Followed the trajectory guidelines on the Federal website for a 100  yd zero roughly 1.5 inches high at 50 ydes when I got out to 100 I was 3 inches high  with 3 rds and to confirm that I aimed higher with my final two shots and they folloed up staying about 3 inches above point of aim.

Has anybody else ever found the information on the box or website to be that far off ?

I've shouldered Sad enough shotgun slugs to know that trajectory differs from one shotgun to another with the same slug.

The slugs with sabots are intended to be used with a rifled barrel. My rifled Hastings barrel shoots the non-sabot slugs more accurately than the plastic-sleeved expensive slugs. Trial & error is the rule here.

Well you can add Remington Accutip 20 gauge to the list  of ballistic tables that don't match real world performance.  According to their published tables the 20 gauge trajectory moves up .9 or almost an inch between 50 and 100 yds.  So as 100 -125 is about as long a shot as I would take with these,( they are the only slug my USH likes ) I zero'd at 50 to be 1 inch high dead center figuring to be 1.9 or 2 inches high at 100 well today I fired at 100  of a cold fouled barrel first group 2.5 last group 1.75 here's the rub they were 3 inches to 3.25 inches low and there was a little left to right spread caused by a 7 mph cross wind.

Shaking my head I went to the 50 yd range and fired three rounds all three were between 3/4 and 1 inch high so the original zero was still there.
