Shootersworld 4350

[Evlshnngns]

The bottle states 6.5CM: 41.5gr with a 140smk= 2650fps, nearly 62k psi. No listed barrel length for the velocity. I loaded up some rounds with Barnes MB140's for my 12fv. Ill report what hits the paper.

If you have a favorite load for this powder (any cartridge), post it here.

Sounds similar to H4350. I think I started at 40.0 grains when I ladder tested my 6.5 Creedmoor using H4350. I have not shot it since. Hornady 140 ELD Match were used. 41.5 gr of H4350 was the exact charge I used that was pretty much the best group I had with my Shilen Creedmoor barrel. (I did have one pesky flier that kept it from being a one hole group.) I did not chrono it. 40.5 gr was perhaps my best group since no flier, but all groups could be covered with a dime at 123 yards.

Would like to hear your results with that powder.

I had 10 primed brass left and 10 straggler PPU 6.5MM 120'S. loaded a pressure test, five loads, two shots per. In the dark for load data, some of these might get pulled. I really need to buy a chrony instead of new powders.

This powder should work in my fast twist 22-250 and 243.

I'm currently loading IMR4350/41 grains under a Hornady 140 grain BTHP in Hornady brass and BR-2 primers. Velocity is 2655 fps and my last range trip put 15 into 3.77 inches at 425 yards. Temp was 37 degrees, humidity 80% and a 6 mph cross wind. The same load in warmer weather averaged 2688 fps.

Not bad shooting, GaCop.:first:

I ended up with two .5" groups (three shots each) out of the four loads with the 140s. Those are good odds with this gun, hopefully I can find a combo to do it consistently.


The 120's shot all over the place and hit pressure at 43gr. Maybe I had them at a poor seating depth.
