That’s good, William. I hope this Internet site inspires others to perform comparable tests. The setup was fairly straight-forward. You only require steady ammo and a good way to measure muzzle velocity, so the powder is the sole variable. Better of luck for you!
Previously this 12 months, there was a PRS match in Nebraska wherever competition needed to shoot inside the snow, and many of the identical rivals will likely be found in Oklahoma capturing “The Heat-Stroke” match mid-July exactly where temperatures could exceed a hundred levels!
Some powders ‘cheat’ ,earning and immpresion of security with a particular flat line band. Vihtavouri N140 is 1 this sort of powder its lifeless stable in 18-23°C temperature selection ,which covers temps Considerably on the yr in central Europe .
I’ve been shocked before! I program to check my lots of powders myself and find out what I uncover. I possibly gained’t have time to do this until finally closer to hunting period, so you could possibly examination yours and see what you think.
Load after load, year just after time, trophy hunters and very long-range shooters need excellent uniformity and precision. The Enduron Technology powder With all the slowest melt away fee, IMR 7977™ yields exceptional efficiency during the .
I commenced at 58gr and worked around 60gr. Wasn't positive the flat dependent Partition would make additional pressure compared to Hornady bullet so I finished there.
Yeah, Rick it seems like we predict a great deal alike! I do shoot at temperatures which are diverse than I zeroed, Though I Verify my zero very usually … so I guess that limitations that to a degree. I primarily shoot at fifty five-95 levels 90% of enough time, but Once i’m looking that could be as low as ten degrees or at a summer season-time match, I would shoot in temps as high as one zero five.
The Enduron powders are mentioned to provide best load density, resulting in reduced SD numbers for strain and velocity, which ought to consequently, present excellent precision.
That may be just what we had been looking to do below, and I couldn’t concur a lot more. I do question how those newer powders would do, but I suppose I’m skeptical in Alliant’s good quality at this point. But, it’d be fascinating to see the data!
They suggest you put the Doppler beside the rifle, and it looks as if they might account for that offset since they interpret the final results and correct for it. The center from the imr 7977 in stock gadget will likely be less than twelve″ within the barrel, which isn’t A great deal if you’re referring to measurements taken 50-eighty yards down array.
That is a great position, Martin! I hadn’t considered that, but you’re Definitely right. There may be some price to the powder Possess a predictable, linear transform in muzzle velocity.
That’s why I never did a imr 7977 in stock write-up over it. Truly to reach any universal truth of the matter you’d want to check over many lots of Every single primer and I just don’t provide the time to do this. It’s be Yet another attention-grabbing experiment!
A number of from the powders include attributes imr enduron powders such as a chance to retain reliable velocities above a wide variation in temperatures, an additive that reduces buildup of copper fouling during the bore plus the elimination of dinitrotoluene like a deterrent coating and dibutyl phthalate as being a stabilizer. Alliant phone calls this chemical engineering EI technology, and IMR phone calls it Enduron Engineering.
It truly is not unusual for velocity spreads to narrow as bullet bodyweight boosts. Except for a few scenarios, 4955 manufactured the very best groups with the Browning rifle. If accuracy and velocity of all of the bullets analyzed are extra with each other, IMR-4955 was the throughout-the-board winner for that test rifle.
