Home Forums Hunting & Shooting Express Rifles and Big Bores Only Hornady Superformance 250 gr GMX ?

I have a new rifle... Nosler M48 Outfitter in 375ruger.

I wanted to use 270gr TSX, but there is a problem.
It shoots accurately, but will not cycle in my rifle well.
The flat surface on the tip of the bullet catches something and jams often.
Nosler said to send the rifle back but might not get back to me in time for my trip. They asked if all bullets did this or just the TSX.

I went to the gun shop and cycled thru some Hornady Superformance 250gr GMX and they fed very well. Not 1 problem.I couldn't make them jam. The tip seems to alleviate the problem. I will likely send the rifle back for the fix, but will likely wait until after my hunt which is the first of June.

Questions for those that have used them:
1. Any problems on plainsgame, including an eland?
2. Any problem using these on a Cape Buffalo?


I've read many positive testimonials of the 250gr TTSX for buffalo and wonder if these Hornady will do just as well.
I could order some of the 250gr TTSX but can't get them locally.

thanks.

Looks like Swift has loaded ammo with the 300 gr A-Frame, In your situation and with Buffalo on the menu, I would be ordering a box of that. If it shoots and feeds well you are done and can stock up. Time is running short.

Just got back and shot my buff with 300 gr TSX. It worked great and I would use it again. And I already had about 400 of the 250 TTSX on hand. I felt better with a 300gr on buff, but that's just me. The GMX would not be on my list for a buffalo but would be great on the plains game. Since only a month to go I'd just go with a 300gr and use it on everything.
