In the 40 odd years that I have hunted hogs and deer I have killed over 100 deer and God only knows how many hogs with the 100 grain partition in a .243 Winchester with 40 grs of IMR-4350. I have used Winchester 88's, Remington 600's & 700's all of them shot the 100 grain very well. The only thing I changed over the passage of time is I went to a CCI BR primer, it seems to make the groups about 1/4 inch smaller. I do not hunt with the 243's as much as I once did, now the grandkids get to use the 243's. A few years ago I ran across a very slightly used .240 Weatherby MK V and have enjoyed it on a few hunts, it shoots the 100 gr partitions into 1/2 inch three shot groups at 100 yards. Before deer season opened last year I got a 100 pound hog at 310 yards with the Weatherby, a bang flop. That was a good opening to an even better hunting season.
Good shooting,
Marcus.
