Effectively, I have guilty Patrick for conducting this exam. He was the just one who came up Along with the notion and went out and collected the data. I do think he did an excellent career.

Measuring specific results absolutely is intellectually fascinating. Realizing unique effect may have a functional price in that more likely to know diploma of applicability to other rifle-ammo-sight-System devices.

I don’t Feel remaining off by one-two levels would have any measurable impact on hit chance, nonetheless it’s a lot more on the twenty five+ diploma modifications that will bring about a skip. The lesson Here's to only not believe the muzzle velocity you shot 60 degrees might be similar for 90 degrees. It just doesn’t work this way. But unfortunately, a lot of people don’t know that and many ballistic calculators don’t allow you to account for this sort of variable.

They have not taken them off their Web-site and have no point out of these getting discontinued on internet site? In which you listen to this? I googled it and only thing that will come up is this publish?

Quite interesting. I’m not a benchrest man, so it’s great to determine what All those fellas are accomplishing. That seems to in good shape what I’ve heard, much too. It’s an interesting tiny sport! You'll find almost certainly loads of classes we could master from that aspect with the precision rifle globe.

I have a number of factors entered in my Kestrel, and that seems to have actually served put me in the center of a goal on the main spherical. It’s been shocking how accurate it really is just after I started putting in These muzzle velocities by temperature instead of just one common muzzle velocity. I don’t come across myself needing to go tweak it all the time to make it align imr 7977 in stock with hits in the sector.

Vaughn. I guess you can learn a whole lot from the person like that. That is definitely an interesting concept with regards to the submit-muzzle acceleration, but it really looks like These guys might have corrected for that from the software program. Up coming time I see them, I’ll unquestionably inquire! You’ve got me pondering!

It’s funny how an issue like which can provide to light several of the standard assumptions we make! I’ve definitely considered that just one quite a bit because I 1st read him advise it.

I'd personally say the temperature of my rifle and imr 7977 in stock ammo are almost always exactly the same, unless the rifle has heated up on a long string of hearth (i.e. chamber is one hundred forty degrees as well as the ammo is ambient temperature). I might agree that it seems like that may be the most typical state of affairs.

Bear in imr enduron powders mind these had been all for the 22” barrel on our check rifle, plus your mileage may well change. We also just picked Risk-free masses for each powder, and didn’t do load advancement to view what velocities for every powder could be at max pressures.

Initial thank you for your time and energy and skills in performing the experiment and Next in answering my issue.

Sorry for not examining your write-up extra very carefully. Your responses, since the Brits would say, are place on. For my own information sets I produce a histogram Along with calculating the mean and SD. Histograms enhance mistake bars. We're all thankful to Cal and his colleagues for some time, exertion and income to expend in doing mindful experimentation.

it is sweet to have unbiased simple fact centered details to critique. I'm able to’t wait to read your barrel analysis. My son incorporates a 300WM within the back burner until we examine the barrel comparison in BL’s ebook. Was likely to do a PR barrel but will wait around till we see the final results.

Good function Cal. Could you notify me in the event you experienced 100% powder burn up during the 22″ barrel? Also was the speed based upon the Lab radar and confirmed with Magnedo, or common of both equally.
