I don't have much to add, but will confirm what others have reported. My first 17 Rem. was in 1971 and began a love affair that is still on going. I never had one that was a fouler and the go to powder in those days was 4320 as others have posted, along with W760. Those powders still work great in the 17 Rem. with W760 being exceptional behind a 30gr. bullet. In an 18" barrel Model 7 I owned, H322 worked the best of any powder I tried. That powder had good accuracy in my longer barrel 17's, but not any better than 4320. IMR8208 is what I mainly use now in all of my 17's and 204's. But, in my 30gr. loads in the 17 Rem. I still use H414/W760. All of my loads are with Rem. 7 1/2 primers.
