[QUOTE="jkupper, post: 874879, member: 61637"] I like the idea of this project, but I agree with the others that there are many variables that are hard to control, but I believe you may be able to do it. Here are some suggestions that I have. For your loads vs. the manufactured ammunition: - Factory ammo will come in unfired brass. Therefore, you loads should also be loaded into new brass. This may be cost preventative for you. - By being choosy in your factory ammo selection, you should be able to find a bullet that you can find to reload that is the same in type and grains. - Use the same primer as the brand of ammunition that you use. For example, if you use Winchester factory ammo, then use Winchester primers in your load development. - Powder generates a bit of a problem because you must change two variables to be safe. Changing type of powder is one variable, and changing the grains of that powder is another variable. It would be unsafe to pull a factory bullet, weigh the grains of powder in the load, and then use an equal weight of a different powder in one of your handloads. I do not really see a way around this issue. Maybe someone else has an answer for this. Rifle: - You need to have the same environment in your barrel for each shot. I would think that the only way to accomplish this is to clean your barrel after each shot, and then make sure that it is cooled back down to air temperature between shots. Shooting: - One of the largest variables in your experiment is you. You need to do everything that you can to remove human error from the experiment. If you can find a way to clamp your gun down for each shot, that is repeatable, you can achieve this for the most part. If you clamp the gun down too tightly you may damage your gun or scope, so I would think that the best thing to do is use a Lead Sled, and make sure your point of aim is the same every time. Try to touch the gun and setup as little as possible. Basically get it set up, on target, and then only touch the trigger if the rig is sturdy enough to do so. That's all I have. Some others may have other suggestions that may help. I'll let them chime in. Good luck with your project!!! Joe [/QUOTE]
