Wound’t magnetospeed readings be frequently a little bit highter, as it actions the relative speed among exiting bullet and recoiling rifle, and not the relative pace among bullet and “earth”?

I don’t think I recorded any temperatures higher than about 180 levels F. Is that this documented in any peer-reviewed spot you are able to point to? You’re a pointy man, but I usually try to offer third party assist in my posts (like in this one particular I referenced Litz along with the investigation on Kestrel’s Web site). Exactly where can I browse more details on the barrel’s position In this particular?

Speer Bullets, Federal Top quality and CCI. The catalog states: “The powder charge weights mentioned within our information tables are most. For rifle and pistol masses, the maximum powder rates needs to be diminished by 10 p.c to determine a least or setting up powder charge.”

The good news is really a taking pictures buddy has a whole new LabRadar And that i personal a MagnetoSpeed and we're going to discover for ourselves this weekend. Once more thank-you the perform that you choose to do.

In addition they are formulated for being temperature insensitive, much like what we’ve found with Hodgdon’s Severe number of powders.

Give thought to for those who applied a powder which was specially formulated for being temperature secure like IMR 4350, one of the Reloader powders, or even the many other kinds. You’d may very well be off by double that! Thanks for inquiring the problem, mainly because it definitely drives The purpose dwelling.

A fast Be aware over a comment you manufactured about H4350 and Varget. The rifle used experienced a 22″ barrel and this is why the velocities IMR 7977 with Varget had been bigger than that with H4350. Varget has the best burn off fee for that barrel size. H4350 is better with 24-26″ barrel lengths mainly because it is a bit slower and is in turn a far better powder to the for a longer period barrel.

I do think the tutorial response can be a sample measurement of 30+ is required to have significant self esteem the sample is consultant of the inhabitants. But not many fellas do this, mainly because There's a diminishing stage of returns.

I'd personally say the temperature of my rifle and ammo are almost always the same, Until the rifle has heated up on a protracted string of hearth (i.e. chamber is 140 levels as well as ammo is ambient temperature). I might concur that it looks like that might be the most typical scenario.

The ammo was meticulously handloaded with what we believe to be the best machines obtainable. Each and every excellent load starts with superior brass. The provision of excellent brass has long been these types of an issue that many shooters choose which caliber of rifle to make based mostly upon whatever they can find great brass for. Lapua is often acknowledged as the gold conventional On the subject of brass high quality, and permanently purpose. Lapua brass may be very constant and tends to very last for a longer period than other models.

Attention-grabbing concept while! May be suitable. I’m satisfied with the outcomes I’m acquiring, so I assume whether all the powder is burned or not isn’t something I’m everything worried about.

Perfectly, Mike. It’s IMR 7977 in all probability not as huge of the deal as you're thinking that. Think about the velocity distinctions in the chart I posted from the feedback. That person chopped a barrel down a single inch at any given time, and recorded muzzle velocities. Recognize that a 22″ barrel was just fourteen fps slower than a 27″ barrel.

The answer is straightforward, the IMR Enduron powders feature a inbuilt copper fouling eliminator, are insensitive to temperature extremes and so are made up of tiny sized grains for easy metering and precise loading density.

Thank you, Sir. Adhering to the direct of those people who IMR 7977 are more knowledgeable than me has paid out off. I take advantage of H4350 completely and I would like all the help I may get.
