And the rabbit hole begins. Welcome to the wonderful world of Handloading. Where each of your rifles can be squeezed to get a 1/4 inch better accuracy for just $400 each in components.;)
I have used all four combos you are looking at. Every rifle will have it's favorite. My 270 really liked IMR 4831 and shot both the 140 Accubond and 150 grain Partition very well. My Tikka in 308 win, shoots several bullet in the 165 and 150 well using IMR 4064. YMMV
Well it looks like Howard truly did have a Marvelous Team and was too much for Purdy and the rest of my team. Congrats to Howard, and thank you @Duck-Slayer for running the league again this year. Lots of fun.
Seeth had Brock Purdy. Not sure who had Caleb. I had Purdy in the other HT league and he carried me to the finals, but Howard was too much for me this week.
Learning some key lessons in patience and the rewards that can be attained by sticking with it are invaluable. Congratulations to your son. Enjoy the good eats that came with his success.
One deer was shot inside 50 yards. Double lung pass thru. The bullet appeared to have doubled in size with a larger exit wound. Deer got back up, ran thirty yards or so and tipped over. Most of the others were shot between one hundred to two hundred yards out. None required a difficult tracking...
