I some how do not see what testing 70-80-90-or 100gr would prove for me since I start looking for loads that work with at lease 100gr of BH or 110 of 777. I have heard of people having these problem before and wondered about it. Is it possible that light loads do not open the bullet ? It sounds like Falcon uses lighter charges than myself and has good results, for a while I thought maybe they were not hitting them in the right place, now I am wondering if there is a mid range load that is non workable.
Chap what size load were you using? I personally have to hold the load I use on the 250's down to keep them from fraging unless I use the more expensive bullets, but I like to shoot them at 2200 fps to which is a little beyond what most people use. Lee
