    Hello I have a Remington 700 adl I have a vortex diamondback scope on the gun and I am having major issues sighting this gun in. I free floated the barrel on the gun and have tried different ammo but am now using rem core lokt 150 gr. Which I have had success w in the past. I'm not sre what it might b but seems like wen it warms up the bullet goes way off my left to right stays on close but up and down moves about 4-6 inches sometimes up sometimes down and this us at 100 yds its driving me crazy and ammo is not the cheapest thing ever. I was shooting the gun in a vice don't no if tht may have messed something up or the free floating I did or wat? Any help would b amazing I have a deer tag to fill in a couple months and gotta be dead on where I hunt u expect to shoot at least 200-300 yds on average and Im not even confident at 100! I have also checked tht everything is tight as well. Thanks Bri

    Do you have a 2nd scope to try? Seems like you have taken care of the other obvious things.

    I don't have a second scope at this time but did contact vortex ( who's customer service was awesome!) and they sent me a shipping label so I could send in the scope to get it checked out to see if that's my problem .. I just don't feel like it is and feel like I've covered other bases as well and didn't know if all rifles shoot well with a floated barrel or if maybe I messed it up by doing tht or any other ideas .. Thanks for the reply!! I appreciate all help and suggestions!

    What warms up? the barrel or the air temp around you?

    WOW at those temps I'd recommend shooting ONE (1) round every 20-25 minutes!!! You could shorten this time way down by shooting 1 round, placing your gun in an airconditioned vehicle for a few minutes with air blowing on barrel, until cold, same temp as 1st shot....It sounds to me like you are way over heating the barrel and then the rounds just "walk" all over the place, most times in a rough kinda circle motion????Hope this helps it really sounds like the trouble in my opinion,,,just from reading your post?????

    Also I do not like vices...they impede the natural twists and vibrations of the firearm from the stock and the barrel..the vibrations are so fast that a vibration "wave" goes the length of the barrel and back several times BEFORE a projectile can exit...vices changes all that..

    I was kinda thinking maybe the heat was a factor but didn't know how much heat would affect poi. And ya I'm not to crazy about vices either but couldn't make it work without a vice so tried it with one and still did not work. What do u think about glass bedding ?? Has anyone had any issues sighting tht were fixed with bedding?? Or think it might work for me ?
