DaveT Posted October 14, 2015 Report Share Posted October 14, 2015 Could kick myself sometimes! Recently had to do a very quick zero and get drop tables for my AR prior to my first CSR comp. Went to a local farm and used a table to get enough elevation to clear obstacles to target backdrop. Lesson #1.....plan ahead and allow time! To get an accurate zero I used a front rest and settled the handguard on it. Got a great / accurate zero and then 200 yard & 300 yard drops using same setup. Shot the CSR match and noted that most rounds were going low by a good 1 or 2 MOA when prone....put this down to my nerves etc first time out. Tried the AR again today Mag-rested as per the CSR match prone stages ....guess what ......it shoots much lower than when rested via the handguard.....Doooh! Lesson #2 (re-learned beginners stuff....no excuses!) .....always zero with the same setup you intend to shoot with! The added 'wrinkle' here is that when NOT mag-resting the rifle in prone (IE sitting , kneeling shots etc) it shoots to the same zero as when I rested it on the handguard.....so I will need to revisit my drops to note what I get regarding differences between prone (mag rested) and positional shooting. All my previous target shooting has been prone with bipod (IE always a consistent setup) ......its too easy to forget changes induced by positional shooting. We live and (hopefully) continue to learn!...That's what makes it interesting. Link to comment Share on other sites More sharing options...
