    Can I really be this bad?

    These are my thoughts as well. However, whatever worked it's way loose is a mystery. Everything was tight when I checked immediately after the POI shift. A curiosity: When you saw the Vortex scope die, did you ever learn what happened to it? What I can't figure is, if the scope is going bad...

    Can I really be this bad?

    Yes, I see that. Clearly I was missing a couple of measurements. I'm working to fix that. I picked my charge weights to work toward the right load. The idea was to test 5 loads, pick the best group, then use smaller increments around that weight with the next round of testing, to get closer to...

    Can I really be this bad?

    Thanks. Alas, I don't have another .308 to do any testing with. I'll have to figure it out with this one. I'm learning. I have two things to figure out; why did I get this massive shift in POI and why are my loads so different from the factory loads? My plan forward is to work with the...

    Can I really be this bad?

    It's a reasonable question. I do think I have the right bullet weight and type. I am going to adjust the seating depth based on recommendations I've read here and on manufacturer's websites. I'm not convinced I have the right velocity yet. Because I don't have consistent groups, I have to...

    I understand the confusion. It's a bolt action upper receiver on an AR10 lower. Definitely not the norm.

    Thank you for the info. The rifle is a bolt action. I will measure to the ogive and use that to set the depth.

    I'm not a meteorologist.

    I agree I have much to learn. What increments would you recommend? What do you do?

    Can I really be this bad?

    One more thing... No, I'm not measuring the amount of bumped back shoulder. I used the method of setting the resizing die initially with a factory load. Then I adjusted it until a resized case fit in the chamber easily. I got that method on this site. It doesn't tell me the exact measurement...

    Can I really be this bad?

    What we have here is failure to communicate. I measured the cases. All of the cases that were too short, I'm not using. None were too long. I measured the neck diameter. I guess I got the terminology wrong. What I'm seeing is about .003" difference between resized and seated bullet. I...

    Can I really be this bad?

    No, not set on the Nosler. It's just what was available at the time. I'd like to get some SMK bullets and will endeavor to do just that. At the risk of being attacked again, what do you mean by pressure signs? Flattening of the primer? Damaged casings? If that's what you mean, no. All the...

    Can I really be this bad?

    Um, maybe you missed what I said. I don't know why you think the powder weight is the only measurement. I may not be using the right terminology.

    Can I really be this bad?

    OK, that was no help. The resizing die was set up using a factory load, not just rammed through the die at some random set up. This is how Dillon recommends to set it up. The depth is not random. It's based on the OAL. How do you determine the depth you use? What is the point of...

    Can I really be this bad?

    Hornady's recommendation is 41.5gr - 45.9gr of IMR 4064. So, I made some loads to cover that spread to see how they would work in my rifle. Do you have a better suggestion? No, I have no chronographed them yet. Set my seating depth based on the factory cartridges. I resized the cases using...

    Can I really be this bad?

    One thing is sure, it's not the rail. Since this is an AR upper, the rail is one piece with the upper receiver.

    Can I really be this bad?

    I consider myself a beginner when it comes to precision shooting. I'm a lefty and I've always wanted a left hand bolt gun. I found Uintah Precision who makes a left hand bolt action upper that mates with an AR10 (LR308) lower. I bought a 24" barreled upper chambered in .308Win. Had some...

    Correcting for wind

    Thank you lowlight for those two very insightful posts. That's exactly what I was wondering and asking about. Learning that the wind has more affect on the bullet closer to the shooter helps me understand better. I hope everyone realizes that my OP was just a fiction about the equipment. I...

    Correcting for wind

    OK, I'm sure this subject has been hashed a million times, but I can't seem to find a concise answer. So yeah, dumb question.... You have your $500 rifle with the $2,500 glass on it. You've chrono'd your hand loads and know the exact muzzle velocity. You have a $300 bipod and a rear bag that...

    The next "Big Thing" or a concept soon forgotten?

    I figured it might be something like that. In the shotgun sports I hear people complain about lock time regularly. However, most of them don't even know what it is. In precision shooting, I could see it being an issue if you're able to move the gun prior to the firing pin striking the primer...

    The next "Big Thing" or a concept soon forgotten?

    Very interesting thread. I've just ordered one of these so, it's good to hear some are getting good performance out of them. I have a question about lock time though. Yes, the lock time will be slower on this style of action due to the distance the hammer must move and the separate firing...
