That’s excellent, William. I hope this Internet site conjures up others to carry out very similar tests. The setup was quite straight-forward. You only will need consistent ammo and a great way to evaluate muzzle velocity, so which the powder is the only real variable. Better of luck to you!
IMR 7828 SSC can be a magnum rifle powder with exactly the same melt away charge as normal IMR 7828 and takes advantage of the same knowledge. Nevertheless, because of the super brief kernels, metering is pretty much nearly as good to be a spherical powder.
Great post Cal. I tried A number of powders in my 6.5 Creedmoor and found H4350 for being quite possibly the most regular. I reside in Phoenix the place the inside of my truck can easily strike one hundred forty F. I’m happy to discover which they deviation is so minimal.
When IMR released their new line of Enduron Technology powders we understood we had to check all 3. With the entire powders on the market, you can legitimately inquire, why make new kinds?
(two) Assuming RocketmanOU is correct, it is Frightening to Believe the sample typical deviation claims nothing in regards to the regular deviation with the populace even assuming the likelihood density operate with the inhabitants is thought.( Nonetheless your observations about SD for ten and 50 shot groups brings convenience.)
I have multiple points entered in my Kestrel, Which appears to have truly helped set me in the center of the goal on the primary round. It’s been stunning how precise it is after I begun Placing in People muzzle velocities by temperature instead of only one universal muzzle velocity. I don’t obtain myself needing to go tweak it constantly to make it align with hits in the sector.
Hodgdon has improved companies and locations IMR 7977 on a lot of of their labeled powders over the years, based upon certain prior factories not being able to deliver it any longer.
A alter in temperature can influence the trajectory or ‘flight path’ on the bullet in two perfectly-identified methods:
At IMR 7977 least with the powders analyzed the variation in the muzzle velocity SD with temperature was only a few fps. Thus not variable for some, if not all purposes. Normally superior to turn a possible variable into a continuing. Wholly fully grasp your methodology did not allow shooting for precision.
If I fired 30 shots each and every time I checked my zero, my barrel wouldn’t previous incredibly lengthy! But I believe should you requested a statistician, they may be the kind of “purist” remedy you’d listen to. I had a knowledge scientist who worked for me (experienced a masters in Economics), and that’s what he mentioned.
That is an excellent issue, Martin! I hadn’t considered that, but you’re Completely ideal. There's some worth to some powder Have a very predictable, linear transform in muzzle velocity.
The primary functions in the Enduron collection are copper fouling eliminator, insensitivity to temperature changes, ideal loading density and becoming environmentally friendly.
Here is a great paper published by an OU professor on “The Myth from the 3 Shot Group”. I study it a few years back, and I bet you’ll love it!
Another fantastic examination on a subject that each one of us happen to be serious about – keep up The nice imr enduron powders perform Cal!
