I was doing a lot of hunting load development last year for my Tikka T3 Lite using 150 gr. bullets. I only did a little work with the 150 gr. Hot-Core before dropping it due to the spotty availability. I ended up using the Sierra 150 gr. Pro-Hunter Spitzer instead. Bagged the biggest whitetail doe I've ever seen with the Sierra and the performance was perfect. Here's are the three loads I developed for the three bullets. The Speer load was showing potential but I ran out of time. I'll probably try it again with IMR-3031 and Winchester brass (more capacity).

A three shot group with the Sierra at 100 yards. The Speer and Nosler Partition bullets were just as accurate. If I can find more Hot-Cor Bullets I'd love to try them with IMR-3031!
