James,
I can't comment on the exact bullet/caliber that you're asking about because i've never used that caliber but i can comment on the hot-cor bullets. I load the 120gr Spitzerin my 25.06 andi've also used the 150gr in my 30.06. I've found them to be very accurate and they did an excellent job on the deer i've shot with them. I don't think you would be disappointed with the speer hot-cor, they are good bullets.

Just a side note on the sierra pro hunters.I just recentlyworked up a load for a good friend with the 100gr pro hunters and his 243. The rifle is a Rem Mod 7 and only has a 18" barrelbut it's very accurate with these bullets. He's killed three deer in the last two weeks with that bullet with the closest being 150yds and the other two at about 200yds.He made good shots and they all fell right there, no tracking needed.I was very impressed at the internal damage those bullets did as the inside of the deers vitals were mush.
