Never planned on using it but finally i got tired of the bag being empty and so i filled it up with sand. It only added 7lbs but 30lbs overall with the lead sled weight included. I really havent shot it off my shooting table yet so i dont know if i will notice the extra 7lbs or not.
One problem i ran into was the bag got in the way of the elevation adjustment.
Apex with the 245gr Powerbelts, 90gr BH209 @ 100 yards. Highest shot was on a recently cleaned bore.
On the line accuracy to say the least LOL.
