Re: Looking for a 300 RUM 125 gr TNT Load
Gonehuntingagain is right on. The TNTs have a speed limit and I have found you can not exceed it by more than 200 fps and they will start coming apart.
I have a 300wm that I built just for shooting pds. I have been frustrated by this problem for quite a while. The most accurate 100-110 gr. varmint 30 cal. bullet is the 110 gr. V-max. I have personally shot several thousand of these and like them. They also have a "speed limit" of about 3700 fps. Most hold together if kept under 3750, but you will occasionally get one that comes apart.
In the 125-130 gr. class, I use to use the Speer 130 gr. HP. This will hold together at higher speeds than the TNT, but I wasn't real keen on the accuracy. The 125 ball tip did not impress me either with its accuracy.
I have just started testing the Wildcat 130s. I think this might be the bullet I am going to use from now on. I have cronoed 3715 fps and the accuracy is better than anything else in that weight class. Construction looks like it will hold up to the high rpms, the bc has to be better than the others in this class. Preliminary testing looks real good.
I would recommend the Wildcat 130.
