buffybr - "I think just about any .375" cup and core bullet would easily kill a deer. Why waste a 300 gr TSX on small animals at reduced velocities."
I agree with your statement about killing deer. I also agree with the other helpful posters who pointed out that lighter bullets will work just fine on deer.
My 'armchair African and Alaskan hunter' mind was thinking that 300 grain bullets at 2450 to 2550 feet per second was fast enough for about anything. Also, I model a jacketed bullet trajectory in my head of +1" at 50, +2.5" at 100, +2" at 150, zero at 200, -6" at 250, -12" at 300, -24" at 350, -36" at 400, and -48" at 450 yards. This is my game rifle reference trajectory. No rifle I own actually shoots this exact trajectory, but all come close (with the bullet and velocity combination that I reload).
Thinking this way has helped my game shooting over the years.
The 375s that I own were bought with the thought of using heavier bullets for Africa or Alaska, yet lighter ones for the lower 48 in the US. Sadly, I no longer get to the range often enough to keep my shooting skills as sharp as I would like. Nor do I have enough time to stay on top of a bunch of reloading. So, I decided to reduce my 375 loads to just three bullets - potentially a Barnes solid, the 300 Accubond, and the 300 TSX. These bullets all group close together in my 375 Rugers.
With these thoughts in mind, I started this thread to see if anyone had experience with the 300 Accubond or 300 TSX on light animals such as deer. I wanted to find out if hunters were getting at least some minimal expansion on deer. If so, I planned to settle on the Accubond and TSX. Then anytime I was able to get to the range, I would be practicing with actual loads and my rifles would be sighted in.
