Guns, Bows, Shooting Sports, and Hunting 25-45 Sharps

[CBlack]

Caught wind of this round 2 years ago at SHOT and was intrigued. I've had mine built for about a year. It's taken that long to get some load testing (lack of chronograph until recently). I wanted something different that would be simple to build and without a lot of case work. The 25-45 is a simple resizing of the case. And it packs a punch.

All reviews I've read say it's a fantastic varmint round. Should a nice hog stopper. With the Barnes 80gr and Sierra 90gr BK, deer go down as well.

I've gotten the following through my 18" barrel:

70gr Sierra BK ~2935fps with 27gr R10X
75gr Hornady VMax (Bulk packs through Midway) ~2993fps with 27gr R10X and ~2907fps with 24gr IMR4198
85gr Nosler BT ~2650fps with 22gr R7 and the same with 23.2gr IMR4198
87gr Speer Hot-Cor ~2864fps with 27gr R10X and ~2814fps with 24gr IMR4198

These were chrono'd with my new Oehler 35p. Average of 5 shot groups.

I've bumped up the charge on the 70, 75 and 87 gr bullets with 4198 and R10x. Hoping to chrono next week. I've also ordered some Barnes 80gr bullets to try out. I have some 90gr SBK to try as well.

I'll try and keep this and the other thread updated. I'm determined to hit 3000fps consistently with the 70 and 75 gr bullets.

All loads with IMR4198 have some room to grow as well.
