    Prone- Slung and Biopod

    This is my favorite thread/topic. I encounter novice F class shooters most everyday, who, having shot a few matches, thus think that that they know how to shoot. These folks actually don't know anything about good shooting. Most apparent, they do not understand NPA, muscular relaxation, and...

    F Class Competition - Guy beside me was dry firing 3 times before each round

    You need to concentrate on what you are doing. The shooter next to you is a distraction. Dry firing confirms smooth trigger control and proper adjustment of NPA but this exercise is practiced during the preparation period not during record fire, if the shooter wants to capitalize on a prevailing...

    AR Scope mounts.

    I have not experienced "way too high" from any of the AR unimounts out there except those designed to clear large objective bells over quad rails. Seems like most designs out there "get it", allowing for the full weight of the head to rest on the stock with eyeball squared to eyepiece for an...

    1,000 yards with 168 grn. 308

    The often misinterpreted issue is about M852, which was loaded with a 168, not getting to 1000 yards from a 22 inch M14. This non combat round was associated with Service Rifle Competition and worked well in that role for 200 to 600 yard events but was often seen key holing at 1000, thus...

    Prone shooting

    You are using muscle to get your sight picture. You are effectively using your shoulder muscles to maintain aim. Try this: Shoulder the rifle, allowing it to point where it wants. Do not steer to target. Your NPA will likely be somewhere off the target. Adjust NPA using entire body to get the...

    F T/R Competition I am really liking this rifle to help me read wind at 300 yards!

    The 75 grain AMAX actually only moves about a quarter MOA at 300 yards from a full value 5 mph wind, that's about 3/4 inch at target. Allowing for resolution with irons, I would not need to adjust my sights to still get a scratch X when holding good elevation.

    Odd sound from AR 15

    For awhile, the kid probably thought he was looking pretty cool, getting the opportunity to show he could close the bolt with forward assist. Might have impressed his dumbass buddies too that he was up to speed on AR shooting, at least until the disaster.

    F T/R Competition I am really liking this rifle to help me read wind at 300 yards!

    Here's an idea to make it all work as planned. Plot your calls and shots in your score book. Begin by annotating your starting no-wind zero and actual zero used for wind and weather conditions as presented from shot to shot. Record ending no wind zero. Use of the data book helps you see trends...

    Advanced Marksmanship Always wondered this; how far off the target is your reticle after getting settled in

    When I shoulder the rifle I do not let the target distract me, that's to say, I do not look at the target. I do not look at the target, to avoid unconsciously muscling to it while shouldering the rifle. If I unconsciously steer to the target I will not have a natural point of aim; and, it will...

    Odd sound from AR 15

    OP, What you describe is called a squib load. You must inspect the firearm after shooting a squib load since, when the condition is severe, the bullet from the load may not have cleared the bore. This can be catastrophic upon firing the gun again. I'd suspect contaminated powder, defective...

    Prone Hurts!

    OP, You do not likely have the sight/stock comb relationship adjusted to where you can rest the full weight of your head on the stock to anchor eye for proper sight alignment. The scope is too high, which means, for the eye to square with it, you must lift your head, thus creating neck...

    Opinions on Black Hills .308 vs FGMM? 5R Milspec

    My experience suggests there is no need for a 175 until you're shooting beyond 600 yards, that's to say, the ballistic advantage of the 175 does not become apparent until you shoot beyond mid range. So, since that load produces more recoil, making consistent control of the rifle more difficult...

    Opinions on Black Hills .308 vs FGMM? 5R Milspec

    In NRA mid range and LR match division, shooting 168's at 600 and 175's at 1000 from Blackhills, Federal, and Military match loadings, the best results have been with M118LR, pre production lot A. Overall, it appears that next to that fabulous concoction, Federal GMM 168's at 600 and 175's at...

    shooting beyond 500 yards

    OP, Start recording your calls and shots in a data book. Annotate all conditions. Eventually, you will be able to understand most every reason there is for the bullet not going where aimed.

    Help me understand my zero shift

    Could it have been the velocity in March was 2660 and then in July 2745?

    Help me understand my zero shift

    Temperature may have an effect on trajectory. Keep a data book to understand the effect. In general, a 20 degree temperature change is worth about 50 feet per second change in velocity; and, a 50 fps change in velocity has about a 1 minute value.

    How hard is it really to be accurate at 300-400 yards with an ar 15

    Training is key, mostly to come to an understanding for the importance of consistent sight alignment and SMOOTH trigger control. Of course, for good hits at 5 or 6 hundred yards some knowledge of how to counter for wind will also be important.

    Advanced Marksmanship best dvd for the expereinced LR shooter

    There is no substitute for just doing it. Long Range is about feel. The feel of being muscularly relaxed. Muscular relaxation is discerned from practice at building a proper position; and, when the shooter practices enough to get the position consistent from shot to shot he will also get...

    Advanced Marksmanship Holder over/off vs dialing

    Learn how to do it in all manner of possibilities. It should be obvious that dialing may be more accurate while holding or favoring may be quicker. Begin with the priority, speed or accuracy and improvise as necessary. Have a means to make accuracy quicker and speed more accurate. For example...

    How hard is it really to be accurate at 300-400 yards with an ar 15

    The full weight of your head should be "resting" on the stock and it should be in the same spot on the stock from shot to shot. You can maintain stock weld from shot to shot with a sling support which allows the whole body to move in integration with the rifle's recoil and return to battery...
