ScottW - I think a lot there depends on who picks up the telephone.

I'd draw the line at buffalo myself.
I'd rather the 300 at 2,550 or so.

Fjold - I think you're right, at least at the very start, there is a bit of a "hitch" there. But then they seem to float right on down, or so it seems to me. I think a 60 degree inside beveling cone will serve you well, my friend.

I have'nt tryed the TSX bullet but will have to as several of you have had good results.I've actually had my best terminal performance with the 270 + 300 Fail safe.I've noticed no one mentioned them.Has there been some negative feedback that I'm not aware of?I've also had relatively fair results with the Hornady 270 Interlok + 260 Accubond with loads as follows 270 Fail Safe-69.0G. RL-15 270 Horn.Interlok-72.0G. Varget 260 Accubond-69.0G. RL-15 All of these have chronographed at around 2650 MV. I used to crimp my 375 cases,however several years ago I met Finn Agaard at a hunt here in Tx. + in conversation he mentioned never crimping his.Also reading one of Ross Seifreid's articles when he was writing for Handloader,and he stated the same.Anyway,knowing full well that both of them knew considerably more than me on the subject I figured;why reinvent the wheel? I have'nt had any slippage problems due to recoil.However I'm always open to suggestions when it comes to better results.

Your 300's are exceptionally fast and your 270's seem a bit slow.

Using only RL15 for both I'm at 2800 with the 270's and near 2600 with the 300's

These were shot about 15 feet from my Ohler in 60deg F temps

Ah, the joys of reloading. Good thread, interesting. Lot of good info here, and lots of thoughts. Also lots of different rifles, different powders, different lengths, different you name it, etc.

Every load and powder I tried for my .375 has been really good (Steyr). Got a load for 300gr A-Frames and thot that was end of story. Why mess with something that works, I mean shoots -- well under MOA. So a few months ago all this talk on TSXs, so what the hey, I try them out. Yes, I was pleasantly surprised, and am continuing load development.

The one area I'm still working is length off lands, I'm way off at .080 because they wouldn't fit in the magazine, but are still shooting well under MOA. FWIW I'm using 81gr H-4350 w/a Rem 9 1/2 pushing a .270gr TSX, Lee Crimped, Waidmannsheil, Dom.

I'm just using the data from IMR's website for 270 and 300 grain bullets not for the TSX

Frank, I cannot focus on anything I write here or reply to you with that avatar. It's just about the most distracting Avater in the history of the internet. .........Good job!

What was it you wanted? muzzle energy for a .22 rimfire?

fjold
Real world velocity difference between the two is about 200 fps on an average. Mine are normally 2770 fps with the 270's and 2550 with the 300's. Some will get 2600 with the 300's, but I never have been able to. I've had better luck with elk-sized animals with the 270 grain North Fork, for what it's worth mine goes 2770 with 72 grains of RL15.

I thought you may find this interesting. It is a return e-mail from Barnes regarding some questions I had on reloading for Afria. Barnes has some good info on using the X load data for the same weight TSX bullet.

"Hi Scott

Since many of the african animals have their vitalss located between their shoulders, you need maximum penetration. I suggest using the 180gr TSX for the 30-06 (plains game) and the 270gr TSX (more than enough bullet) for the 375 H&H and Cape Buffalo.

Reports from the PH's are very favorable for the TSX bullets.

Most of your shots will be less than 300yds and therefore the trajectory differences won't be an issue.

We Aim to please, reloading is a great hobby, enjoy it.

Heck, if we're using our .30-'06's now to shoot buffalo, why not a 270 gn TSX out of a .375

Regarding loose bullets, I did find the Lee Neck Sizer's decapper mandrell loaded bullets a bit loosely. I ordered smaller mandrell from Lee for $5 that was 0.001" smaller - much improved feel.

I have to second Jaywalker's recommendation. I wanted to seat some bullets further out than the cannelure in my .375 H&H and when I did recoil would move them.

The Lee Factory crimp die fixed it.
