That’s fantastic, William. I hope this website inspires Other people to perform related exams. The set up was fairly straight-ahead. You simply want constant ammo and a good way to measure muzzle velocity, so the powder is the only real variable. Best of luck to you!
And also you’re in luck. Bryan Litz essentially did examination the has an effect on of annealing and neck stress in his new e book, which is able to start off transport in just a pair weeks. I had the priveledge of getting to proofread that chapter, and it is extremely exciting. I am able to’t give anything at all absent, but I'll declare that I used to be stunned by the effects.
A sensitivity research of strike share to be a functionality of temperature using WEZ Assessment would inform The story. When the temperature variation is important, then to fulfill your accuracy purpose need to utilize a chrono and do tests with the products at pertinent temperature(s).
SW MT I tried 8133 with a hundred and forty Etips in my 7mmRem. I ended up with scenario comprehensive and really compressed hundreds suitable off the bat. Like particularly audible crunch when seating a bullet.
Many thanks with the testing, I exploit H-a thousand a good deal, I ponder whether it is equally as secure since it’s also a Hodgedon extreme powder. Wonderful article
You're definitely receiving great velocity and accuracy. I might agree that there is little cause to jettison what you've with the newer powder.
Yeah, Rick it looks like we predict a lot alike! I do shoot at temperatures which are different than I zeroed, although I check my zero really usually … so I assume that boundaries that to some extent. I primarily shoot at 55-ninety five degrees ninety% of time, but when I’m looking that can be IMR 7977 as low as 10 degrees or in a summer season-time match, I'd shoot in temps as superior as a hundred and five.
Our assessments confirm that the Enduron powders are as unaffected by temperature as any powder might be. When you are a reloader therefore you shoot in a wide range of ambient temperatures, you owe it to yourself to try these IMR Enduron powders.
For that reason, we picked 5 distinctive rifle calibers to test all a few powders at the same time. This turned out to generally be A much bigger task than we had at first envisioned, but the final results ended up truly worth the effort.
Several things: A person is usually that soon after I purchased my own duplicate from the Labradar instrument, I spoke to get a time to the U.S. vendor, and he claimed he had completed the two-device examination with, IIRC, a nine imr enduron powders mm bullet. He stated the two models ended up in just one fps of one another apart from on the longest assortment, where by he would in some cases see two fps disagreement.
Cal, I deeply appreciate the operate that you just do. I wanted to weigh in within the LabRadar and MagnetoSpeed discussion. As far as precision I might believe that the MagnetoSpeed is the greater precise imr 7977 in stock evaluate in the Velocity from the bullet mainly because it exits the barrel.
That’s why I under no circumstances did a put up about this. Really to succeed in any common reality you’d require to test in excess of various a lot of Each individual primer And that i just don’t have the time to do that. It’s be Yet another appealing experiment!
With all the LabRadar, it’s easy to simply document almost each and every spherical you fire with the range. So I from time to time document fifty shot strings. I almost never see a major distinctive in SD from 10 pictures to fifty shots. They sometimes do range (mainly because it’s often merely a sample of the population), but to me 10 pictures may be the minimum amount I need to draw major conclusions from.
Yeah, I used to be a giant supporter of 8133 myself. It genuinely sucks not obtaining it any longer. Perhaps there'll certainly be a big enough backlash that they will obtain Yet another place that may make if for them. Standard Dynamics may have a lock from the recipe though and It really is attainable no-one else will make it.
