[QUOTE="westcliffe01, post: 884056, member: 35183"] To provide some constructive criticism instead of just bashing, I suggest you take a look at the ballistics calculator hosted right on this site (G7 Ballistics Calculator) about in the middle of the menu bar near the top of this page. You have to register/create a login. Then you have to figure out the details for the load you were shooting. Muzzle velocity, weight of the slug, G1 or G7 BC for the slug, weight in grain etc. Plug in environmental conditions for the day. You can then save the load info (give it a name that makes sense) as well as the environmental conditions. I do not know the load you were shooting, so I ran the numbers for my 50 cal muzzle loader shooting a 250gr Hornady SST bullet that is a 45 cal in a sabot. I put in that it was sighted in 10" high at 75 yards. Then I ran the ballistic calculation and after it is run, I changed the range increment to 25 yards and total range = 300 yards. That is good enough for a case like this. If you look at the attached calculation (valid for my load and typical Southern MI hunting conditions) you will see that 10" high at 75 = 14.3" high at 125, 15.3" high at 150 (apogee, more or less) then starting to drop, but only reaching the point of aim at 280-290 yards. By comparison, if the same weapon is sighted in 3" high at 75 yards, it is 3.2" at 100 yards, 2.7 at 125, 1.3 at 150, -1.1 at 175 and -4.6" at 200 yards. Sighted in 2.5" high and you will have a point blank range (+2.5 - -2.5") of 175 yards. So, ignoring technique, a slug gun that is sighted in 10" high at 75 yards, is not sighted in worth a ****. Not for practical purposes. [/QUOTE]
