Hello all!
as some here may recall I bought my boys a Rossi combo rifle .243 win/.22/20GA, a wile back.
I just threw some mid range loads together with some Condums, .75 gr sierras and a lighter end charge of 4350. They shot fair enugh for break in of gun and shooter.
So when at the local gunshop I bought some Speer 85grBTs. As I was low on 4350 and had plenty of 760 I put together some test loads with that.
At 25 yds all was okbut not great , at 50 1" groups, at 75 yds 2 1/2 groups, and at 100 yards I could not even hit the 15"ish X 24"ish box (12 shots) and not a mark! I could see dird kicking up all over the place.
I thought the scope came loose , or loose screw etc. But all was well with the gun.
I shot some more of the 75/4350 loads and they were back to their 1"ish groups.
I cant belive the 760/85 grBTs loads were that unstable that they went that wild at about 75-100 yards!
I have had some bad loads when I started casting for rifles but man not that bad!!
