I believe most Triumphs will shoot plenty good with 100-120 gnv Bh209 and all of the bullets mentioned. Personally I've gotten good results with 110 gnv BH with 250 Shockwaves, SST's, 275 BE Parkers, and my favorite 300gn .458 Remington HP's. I'm going to hunt with the Remington's. I did the final range tuneup a few days ago and they shot consistent 2" groups at 150yds with 110gnv BH and Black Crushed Rib sabots. The Parkers are right up there also. I could shoot any of those three with good confidence.
