Ok I just got back from the range where I tested A4350 vs H4350 vs IMR4350.
I was shooting my Tikka T3X Superlite in 6.5 CM. I was using once fired Sig brass , Fed 210 Match primers, and 130 gr ELD-X bullets at .020” off the lands. I used 42 gr. of powder for each of the 4350’s and here is what I got. Temp 36F OVC skies and winds 07005KT.
5 shots of each
A4350 Avg. velocity 2474 fps, SD 18, ES 41. 5 shot group measures 1.590”
H4350 Avg. velocity 2675 fps, SD 18, ES 44. 5 shot group .906”
IMR4350 Avg. velocity 2669 fps, SD 17, ES 40. Shot group 1.294”
Granted, this is just one example, but I have averaged 150 fps below book on just about every cartridge I have used it for. I got excellent accuracy results with it in my .338 WM using 210 gr TTSX’s, but again 150 fps avg slower than what was in the manual. I k is every gun is a different story, but I’m done with A4350 and will move to either H4350 or IMR4350 in my .338 as I did not try those powders last year working up the load as I was trying to save what little of H4350 and IMR4350 I had at the time.
