That’s excellent, William. I hope this Web site conjures up Other individuals to do identical checks. The setup was fairly straight-forward. You merely want consistent ammo and a good way to evaluate muzzle velocity, so that the powder is the only variable. Best of luck to you personally!
Reloder 33’s burn off rate is a little bit too sluggish for general use within the 7mm Remington Magnum, but it really fired Speer a hundred seventy five-grain Grand Slam bullets more rapidly than other powders and gave the smallest group.
The theory below was to isolate the powder as the variable, not the entire weapon procedure and optics. This experiment did that rather nicely.
IMR Enduron 7977 is among the slower melt away charge propellants during the Enduron family. Loading density is great for magnums, contributing to superb uniformity. This is the correct magnum propellant yielding remarkable functionality in 300 Winchester Magnum, 7mm Remington Magnum and 338 Lapua, amongst other cartridges.
Loading density is great for magnums, nicely filling the case at utmost prices, contributing to wonderful uniformity and accuracy. The 7mm Remington Magnum “never experienced it so excellent”!
I started off at 58gr and labored around 60gr. Wasn't certain the flat dependent Partition would produce extra stress as opposed to Hornady bullet so I finished there.
Hodgdon has adjusted suppliers and destinations on many in their labeled powders through the years, based upon specific prior factories not being able to provide it any more.
The most crucial features from the Enduron series are copper fouling eliminator, insensitivity to temperature changes, great loading density and staying eco-friendly.
Exciting Exam. One thing I observed is always that even though IMR4166 didn’t experienced the smallest muzzle velocity for every diploma fahrenheit variance, It appears to have quite possibly the most liniar attributes.
The ammo was meticulously handloaded with what we believe that to become the ideal products out there. Just about every great load begins with very good brass. The provision of excellent brass has actually been these kinds of a concern a large number of shooters pick out which caliber of rifle to make dependent on the things they can find very good brass for. Lapua is often acknowledged because the gold normal In regards to brass excellent, and permanently explanation. Lapua brass is incredibly reliable and has a tendency to very last extended than other makes.
1 fps or 0.01 fps? Would it not change the team precision at a hundred yards at all? Would it not change the SD in the muzzle velocity whatsoever? Visit the array that has a presented rifle, ammunition, sighting technique and platform and determine the team precision at one hundred yards, suggest muzzle velocity and muzzle velocity SD for the presented ambient temperature. Then all specific results like outcome of temperature on powder and any IMR 7977 effect as a consequence of thermal growth or transform in Bodily properties are “bundled” within your measurements. This is the common engineering method but degree pf applicability of success to other rifle-ammo-sight-platform units is probably very little identified at greatest.

Quite a few completed shooters place a large emphasis on using a temperature secure powder, but could we as shooters have forgotten the value of a temperature steady primer
You didn’t include the ailment of your rifle all through these IMR 7977 checks. Even though the powder could possibly be at a certain temperature because it’s placed into the feed ramp, it’s pretty difficult to predict just what the temperature with the load might be for the duration IMR 7977 of the moment of firing – esp. if it’s been sitting down during the chamber for quite a lot of seconds – brass will perform hottest heat rapidly.
