I'm wondering if the Barnes 180 TTSX or 200 TSX would be a good option. Anyone know what the velocity threshold is on them? Reason I'm asking is I prefer solid copper bullets for hunting.

Monolithic bullets are quite a bit longer weight for weight than jacketed lead.  Given the restrictions of the magazine on loaded length, the longer bullet will eat into the powder space available.  That will adversely affect velocity.

I believe I read that Barnes bullets need a minimum of 1800 fps to open properly, you might check their website for more information.

Kind of figured they would eat up some powder space, just curious if they would still be a decent choice for the cartridge.

From what I have gathered on other bullets, 1800fps is pretty typical. However, there are quite a few that they make that have lower velocities.

I have taken 5 deer with my .358 winchester 180 grain ttsx and also TSX, in Ca, the velocity at impact on 2 of the deer was about 1,400 fps and both bullets opened up just fine, one left a huge exit hole and the other was stuck in a broken rib on the off hand side, the rib was in multiple pieces and the bullet did open and decimate the lungs and heart.     Initial load was a 180 TTSX at 2,500 fps.
My Yeti gets the same velocity, I take TTSX melt the blue tips out of them to shorten the bullets to .975" and use a load of 37.3 Grains Hogden CFE to produce 2,500 fps same as my .358 winchester OAL is 2.210 and fit 6 in a 10 round 6.5 C magazine with no modifications. the TSX 180's bullets are too long.   I also shoot lehigh, 140 grain solid penetrators at 2,650 fps.   I use a metal plate with holes in it on my bbQ grill to melt out the tips, I let them drip into a pie pan, you have a little residue to remove after melting right at the tip of the bullet but it's easy to remove.   I find it amazing that after shortening the case and utilizing a different powder I can get the same velocity as my .358 and use it for deer and bears................Awesome is the Word.  I have taken 40 plus deer in Ca over the last 50 years with every caliber you can think of and by far the .358 has been one of my favorites.

Move Slow, Stop Often, Shoot quickly, Enjoy the journey

That's interesting. I wonder how much it changes the b.c. of the bullet?
Thanks for the info.

Muledeer, are you using CFE BLK?

With the tips melted out, can you seat further than what you are doing now or does it hit the lands?

I seat to the last land on the Barnes TTSX 180 with tips removed bullet 2.210 OAL, case trimmed to 1.646,  powder CFE 37.3 Grains,  winchester case, winchester large magnum rifle primer, estimated 2,500 fps not verified yet. I used the BC for the non tipped TSX bullet and the hornady ballistics chart for the following  100 yrds +2.8", 150 yrds 1.7", 200 yrds 0", 250 yrds -5.7" and 300 yrds -11.7" 

18" MDWS Barrel, with a sound forward Brake and a 4 power Redfield wide angle low-pro scope, 6.5 10 round mag holds 7 but I shortened the mag spring by two coils to prevent magazine from swelling when full.
