That is an excellent post! I hadn’t ever found that. I've a buddy who is inside a capturing club with Speedy Gonzales. He certainly knows quite a bit about the benchrest earth! Thanks for sharing.
That said, with more than enough samples the histogram of the samples may possibly counsel a likelihood distribution purpose.
The opposite thing is a matter: Was the two fps reading difference Together with the Magnetospeed persistently better for that Labradar? Five or six yrs in the past, a retired radar engineer who had created a Doppler device for his personal use shared some output from it with me that he’d designed taking pictures a 40 S&W pistol. Its output was a steady velocity vs. time plot rather than velocity vs. distance. It showed one thing Harold Vaughn experienced demonstrated having a magnetometer rig in his reserve, Rifle Precision Information, about 15 years before him, and that's that around the primary number of calibers of bullet travel past the muzzle, muzzle blast further more accelerates the bullet a little.
To make sure that’s a big difference in POI of 15″ at a thousand yards, just from leaving the round during the chamber for an prolonged length of time. But, like I mentioned right before, I’m not sure you should be capable of warmth the powder each of the technique to one hundred forty° File dependant on the chamber temperatures I recorded in my recent exam. But there are numerous variables at Participate in that it's at the very least plausible.
Additionally they are formulated to get temperature insensitive, similar to what we’ve found with Hodgdon’s Extraordinary series of powders.
You happen to be definitely receiving high-quality velocity and precision. I'd agree that there is minimal reason to jettison what you have got for the newer powder.
Will not attempt any of your procedures or techniques shown or described on this website.

IMR now presents 4 Enduron powders that address a wide array of burn off premiums. These are ideal for lots of cartridges, from compact varmint cartridges each of the way up on the .338 Lapua Magnum.
Loading density is perfect for magnums, nicely filling the case at greatest prices, contributing to outstanding uniformity and precision. The 7mm Remington Magnum “never ever experienced it so good”!
1 fps or 0.01 fps? Wouldn't it change the group precision at 100 yards in any respect? Would it not change the SD from the muzzle velocity whatsoever? Visit the array that has a specified rifle, ammunition, sighting procedure and System and establish the group precision at a hundred yards, signify muzzle velocity and muzzle velocity SD for any specified ambient temperature. Then all particular person consequences which include effect of temperature on powder and any effect as a consequence of thermal enlargement or adjust in physical properties are “included” within your measurements. This is the typical engineering solution but degree pf applicability of outcomes to other rifle-ammo-sight-System techniques might be tiny recognized at most effective.
