hummm whats wrong with the 100 grain ballistic tip was thinking about the 100 grain ballistic tip.. just asking??????

There is nothing wrong with the 100 grain Ballistic tip. I have loaded it in my 250 Savage for years. However I would not load it in the 257 Roberts to its full velocity potential. The 100 grain might be a little fragil at 3100-3200 fps. I load it to about 27-2800 fps in the 250 but would go to the 115 for the 257 Robert. I may be wrong and the 100 gr would be fine loaded down a bit for deer.

i was thinking about 100 grain ballistic tip.... imr 4350 .. 41.0 grains about 2694 mzl vel..i think it might do the job on deer..

You bet. That load should work real well. I would bet it would be a tack driver load as well. I don't like to load the lighter bullets to real high velocity. A guy is just asking for bullet failure.

I had the 100 grainer shooting over my chrony a little over 3100 fps. I shot a doe at about 70 yards and hit her behing the shoulder in a rib. The bullet blew a hole in the hide and broke the rib but didn't penetrate any further. I hit the doe again on the run with a spine shot as she was heading up the mountain. I shot two feral hogs on the day afterwards that weighed no more that about 80 lbs. One was a head shot that dropped immediately and the other a shoulder shot that blew up on the shoulder. Requiring another shot to put the animal down. This is why I don't recommend using the 100 grainer. I have had good penetration on deer and feral hogs with the 115 gr. If you do decide to go with a 100 gr. try loading to a lower velocity or go with a Hornady Interlock, I have heard better success stories with that bullet in 100 gr.
