[#1042]

I Cody was gifted a box of Spoor 140 gr bullets for his 7 mm. I am calling them half mono 🤣 because of the design/ construction. In the  7 mm 2800 fps is achievable, and I have no doubt of the effectiveness of these bullets at that velocity.

I have two questions though. 
I have downloaded some to 2350 fps to try reduce meat damage at 100m or less type shots (80 % of all shots on the Impala)

I have also loaded some to 2555 fps for regular hunting. 
Do you guys think there is any problem foreseeable with the 2350 fps load on game.
Do you think there will be  a clear notable difference between the 2350 and 2550 fps bullet performance?

Therefore I am me.

It might still give damage, though I don't know how much. I have had meat damage with 180gr Sierra Pro-Hunters @ 2400fps.

 

We spoke along these lines in several discussions - hitting bone almost always causes bloody meat.

Seeing as Rudy is a bit reluctant to release BC details of his bullets, it makes it a bit difficult to calculate at what range the speed drops below the 2000 fps that he specified for proper expansion.

Using a thumb-suck 1 fps reduction per foot travelled, the bullet with a MV of 2350 fps should drop below 2000 fps at around 110m.

The Pro-Hunters still expanded at 350m. Their speed was somewhere around 1650fps.

Going to try get a test shot done this week end.
