Just bought a 243 an I'm going to load the 55gr noslers in front of h414 for predator/varmint duty. I'm looking at using the 105gr amax in front of retumbo for deer.
Well 46grs (2772fps) of retumbo is starting load and 49grs compressed (2986fps) is max . I know I've read a lot on it and they say normaly the fuller the case is the accurate and uniform the pressure and vel will be so Ill let you know what I can do. I should get out this week and start on the 55gr noslers and the H414
It suprised me to see the 55gr 243 has a better bc then a 55gr .22
The 55gr Noslers would be a good choice as they have a higher bc than a lot of the 60 to 70 gr bullets.

I bought a pack of the Speer 70gr TNT (b/c .282) bullets to try out in my Remington .243, still haven't gotten to loading them yet. I don't have first have knoledge of these bullets, but i have heard some impresive results from people that have used them. The heavier bullet might be better for your twist rate.As to the higher b/c of the lighter bullet, i've searched the Noslers 55gr Varmint BT to be at .276 b/c and Noslers 70gr Varmint BT at .310 b/c. It has allways been to my understanding that usually the heavier bullets have the higher Ballistic Coefficient.
That's usually the case but if you look at Hornady Vmax 65 gr vs the Nosler 55 gr, the Nosler 55gr has a higher BC, also higher than the 60 gr Sierra, I didn't say the Nosler 55 gr had a higher BC than ALL the 60 to 70 gr bullets, just a lot of them.
