    Cold Bore Shots, POI Shifts, and Canted Scopes

    Update: Torqued everything down Friday and went out and shot 15 rounds at 100, and was able to confirm I was hitting 1.75MOA hit with good left right. Re-zero'd and was good to go. Next morning, my first shots were at 200 yards. Dialed my dope for 200 yards and while my elevation was good my...

    Cold Bore Shots, POI Shifts, and Canted Scopes

    Youre right, that I can do. For that process, do you recommend backing out one screw on the ring at a time and retorquing it to manufacturer specs or backing out all the screws on one of the rings, while leaving the other attached, and then retorquing them down together? And do you think I...

    Cold Bore Shots, POI Shifts, and Canted Scopes

    On another note, what process do you guys recommend for cleaning and retorquing all the screws? I read @Formidilosus post from 2017 about removing all the screws, wiping them clean, applying blue loctite, and re-inserting and torquing to specs. Manufacturers say to torque to around 18in-lbs and...

    Cold Bore Shots, POI Shifts, and Canted Scopes

    Because I am shooting in a match with some people on saturday and I already put together a dope card for the ranges ill be shooting at. Im worried if I take off my scope, rings, base, etc, and retorque everything I may not have the same or accurate adjustments. I'd rather keep what I have for...

    Cold Bore Shots, POI Shifts, and Canted Scopes

    I should be able to confirm zero on friday. After my shoot on saturday I will likely take off the scope and check torques on rail, rings, ring to scope, action screws, and re-level my scope. Nothing I can do about inconsistency from lot to lot for factory ammo but ive had good luck with the...

    Very true, couldn't imagine it would be a 2moa shift though could it?

    Cold Bore Shots, POI Shifts, and Canted Scopes

    I had not cleaned my barrel since the last time I shot it. However the rifle had been sitting for awhile and it is possible some dirt or debris somehow got in the barrel or did something that caused the round to shift, not likely but a possibility. I have not had a chance to do the tall target...

    Cold Bore Shots, POI Shifts, and Canted Scopes

    The shots at 200 - 1000 im referring to are for the shooting competition im participating in on saturday. I will be trying to shoot 10 rounds to confirm zero on friday after work, and if I have time another 10 rounds out at 600 or 800 if I can get a target set before sundown, otherwise I will...

    Cold Bore Shots, POI Shifts, and Canted Scopes

    That is precisely why I want to gather as much info as I can because at $3 a round i dont want to be wasting shots that im not gaining any useful information from. If im seeing consistent scope shifts I may upgrade to a Tenmile. I will see on friday what my 10 round group at 100 is and ill...

    Cold Bore Shots, POI Shifts, and Canted Scopes

    Seems to all come back to confirming my zero. Ill see if I can pickup an extra box of ammo and do a 10 round group at 100 friday night and be able to check to see if there is a cold bore shift or not. Rifle is a Christensen MPR. I know theyve had QC issues but my rifle has for the most part...

    Cold Bore Shots, POI Shifts, and Canted Scopes

    Yea ive heard of some of the issues vortex's have had, ive considered it a possibility but only way to confirm is to dial out to the previous dopes I got at 400-1000 and see if its its still hitting, that as well as shooting it at 100 again to see if the zero has changed at all

    Cold Bore Shots, POI Shifts, and Canted Scopes

    Ill have to double check scope ring torque specs. Action and base were mounted at factory and I havent touched them. Scope is a Vortex Strike Eagle 5-25x50 FFP All my shots were on freshly painted steel at known ranges, 200, 300, 409, 570, 796, 999. Was able to get repeated hits on them. Ill...

    Cold Bore Shots, POI Shifts, and Canted Scopes

    Yea ill have to just put more rounds at 100 to be sure. Im fairly confident it is zeroed at 100 based on past shooting sessions and that last three shot group, its just those two initial rounds that threw me off, especially because I did not adjust anything after the shots and then it ended up...

    Cold Bore Shots, POI Shifts, and Canted Scopes

    For the inputs on the BC ive tripled check them. What are the major contributing factors that could cause that? BC is correct Scope height is correct Bullet diameter and length Using Density Altitude, at 3400' elevation and 60F I get about 4000' DA Barrel length and twist set properly The only...

    Cold Bore Shots, POI Shifts, and Canted Scopes

    In the past its been all good, most shots in the bullseye, any misses were due to shooter error, flinching, and maybe barrel heat up. I only had 35 rounds to shoot that day and needed to shoot out to 1000 to confirm dope because we have a little long range shooting competition between some...

    Cold Bore Shots, POI Shifts, and Canted Scopes

    Yes, my first shot through the rifle, cold bore and all, no cleaning, was 2 MOA high. Made no adjustments, next shot was about 1 MOA high. Again made no adjustments, next 3 were all in the center under 1 MOA group size.
