The majority of these powders labored very well with a range of 7mm bullet weights, although 1 was limited to just one fat bullet.

didnt use much with the enduron powders but normal dynamics also created the alliant 2000MR and 4000MR powders which have been absent for awhile.

They eliminate self confidence inside their dope, concern their rifle or scope, and usually just spiral into annoyance. But, quite a few by no means make the relationship that it may be a weak powder choice that prompted their trajectory to vary so dramatically.

They haven't taken them off their Internet site and possess no mention of them staying discontinued on internet site? In which you hear this? I googled it and only detail that comes up Is that this publish?

However, within an engineering sense the concern is whether or not the design/law is really a ok approximation. Is it in good shape-for-function? Does it crank out predictions which can be adequately precise. For instance, the total 6 DOF system of equations with the motion of the rotating, symmetrical ballistic projectile is a much better approximation than the three DOF program of equations however the three DOF system is sufficiently precise For lots of trajectory calculations. A fascinating level Because the bullet would have a greater diameter at better temperature due to thermal growth. But, as usually, the critical dilemma may be the magnitude from the outcome, Would it not alter the muzzle velocity by 100 fps, ten fps, one fps, 0.

I am aware copper bullets are for a longer period but dang I would've needed a fall tube to make it do the job to obtain to even near max load. Photographs confirmed significant force early on in a very rifle that usually likes the edge of max.

Wow, Blaine. I could absolutely see a transform of charge concerning tons, nevertheless the muzzle velocity going down as temperatures go up is one area I haven’t noticed. The reasoning is bending imr 7977 in stock my head a little bit. Could you notify me somewhat more concerning the particulars of any time you saw that?

You do realize that any time you change the temperature of your bullet by that Excessive of the mount the physical sizing on the bullet truly alterations. It’s No surprise the velocities ended up distinct If your diameter with the bullet is .003″ distinct at those two temperatures. To even get considerably accurate final results of the theory the particular rifle would need to be heated and cooled at the same time as being the bullets.

I might say the temperature of my rifle and ammo are almost always exactly the same, Until the rifle has heated up on a lengthy string of fireplace (i.e. chamber is one hundred forty levels and also the ammo is ambient temperature). I'd personally concur that it looks as if that will be the commonest circumstance.

Attention-grabbing details … but I’m acquiring velocities of 2840 fps with one hundred thirty Hybrids applying H4350 imr enduron powders in my 22″ 6.five Creedmoor. There are Unquestionably no indications of pressure. I’m not the person who pushes to have eek out that final little bit of muzzle velocity using a “hot” load. That appears to not align with the theory, but there are so many components that Participate in into it (which includes the individual imr 7977 in stock barrel features) that it’d be difficult to attract conclusions from compact sample sizes.

I did see my BC strengthen somewhat by pointing. So in the event you’re searching for each very last gain you may get, pointing can be value your time and efforts! But I didn’t do that in these checks. I seated the Berger 140gr Hybrid bullets utilizing a Whidden Gunworks Bullet Seating Die, that have proven to offer very regular and repeatable seating depth.

The target of the test was to quantify the temperature balance from the 4 powders we’re serious about. To do this we’re gonna evaluate the muzzle velocities of load ammo for a wide array of temperatures. Allow me to promptly run from the set up of how the check was carried out.

The solution is easy, the IMR Enduron powders feature a built in copper fouling eliminator, are insensitive to temperature extremes and therefore are made up of little sized grains for simple metering and exact loading density.

Interesting. I assume I haven’t heard of that. Thanks for sharing. It’s in all probability a fairly comprehensive-featured engine if it has a place to account for this.
