    Knee pads. I’ve never taken my BCM 16” out to a 1000, it shot 3/4 MOA at 100 and I swapped it for a Wilson. It would, however, easily hit an 8” plate at 500. I love Hornady 75 grain. It shoots the best out of nearly all my 5.56 barrels. Semper Fi.

    What scopes are you all using for the long range steel?

    Cheers, Steve

    Moving over to the Precision section as it's more fitting.

    So it's not lost in the thread-my opinion-stick to one type of ammo for the class. No other student cares if you want to sit there as they watch because you want to try something else, re zero, etc. The exception is if you are well organized, have a plan and can gather data at one yard line and have another target to shoot at with the different ammo to see zero shift as the others do their exercise. Clear it with the instructor first and he/she may accommodate you.

    Have a small pack and stage equipment you will need, do not bring the kitchen sink, RV lounge mat and mini fridge to the line. depending on the class, you may not have your vehicle nearby and will "ruck it" from line to line.

    You do need basic items to assist with shooting drills, etc. I would advise contacting the school to see exactly what the curriculum is. No need to bring positional shooting aids if they aren't doing that. A rear bag is a nice item for prone or a pad if using a barricade, etc to rest the gun on. Shooting sticks are really great for rear support if kneeling, standing etc and front resting on tripod, window, barrier etc.

    What scope?

    In the end, a solid understanding of repeatable fundamentals, ballistics and reading/applying the wind is the key to success. Pay attention to those potions and you will be a happy camper. Note taking, data collection-take notes, don't let it consume you while shooting. I liked to use a small notepad and transfer it later if appropriate. Note all conditions so you can "repeat" them later. An example would be you are shooting at let's say 700 yards, it's sunny, hot and you ammo is cooking in the sun. You gather data and the next day you are at the same spot, it's cloudy and and you just pulled your ammo from the car which you took to lunch, had the AC cranked and wonder why you have a low hit.

    I would go "small/heavy fill" I use it on an AR or the AI, you can us eat flat, sideways or length wise

    small and light

    This is great and you can have gun data in it. A chart made from JBM Ballistis is a nice second-along with a manual density altitude chart

    JBM
    https://www.jbmballistics.com/ballis...culators.shtml

    Density Altitude, a good read-you can copy and print that chart-it will get you close. A summary-Density Altitude (DA) is the condition of the air the bullet has to travel through. Once you get it, you will understand and it's easy. JBM allows you to calculate different DA's and print so you have them available, laminate the chart or even retype it in a different format. Do it in 1000 increments. You will find that the DA doesn't change much until past 4-500 yards or so, caliber dependent.

    I made these from JBM, retyped. The .308 ones where green for MOA and tan for Mil, DA for my area -2k-+3k(Virginia) Have to reduce them for Florida, dropping the -2k, maybe -1k. The .308 's has a card for 2500-2650 DA. I would run a simple book as seen and then after look at a premed book like an Impact version.

    GET IN YOUR BUBBLE!

    What are the anticipated engagement ranges and target sizes?

    Choose a bag that has something where you can load the bipod is a plus.

    What glass are you running? I took my 16 inch Noveske out to 1,000 yards on sunday, the AR is just fine for long range. Fun to shoot and cheap to shoot.

    Follow the packing list from your vendor. Depending on the particulars of your course it should contain things like front and rear bags, bipod, mags, good glass, high quality ammo, notebook and pen, kestrel, range finder, spotting scope, ground mat, position adjuncts like sticks/tripod, etc, mags, if you're a clean barrel kind of guy, bring that stuff.

    If 70 TSX is the load you normally use there is merit in shooting it to solidify your zero and true your dope. That bullet is not typically a match load or known for best accuracy, so recognize that as you stretch out. You may find that your optic/barrel/shooter combo are better than the bullet - depending on who is loading your ammo and what you're doing with it. If you're handloading it and found a match-like formula, good for you and drive on.

    Share more info about your class, folks are always looking for places to train.
    Thanks for the rear bag advice gents!

    Rear bag? Sock full o' rice works for me. Rice goes in ziplock, then in sock, sock knotted closed.

    Airsoft BBs in a sock also works.

    Also- whats your opinion on the Magpul bi-pod?
    A sand filled suede is our "target" bag. It's a little heavy. A Triad Tactical is a decent option for faster applications, but it's lighter and not as precision oriented.

    Magpul bipods are good bang for the buck. I'd run one in a class. I do like the Atlas better, but Magpul is quite user friendly and functional.

I shot a long distance AR match recently and the 'open' division had some guys using 12" barrels out too 650 yards.
    Lots of great advice. I ordered a case of the IMI 77 grain Razor from Midway to save my my Barnes TSX. Got some more info from the instructor and he said we will shoot "small targets" out to 600 yards. So very confident the 18" stainless BCM with scope will do fine... heck qualified at 500 with no optics in the Corps lol. Looking at the Atlas Bipod now. Great info from everyone. Thanks!

    My cope is a 3-9 x 42 FFP.

    I have an old Harris Bipod and leaning towards using this and learning before I plunk down the $300 plus for the Atlas bipod. Will this work?
