I went to the range yesterday to sight in my Remington 870 Express 12 ga. shotgun for deer season. I have a new factory Remington 23 inch fully rifled barrel with the cantilever scope mount. I was using a Bushell Banner 1.5-4.5x33 scope. I shot around $100 (50 or so slugs) worth of sabot slugs through it and it won't shoot worth a sh
t.
I tried-
Winchester Partition Gold- about 9 inch group @ 100 yds.
Winchester Platinum Tips- a little better but not much @ 100 yds.
Lightfield Hybred EXP- about 5 inch groups @ 100 yds.
Remington Premier Core-Lokt Ultra (only two rounds) they were about 2 1/2 to 3 inches apart @
50 yds.
All these slugs would hold tighter groups but there would be fliers that made them as big as they were. I'd shoot a 5 shot group and the first two shots would be really close then I'd get one or two that would be 6 or 8 inches away. This happened with ever brand I tried. The Lightfields were the best, but still not acceptable.
I used to have a 20 inch fully rifled barrel and a 1.5x power scope that used the mount that went around the receiver on this shotgun. Using the same Lightfield EXP slugs it would shot 2 to 3 inch groups @ 100 yds. all day long! Everything is tight on the gun!
I use to have this same scope on my 444 Marlin. I had a simular problem with that gun, just not as bad. I use the 444 for black bear and wild boar hunting. Having done neither I took the scope off and put it on the 870. I think the scope may be my problem. Today I put a Leupold VX II 2-7x33 Shotgun scope on it. I won't shoot it until tomorrow so I don't know if it has fixed my problem or not.
Have you ever had trouble with a scope???
