Did the rifle operate properly at the 25 grain loading?At the 25 grain entry level, I had 2 failures to feed which I attributed to short stroking. As I went up the charge scale, the FTF's went away. The rain arrived just as I was ready to 'graph a few rounds from a test batch, and I didn't get a chance to test the N135 batch. I did, however, get to test the H 4598 compared to I 4598, and at the 25 grain level, I got the following results out of my 18" rifle:
I 4895: Average MV=2287; ES=47; SD= 19
H 4895: Average MV=2352; ES=62; SD=25
I found it interesting that I 4895 was not called out as a viable powder by Hornady, but H 4895 was recommended in all but the lightest bullets. And, the estimated MV for 25.2 grains (max load) of H 4895 was 2400fps, and I averaged 2352fps with 25.0.
At the same time I'm working with this new ARC that I built, I've got a new 300 HAM'R that I'm working up loads for! This may be too much fun for me to handle!!
