    Lapua lot testing and barrel wear question

    I thought initially that this would not be necessary. Taking a light short approach would be sufficient however that has turned out to not be the case. We have to many bull shitters and wind bags on this forum. The information that would help you is being cluttered by these idiots. This will...

    Lapua lot testing and barrel wear question

    Well what you are saying here is nothing measured with air gages will ever be accurate? Previously someone said it was impossible to use air gages. That was Mr. IdealJoe at 9:04 on Saturday is that true? Then CNC equipment that measures dimensions to the millionths is not of any use here? What...

    Lapua lot testing and barrel wear question

    These are just a few things that should help the individuals that still do not understand. If the point is not made at this time then you must look somewhere else. There are more variable pieces of equipment that serve the same purpose from a very large group of manufacturers. Those you will...

    Lapua lot testing and barrel wear question

    There are numerous other systems that accomplish this as well. However not the particulate, flaws or finish evaluation. Those evaluations may be accomplished with different tests. Yes they are pricey. People just have to open their eyes and minds. They just do not wish to spend the time and...

    Lapua lot testing and barrel wear question

    I certainly have to give you credit for your persistence. Stubborn and lazy as you are egotistical at least you are not upset here. Absolutely nothing is settled science. The real answers are with people like justin and his ability to ask, "What if, what is and why"? If you wish to side track...

    Tim Tim Open Mouth and insert foot. This may get you started if you have the ambition. I am not here to try to impress you or anyone else here. This settled science and fact that all refer to is straight out horse shit. Try to start here and I can keep you going if you wish...

    Lapua lot testing and barrel wear question

    Tim, Tim, it is very evident you have absolutely ZERO experience in an inspection laboratory or machining or being a Tool and Die Maker. So why dont you just go and curl up in the corner and keep your mouth shut. Where you may be of some use is in your ability to shoot a rifle. Advise you try...

    The First Thousand Shots

    One of the things to remember here is that the groove to top of the land is only about .003 so the lead area is very small. Any small particulates would have an effect.

    The First Thousand Shots

    The equipment cost alone for a surface finish assessment and bore measuring devices would make it prohibited at this time. This is just a curiosity item where a person started to try a initial thought about the possibility of determining a small amount of accuracy variances on breaking in a...

    The First Thousand Shots

    Thanks for staying after the correct answers rather than idiotic assumptions. Question may also be is it possible a minuet amount of the glass particulates are imbedded in the interior of the rifling and stays there permanently? To an extent protecting the bore from the new abrasive? I have...

    So when we see a smooth barrel we should rough it up to a 200 finish again?

    The First Thousand Shots

    So what you are saying is a barrel interior must have a 200 finish and never be smooth to carry the lube?

    justin amature is working with barrel polishing from possible powder residue. Or what ever in the barrel changes to afford the change in the barrel for accuracy or break in. Plus the documentation to witness this process as best possible. I have never seen anyone else willing to work on this in...

    As for air rifles. You Sir, evidently have absolutely zero experience with them. Please gain some information prior to your answers. Pyramid air would be a great place to start.

    This is taken from 4-D Chamber Reamer Rentals. So you see chambers and cartridges can be all over the place. It is important to have ammunition that is compatible with the ammunition type, size and length, firearm action and type. Barrel groove and rifling dimensions must also be taken into...

    Not trying to get in the middle however. If they are proven facts then where are these proven facts? What and where is the verifiable documentation? We can all learn something new. Please help us in this process. Just for clarification: I do not normally update an older message. However my...

    The First Thousand Shots

    Great Justin. Looks like you have a nice little CZ barrel there so let her roll. What I have learned is there is a very minute build up of residue in the groove that is like glass in a short time. This seems to act almost like an accuracy enhancing deposit. Every time I have removed this the...
