In easy conditions a policeman employing a radar gun would need to get directly before the approaching car or truck to have the most correct measurement of speed. Any motion to the best or still left would reduce the displayed velocity.
The other issue is a question: Was the two fps reading through distinction with the Magnetospeed continually higher with the Labradar? 5-6 a long time ago, a retired radar engineer who experienced produced a Doppler device for his personal use shared some output from it with me that he’d manufactured shooting a forty S&W pistol. Its output was a continual velocity vs. time plot rather than velocity vs. distance. It confirmed some thing Harold Vaughn had demonstrated which has a magnetometer rig in his book, Rifle Accuracy Details, about 15 yrs prior to him, and that's that above the 1st couple calibers of bullet journey past the muzzle, muzzle blast even more accelerates the bullet just a little.
They have not taken them off their Website and possess no point out of them getting discontinued on web page? In which you hear this? I googled it and only issue that arrives up is this article?
The Kestrel Elite Climate Meter with Utilized Ballistics means that you can enter a desk of muzzle velocities for various temperatures, and it will quickly use that details to infer your Original muzzle velocity for The present ailments. That could be a really amazing feature, and as far as imr 7977 in stock I comprehend it’s the only real ballistics engine that provides a means to mechanically account for such a variable. Nonetheless it’s only precious Should you have great details to assistance it.
I started off at 58gr and labored nearly 60gr. Wasn't positive the flat dependent Partition would develop a lot more stress as opposed to Hornady bullet so I stopped there.
We’ll view the outcome in a couple of various ways. Let’s get started by simply checking out the general variance in muzzle velocity we measured about the complete array of temperature extremes:
I two other OCD handloaders which i’m excellent pals with run from the exact same experiment. One of them wound up with the identical purchase as me, and I feel the opposite one particular (who was basically Patrick, the male who did this powder examination) stated the Sellier & Bellot primers produced the lowest SD’s for him, imr 7977 in stock but CCI was appropriate guiding them.
This check was carried out by Patrick Middlebrook. Patrick is excited about the art of precision rifles. He’s a fantastic shooter who's got competed in several community matches, and several countrywide PRS matches. He can be a 5-star handloader. I’ve uncovered a ton from him!
The imr 7977 in stock purpose of the discipline test was to quantify the temperature balance of the popular Hodgdon H4350 and Varget powders and Examine People to IMR’s new Enduron line of powders. To do that we very carefully measured muzzle velocities of meticulously loaded ammo above a large selection of temperatures.
That is a superb issue, Martin! I hadn’t thought of that, however, you’re Definitely suitable. There exists some price to your powder Use a predictable, linear improve in muzzle velocity.
It will probably be attention-grabbing to find out if any of The brand new RL powders start out acquiring some notice and use. RL16,23 and 26 are alleged to be temperature stable.
Instead of state “ten shot groups can precisely describe the actual distribution of photographs” point out From ten shot teams along with a acknowledged or assumed Typically likelihood distribution you can determine a great estimate of the mean with the team.
……”missed the importance of a temperature stable primer.” You men just blew my head! Also interesting that Varget did much better at decrease temps. Though H4350 was better in the upper areas.
