My best load for 100 grain has been I4831.. H is a bit slower I believe. I use 22 with heavier bullets.. But it is accurate with 100 gr. Never shot many Speer in that caliber.. I think you will like the .25 it is a deadly coyote rifle for normal hunting.. On windy days, it is my choice, just killed one this am with a 75 gr. Horn Vmax.. Never used Varget in this caliber..
