First off I'm new to handloading for rifles but have been loading handgun calibers for about a year. I just got 200 55gr varmageddon bullets in 243 from midwayusa. My question is with the total copper jacket they have do I use fmj load data or lead? I've always read to use lead data for tcj in handguns and don't want to blow up my new rifle. I'm using H4895 if that matters. Thanks in advance guys.
