Always shot the 260 accubonds but thought they opened up too much this past fall so I did some load development with the 270 gain Barnes TSX's and all I can say is WOW!!!! These are the most accurate shooting bullets I have put through the old H&H.
My final load I settled on was 76.5 of RL 15 pushing the bullet to an average of 2812 FPS. I shot 3 different 5 shot groups in less than 3/4" at 100 yards. 3 shots all stayed in an 1" at 200. Plenty good for HOT 375 H&H LOADS!!!(Good for ANY 375 LOADS!!)
Lastly I took 3 milk jugs and placed them at 300, 325, and 350 (my limit shooting distance with the .375) and went 3 for 3. The 350 shot, I held approx.4-6" over the jug and it struck almost in the middle.
Talk about a great new load...can't wait till April 15th and to see if we can try this new load out on an Idaho Spring Blackie.
