You will find statements built once in a while about cartridge patterns becoming extra efficient than others. For instance it is usually stated the 6XC is much better than the 243Win because it can get to the similar velocities with seven grains considerably less powder. Now This is often genuine but IMO I feel The main reason it is better is because the powder burn level of your powder being used is healthier for that cartridge capability. I am confident Hodgdon could develop a powder solely to the 243Win that will allow it to be carry out better yet as opposed to 6XC mainly because loaded to precisely the same pressures the 243Win will burn extra powder and as a consequence have an increased velocity. The trick is discovering The best powder for that cartridge capability, barrel length and bullet.
The MagnetoSpeed unquestionably wasn’t lagging much powering the LabRadar. Like I reported, it absolutely was generally within a pair fps.

I begun at 58gr and worked approximately 60gr. Was not positive the flat centered Partition would create far more force in comparison to the Hornady bullet so I finished there.
Wow, Blaine. I could undoubtedly see a modify of price involving heaps, but the muzzle velocity going down as temperatures go up is a thing I haven’t witnessed. The reasoning is bending my intellect a bit. Could you tell me a little more imr 7977 in stock regarding the particulars of any time you observed that?
I did not get one digit SD’s with equally IMR powders, but they were being nonetheless respectable. I’m guaranteed I could wonderful tune the masses for any of such powders and attain wonderful benefits.
It absolutely was also an incredibly windy day and I was rushing pictures in between gusts of wind. I am shooting the a hundred and fifty five grain Terminal ascent with 72.5 grains of IMR 8133 out of ADG brass. I Individually such as powder and have experienced great luck to this point.

Sorry for not studying your write-up extra meticulously. Your opinions, because the Brits would say, are location on. For my very own knowledge sets I make a histogram Together with calculating the indicate and SD. Histograms enhance mistake bars.

In addition you’ll get to satisfy A few other people who find themselves into this stuff, and maybe even create a handful of IMR 7977 friends which can help you alongside.
It can be common for velocity spreads to narrow as bullet weight raises. Aside from two or three occasions, 4955 developed the ideal groups in the Browning rifle.
