And I concur with the point on Varget getting far more stable at decreased temperatures. Another reader manufactured a remark about that, and Truthfully I hadn’t designed Observe of that before you decide to guys explained a thing over it. It's an interesting issue, as well as a persuasive scenario for hunters to produce masses according to Varget. I Individually hunt using a 7mm Rem Mag (aka God’s hunting cartridge ), so I ponder if H1000 or Retumbo exhibit comparable Houses.

This really is why just investigating the magnitude of the difference should be taken that has a large grain of salt Unless of course the stats are there to support the summary that they're unique and conventional mistake bars describes it far better than my extensive winded description.

As I realize it, H4350 and Varget are actually made by an Australian company. They are really marketed underneath a unique identify there (I do think AR2209 and AR2208), but I’m not sure should they’re a hundred% equivalent.

Honestly, we just aren’t considering that powder as a result of what we’ve seasoned with it when it comes to temperature sensitivity.

Thanks, R700. Sounds like pretty much as good of a proof as I’ve read. Undoubtedly fits my encounter. On a side note, I do use H4350 in my 22″ six.five Creedmoor and I really like the outcome I’m having. But I don’t doubt that I'd have the ability to squeeze somewhat more muzzle velocity from another powder. I understand lots of men chase that past minimal little bit of muzzle velocity, but All those 25 or 50 fps bumps have nearly no effect on hit probability In relation to extended variety targets.

ninety four% of shooters ending in the top a hundred inside the Precision Rifle Series (PRS) prefer to run one of gun powders through the Hodgdon’s Extreme Number of powders, like H4350 and Varget (see the information). Though those powders may not usually create the quickest muzzle velocities, veteran shooters have discovered to believe in that Intense powders will supply steady muzzle velocities throughout virtually any surroundings.

(two) Assuming RocketmanOU is accurate, it can be Frightening to Imagine the sample normal deviation suggests absolutely nothing with regard to the regular deviation from the populace even assuming the chance density purpose in the population is known.( Even so your observations about SD for ten and fifty shot groups delivers comfort and ease.)

The opposite issue is a question: Was the two fps reading through difference With all the Magnetospeed regularly increased with the Labradar? 5-6 many years back, a retired radar engineer who had made a Doppler device for his personalized use shared some output from it with me that he’d produced capturing a forty S&W pistol. Its output was a continual velocity vs. time plot as opposed to velocity vs. distance. It showed one thing Harold Vaughn experienced shown which has a magnetometer rig in his guide, Rifle Accuracy Facts, about 15 yrs ahead of him, and that is that in excess of the first number of calibers of bullet journey past the muzzle, muzzle blast even more accelerates the bullet a little.

That’s since the “Hodgdon’s Serious powders accomplish equally as nicely at one hundred twenty five° because they do at 0°. Utilizing an special extrusion method and exacting high-quality benchmarks, Hodgdon has made a line of propellants that performs much better at hot and cold temperatures than some other powder out there.”

Thanks to the reference. Essential reading. A paradigm changer. I might have additional two a lot more conclusions and restate a person summary”

In performing experiments fantastic tools is very important get more info but equally very good methodology. I can understand why precision rifle Level of competition shooters wouldn't want to describe their handloading methodology in great depth so as not to give away “trade secrets” and therefore reduce a competitive gain. But I am discussing the methodology to determine the 100yd precision, 100yd precision, the imply muzzle velocity as well as the SD in the muzzle velocity. With radar, developing the imply muzzle velocity and SD with the muzzle velocity seems very simple.

Yeah, Rick it looks like we predict a great deal alike! I do shoot at temperatures which can be distinctive than I zeroed, Even though I Test my zero pretty regularly … so I suppose that limitations that to a degree. I generally shoot at 55-95 levels 90% of the time, but when I’m looking that may be as low as 10 levels or in a summer time-time match, I'd shoot in temps as higher as a hundred and five.

The MagnetoSpeed surely wasn’t lagging much powering the LabRadar. Like I said, it absolutely was constantly within a few fps. Honestly, there wasn’t a transparent way in my test to be aware of which a single was right … so it’s to some degree blind faith that makes me believe that the LabRadar was the one which was closer to suitable. But I've talked towards the male who invented the LabRadar, and know a little regarding the technologies powering it … and it seems very solid. He really advised me its No less than correct to 0.one%, but The truth is its likely a lot better than that. I can’t validate nor deny that, but it really just provides me a reasonably large perception degree from the product. A superb take a look at may very well be to own 2 of them side-by-facet, and I tried that at some point … but couldn’t get them both to examine concurrently.
