3400 fps smoking.Not me, but Whoa! I'd bet they would be coming out like molten copper.
Hello Lcq,
From all that I can gather, you are doing right by using lighter versions of those types of bullets.
They are harder than old fashioned lead core/guilding metal jacketed bullets.
Also, they are typically sharp pointed, which means they have to radically change shape from their original profile to reach their ideal expanded profile.
The higher velocity possible with light weight projectiles is what monometal expanding bullets seem to need, in order to encourage their full expansion, especially if striking animals that do not offer much resistance (impala, bushbok, reedbok and many others).
I'm a grumpy old man who has successfully bagged a huge pile of animals in my life with various calibers and bullet configurations, resulting in my concluding the two following things:
1. I distrust hollow point bullets of any sort, rifle or handgun types.
2. In hunting rifles, my best results (that would be, one shot per animal consistently) out to about 300 yds has been with old fashioned Round Nose Soft Point ("RNSP) bullets, heavy for their respective calibers and fired at moderate velocities.
If I was for some reason wanting to switch to the TSX or TTSX type bullets, I am with you, Mekaniks and others here who use them on the light side/high velocity.
Cheers,
Velo Dog.
I thought about that but for less than 20 rounds max on a hunt it shouldn't really matterAt that speed I would think the barrel would copper foul pretty quickly.
I just hit this guy three times with a .225gr TTSX out of my .340:
The first shot went through both front quarters including some bone, ended up under the far hide, and looked like this:
the other two shots went through the bull at an angle and exited into the brush somewhere. All three were going about 3,050fps impact (3,160fps MV) and did a lot of damage on their way through, turning the tissue widely around the bullet path to liquid jelly. He only went 20yds before laying down for good.
Nice moose. A full day of work ahead to fix it up.
I've killed exactly one deer with the 308 130gr TTSX. Impact velocity of about 2,850 fps.
Broadside high lung shot. Deer dropped, kicked a couple times and expired. Lungs were jelly, as you might expect.
Not much of a test, I admit!
I just don't know how that TTSX managed to expand and dump all that energy to make such a mess, hitting nothing more than the soft rib of a doe.
The second video here: http://www.barnesbullets.com/information/high-speed-video/ explains it I think.
