I have tried the 55 grain Hammer Hunter in the 6mm ARC over A2200 with good results. I am looking to give a more temp stable powder a try in addition to the A2200. I expect IMR 4198 may work well though I'm not finding any data that quite supports IMR 4198 in this application. I do see data for VVN130 & H322 perhaps they would be a better choice for the application at hand.
Am I off base to think IMR 4198 may be a good fit as a propellant in the 6mm ARC for the 55 grain Hammer Hunter?
