slug gun question
 

i sighted in my new H&R 20 ga. tracker 2 sunday, and it is zeroed at 50 yards. now i looked at the box of the hornady sst's that i am shooting it, says that it should be 2.5 inches high, will that through me off with these trajectories or will the 100 and 150 and 200 be 2.5 inches less?

If i understand the question, (which would be easier if there was some punctuation between sentences) i think your gun will shoot low. But not necessarily 2 1/2" low.If you go with a 50 yard zero, you should check the drop at longer ranges.

RE: slug gun question
 

ok fixed the punctuations, al right i will try them at longer distances.

RE: slug gun question
 

Never go by the box, always try them yourshelf so you know where they will hit and your comfort zone to make a good shot.

RE: slug gun question
 

+1 for sinocs, the ballistics on the box are based on a test gun which usually has a longer barrel than most hunting guns. You have to find out for yourself where your gun shoots.

RE: slug gun question
 

ok i never knew that the gun they tested had a longer barrel, ok i will try them the next time i get a chance at longer distances.

RE: slug gun question
 

First look at what your average shot is going to be and zero to that distance. I'm assuming you've done this and that is why you sighted in at 50yds. Next I would do what the other guys in here have said and see what you gun does with these slugs at 25,75,100, 125,150, and 200yds. Personally, I'd have trouble justifying an ethical shot out past 125 with a 20 gauge but your little gun may shoot good groups out past that. The only way to know is to try em at the range and see what ya come up with.

RE: slug gun question
 

why do you call it a little gun? andno i have never done this that is why i ask;)

RE: slug gun question
 

didn't mean to offend you by saying "little gun". I still stand by what I suggested earlier

RE: slug gun question
 

thats ok i understand, i was just curious why ya said it.

Alright let's look at the trajectory chart Hornady provides for the 20 SST ..........

If you are sighted in dead on at 50 yards, ignore the -1.5" muzzle number - just forget it.

All that you need to know is that at 100 yards your point of impact (POI) should be .8" higher (call it1" to simplify it).

At 150 yards the POI should be 2.5" low.

And at 200 yards the POI should be 10.7" low.

IMO, according to this trajectory anything at 100 yards to 125 yardsis a point and aim deal and all the blame of a miss or bad shot placement is on you.

But the drop numbers over 150, when figured in with windreally stretch the odds of guaranteed lethal shots not to mention the energy falling off so quickly past 100 yards.

RE: slug gun question
 

thanks for all the input guys.

RE: slug gun question
 

No. IF you have to zero +2.5" at 50 to be dead on at 100, and you zero it dead on at 50 instead, it will be over -5" @ 100, as the range has doubled. Bullets drop much faster in relation to the line of sight after they cross it dropping! So your slug would be close to -15" at 150 yards, and over 2' low at 200 yards. Shoot these distances, you will see what I mean!
