Such as it is usually said which the 6XC is a lot better than the 243Win because it can reach the exact velocities with 7 grains significantly less powder. Now this is legitimate but IMO I believe The main reason it is best is since the powder burn rate of the powder being used is better for that cartridge capacity. I am certain Hodgdon could establish a powder exclusively for that 243Win that might enable it to be accomplish better still in comparison to the 6XC simply because loaded to a similar pressures the 243Win will burn much more powder and as a consequence have the next velocity. The trick is getting The best powder for that cartridge potential, barrel length and bullet.

I just hope a lot more transparency will come out before long to swatch rumors and speculation. I despatched them an e-mail asking for clarification. I'll write-up right here what I hear again, if It is really something a lot more than a generic response.

Some brass is sorted by headstamp and/or primer pocket dimensions. This will be Plainly said in the solution description.

I did not get single digit SD’s with equally IMR powders, Nonetheless they were being even now respectable. I’m confident I could great tune the masses for almost any of those powders and reach amazing outcomes.

Personally, I normally want at the very least 10 photographs about a chronograph just before I put any excess weight around the stats (like normal, SD, ES) being consultant for IMR 7977 that wide range of ammo. I’ve observed men shoot 5 shot strings, but to me that isn’t more than enough. I’ve just observed as well large of the variance among exactly what the stats say following 5 photographs and whatever they sooner or later say following A further 5 photographs.

That’s exactly what I’ve read. There may be Yet another Australian powder you’re discussing, but that just sparked my memory.

But, H4350 had additional variance over the low stop (20 to 65).

There are generally a few outliers that ignore the “rules of thumb” that we may very well be employing.
