lead.
I started with 3.5 grains of Unique. Shooting through a clean lightly oiled barrel at 25 yards the first shot went low. The second a little higher. The next 4 went into a small dime sized group just below the aiming point. The next 2 went 1-2 inches high and 1-2 inches left and right. The last 3 went back into the group. Where did those 2 wild flyers come from ? I had been elevating the muzzle of the rifle to get the powder near the primer. I thought maybe I had forgotten to elevate the rifle.
To eliminate that possibility I reloaded again this time using a 1/2 grain tuft of polyester quilt batting to keep the powder in place. Again shooting through a clean lightly oied barrel to keep things equal I had the same results with the first to shots. A nice group formed then flyers. I'll attach a picture of the those targets. If I can figure out how
To sum it up; the load shows potential to be an excellent squirrel load if I can eliminate the flyers. I'll experiment some more
I might add that the rifle will shoot under an inch often getting dime sized groups at 100 yards with good jacketed bullets so I trust the riflle. It is equiped with a old Leupold m8 6x scope. I never shot the gun much before at 25 yards. Could the scope have that much parrelex ? I'm not sure what parrelex is exactly but I don't figure the scope is adjusted for 25 yards.
i went through all of this with my Model 70 6.5x55 and could shoot squirrels with it but it isn't legal to use anything larger than 22 cal for small game here in Pa. My 6.5 also has a Leupold scope showing no proplem at 25 yards.
