A little extra MV won't have that much effect. The reason a bullet has to be spun to be stabilized is because, in flight, it carries its center of pressure ahead of its center of gravity. That's like shooting an arrow fletchings first. It's a "statically unstable" condition and aerodynamic...

It shouldn't be too long before someone comes up with a composite barrel that's lighter and more durable than steel, plus it'll have harmonic properties to allow for vibration tuning. Composites is a field that's expanding at the speed of light. At first they'll be as expensive as Iranian caviar, of...

venison_burger, my BL-C(2) load, 30.8 grains, on average was 23 fps faster than my RL-10X load, 26.2 grains. That was with 32-gr Bergers. Unless your BL-C(2) loads were way, way light, I can't imagine the powder could have been responsible for any instability. Regardless, I'm glad it's shooting bett...

Sorry, I can't resist.

Yup, luvs me some 10x.

Carry your bullets in a cooler. I worked up my full strength .204 load (RL-10X) in the dead of winter. When I shot it in hot weather, they clocked >200 fps faster than when I worked them up. I know the original load didn't have that much breathing room, pressure-wise, which means pressures probably ...

I was having a similar "lean over and squint" problem with my portable loading bench, so I fashioned a shelf constructed like a simple box from some wooden trim, fastened to the bench with a small Irwin Quick-Grip, that elevated the scale to eye level. http://img151.imageshack.us/img151/36...

I think you're WAY too low. Unconfined gunpowder burns at better than 2700°C. Confine it and light it and it will get much hotter than that. Plain air raised to 60,000 psi probably would be hotter than what you're thinking. (can't find a formula at the moment to check)

You should check out this guy's homemade primer tests. Can't tell you how recent it is but the reason I even mention it is the Winchester magnum primer had the lowest SD, lower even than the purpose-built match primers. How's that for a kick in the shorts!

Works good, lasts a long time.

Banshee, increasing the number of shots in your groups isn't going to help until you can stabilize the rifle and you know all the difference is coming from the cartridge. Your aiming error compounds the bullet's ballistic error, and there's no way to tell them apart from examining the target. If you...

If you're seeing that much movement through the scope -- if it's not parallax -- I'm going to speculate either you need a more stable shooting platform or your benchrest technique needs work. Or both. One technique to help remove shooter influence is to shoot "round-robin," alternating loa...

I weigh (and segregate by weight) bullets and brass but only when I'm doing load development. One of my objectives in load development is to find an accurate load that's also tolerant of small variations. Provided I've done that properly, I shouldn't need to weigh any more when I start cranking out ...

Under no circumstances should you ever buy a used car (or a bridge) from any of the people who told you this.

With a stout load pushing the 39gr Sierra I have experienced consistent performance at 550 to 600 yards. I believe that bullet to be stable at that distance. Energy is doubtful even for prairie dogs, I would recommend shooting them in the head for a sure kill. A 39-gr SBK has @1000 fps has about 90...

Jim, I'd count that brag-worthy. So where do they put the rifle range on a pigboat?
