    Best Vehicle for Precision Rifle Guys?

    Commuted in the truck and after 6 years had over 200k miles. In great shape, the sales value did not reflect what it was worth. So the soul-train bought me 4 years of low miles on the Tundra which has gone down to Fla fishing and up to Newfy, NM, Co, SD to hunt. Tundra is back on the road full...

    Best Vehicle for Precision Rifle Guys?

    To save putting more miles on my 2008 Tundra I've been driving a Kia Soul four years. Great room in the boxy hatch back, good mileage, sporty drive. But after four hours my old fat ass is acheing, and its going up for sale. I'm back in the Tundra for comfort, and don't care about the 17mpg. With...

    Advanced Marksmanship Shooting Mental Program.

    Once you have your mental checklist, its great to incorporate the entire routine into a dry firing exercise at home to also reinforce it into your muscle memory. Last year my Ftr scores were subpar for several reasons. This year the rain was abysmal for several weeks before the first match, so I...

    F T/R Competition FT/R and 80SMK

    For three years now I'm running the 80.5vld at 3000fps in a 26in barrel using cfe223. Nice node below any pressure issue. While not temperature sensitive I cooked off one shot that blew a primer in max summer time last year so I'm careful in that regard. With a wide node I will decreases .1gr as...

    POI rises, velocity doesn't. I'm baffled.

    So the 223 changes 1 mil (3.5moa) at 400yd during a given shooting session? My 223 drops 1.7 mil at that distance and the ballistic calculation only varies .1 mil due to daily temp increase. Something is very wrong to cause 1 mil change in this situation. I'm shooting in your area and have not...

    The Value of Dry Fire

    A little different dry fire routine to try. Setup in a place where there is nothing to aim at except a blank wall. Why? You will focus totally on the minute details of body positioning, cheek weld fit, length of pull, scope alignment, etc. Due to a period of lengthy rain I did this before my...

    G1/G7 Discrepancy

    If you look at a wide array of bullet diameters and weights there is a perfect correlation between G1 and G7 values, so they both portray identical information. The difference in the ballistic calculations lies in the drag curves which the BC references.

    Low ES AND SD but still bad groups ?

    Unless you're entering a contest for ES and SD, forget the chrono and use the target to define the node. Barrel harmonics and the associated compensation define the node. After that is done then use the chrono for characterization and improvements to loading technique.

    Rifle Scopes SWFA 10x42; 12x42; 16x42 & similar priced optics

    I have the SS in 12X, decent scope without any problems for the three years I've owned it. About two years ago I acquired the Argos BTR 6-24 FFP which I normally shoot on 15X, and steel at 1000yd is more clear than the SS; I'm not talking about the snob-type image version where you can read...

    What's best for me ?

    All phones I know of have a built in barometric pressure probe. Ballistic apps can reference this for accurate BP, you only need to provide temperature.

    Node question

    Google Chris Long Optimal Barrel Time, and Audette Ladder Test. They fit in with the OCW method noted above. Also Varmint Al has a detailed discussion about harmonics, and how tuners work in conjunction.

    Advanced Marksmanship Please school me on QUICK wind reading (match skillz)

    Same method I've used a few years. This works for all my rounds and the only thing you need to remember is the wind speed per 0.1mil; 5mph for my 223 and mph for 6.5x47.

    Full length sizing

    When the handle on your press is in the down position, how long do you hold it there? Variable time = variable bump. Measure a few brass with increasing dwell time, and by running the same brass a few times through the die while its in the shell holder. One of these will provide more consistent...

    A Brand New shooter: What should I be using for trajectory?

    I have used a few, and out to 1000yd the results are virtually the same. I will suggest Strelok Pro for several reasons. It has a decent instruction, faq section. The built in data base includes the details for loaded ammo as well as bullets, so use this as a starting point for velocity and then...

    Rifle Scopes Thoughts on poss. selling Vortex Gen 2 4.5-27 for Cronus BTR 4.5-29 & XLR Element chassis

    You can invest as much as you want in a scope. I shot comps with a kid who often won, and he used a $150 Bushnell Elite 10X past 1000yd. He has subsequently upgraded but doesn't shoot any better. These days there are many scopes that will achieve your needs quite well, while the debates over...

    How accurate is your rifle at 100 yards

    I shoot Ftr which requires an attached bipod. F Open is off an unlimited rest. All prone. Doesn't matter, very few 20 shot 0.5moa records regardless of class or equipment. My point was 0.5moa all day long claims are meaningless, have no definition, and are generally BS or the record books would...

    How accurate is your rifle at 100 yards

    I don't think that matters much to those who claim 0.5moa all day long. But the options are wide open since there are very few 20 shot Xring (0.5moa) records.

    How accurate is your rifle at 100 yards

    Those who can shoot 0.5moa all day long should shoot some Fclass matches and set new records for the world to chase.

    Magnetospeed vs Calculated MV

    I know you're concerned about a consistent 1moa bias. In general I'm amazed the ballistics work as well as they do using a bc to represent a specific bullet vs a different projectile from which the calcs were trued. Being able to true within an app after a few range sessions and subsequently...

    F T/R Competition What stock should I use?

    I have used both a Manners T4A and a custom stock on my Ftr. Now it wears a Choate Tac stock which has a full length aluminum bedding block (into the forend for bipod support). With extra spacers for length, and the tall cheek rest, it fits me perfectly as do the other two I use. I am sticking...
