195gr TMK performance and minimum expansion threshold

I picked up some factory ammo very cheap in 300 wsm loaded with 195 TMKs. The ammo shoots about 0.3 MOA and clocks at 2840 fps and the ES is low enough for my purposes.

Considering using it to go after elk and black bear this fall. Black bear probably won't be much over 300-400 lbs. The rifle shoots boring old 180gr accubonds very accurately so that's load I've mostly used in it to kill stuff. Just as likely to get a shot at 50 yards as I am at extended ranges. For me extended ranges mean 600 yards, 700 in perfect conditions. I'll shoot rocks and steel at 1500 but with game I just don't trust my wind calling enough to go anything close to that. It is extremely rare that I'll get to use my kestrel in a hunting situation.

Wondering if anyone has shot animals in the 300KG weight class at both close and extended ranges with this bullet?

Hi Philipp, this is a good bullet. Regarding your needs, I have set up several clients with this bullet for the same hunting situations out through Wyoming and Montana etc. No complaints. Go ahead and use it.

Re: 195gr TMK performance and minimum expansion threshold
This thread is of particular interest to me.

On my to do list of projects is building a 195TMK load for my 308, specifically intended for longer range cross gully shots at sambar.

Previous work with the 175TMK in this rifle gives me hope that I will see 2500, maybe 2550fps from the 195 which should keep impact velocity above the 1800 fps wall out to at least 500, hopefully 600 yards - more than far enough for my purposes.

I will try to dual load this with a closer range load using the 165 Swift Scirocco, my hope being that the similarly shaped, although lighter, Scirocco will have a similar point of impact to the 195 TMK at shorter ranges from my .680 @24" barrell.

My concern is that if the soft TMK encounters the humerus on a 200kg plus animal that it MAY not have enough steam or integrity left after breaking the humerus to penetrate the chest cavity.

BTW, I could go down this path with my 30.06 but for a range of reasons, this 308 is better suited to longer range range shots than my .06, despite giving up maybe 100 yds to the .06
