Hello all. I am new to the forum and just getting into the idea of long range hunting. College guy on a budget. I am from Southern Idaho so I am wanting to be confident taking 300-500 yard shots for desert elk/mule deer. Most of my deer hunting so far has been in the 100-200 yard range so I haven’t had any issues so now I am just wanting to extend my range. I’ve slowly been building up my set up with a Ruger American 30-06. I was able to snag a 4x16-44 MOA Vortex Diamondback Tactical before they went on backorder. The hollow, light stock in the -06 was beating the crap out of me so I have added weight to the stock which took care of that problem. I also added a bipod. With a 165gr Sierra Game-Kings I shoot 1-1.5 inch groups with some under 1 inch on rare occasions, usually depending on how I’m doing on the particular day. So I have some questions about a few different things. I shoot good groups at 100, 200, 300 yards. Precision (acceptable for hunting imo) is fine, however accuracy is not. Know knowing theoretically at 200 yards my SGK drops 3.8 inches and at 300 yards it drops 13.8, I dial my elevation accordingly with a 100 yard zero as well as adjust parallax at each range so the reticle doesn’t move on the target. This is with little wind. With each 100 yard increment my bullets impact farther to the right and up of my aiming point. About 2-3 inches at 200 yards and about 8-10 at 300. So.. My scope was mounted and torqued level at the local gun shop. I have double checked it, so the scope to my knowledge is level so there shouldn’t be cant. I do my best to make sure the scope is level at all times. However, does anyone have experience with the anti-cant bubble levels? Are they installed easy? I have worked hard at developing better trigger control as that was an issue for me at one point. I have the trigger set as low as possible, 3lbs. Since I shoot good groups at 100 dead-on I have a hard time thinking its me pulling. I have a known astigmatism in my right eye and I shoot right handed with a righty set up. Probably not ideal. I found this out after I purchased the rifle as I have always shot every gun right handed. Does anyone have experience with this? Could it have something to do with my POI being off to the right at longer ranges? Would it be worth making the switch if so? Any input or constructive criticism would be appreciated. I’m sure I will have many more questions as time goes on as I am just a greenhorn when it comes to this. But hey, we all have to start somewhere. Thanks!
