Let's see 39mm to 43mm is a 10% increase in capacity. Using LRRPF52's data using 123 AMAX and CFE223 in a 14.5" barrel, http://www.65grendel.com/forum/showthrea...ot-Grendel
31.1gr 2489 fps
31.4gr 2520 fps
31.7gr 2532 fps
32.0gr 2553 fps
32.3gr 2572 fps
32.6gr 2598 fps
32.9gr 2612 fps
Increasing 31.1 gr by 10% is 34.2gr and increasing 32.9gr by 10% is 36.2gr. Interpolating from the known data, 34.2gr would result in 2700fps and 2828fps. Now these calculations are elementary at best, but I think we could expect a MV in that range. If we were to see the military develop a canister powder I think we might see a MV in the 2800fps.
What say y'all am I completely off.
On a side note, I'd like to see how H4350 worked in that case.
NOTE: Interpolating outside the boundaries of known data will skew the results to some degree.
