I'm sure it has been asked a 1000 times. My friends 12 year old daughter Is going hunting with us this year. I know the marginality of the. 243. But that is what fits her. We are targeting mulie does or any buck For her. Thoughts on bullet and weight. My first thought is Berger Or accubonds (assuming availability ). I don't have any real experience with this round. Shot a few. Know what the ballistic are. Just haven't done any research to put together a load. Seen quite a few deer and cow elk fall to this round. Anyones experience with a quality bullet input please. My concern is since this is a excellent varmint round I don't want incorrect bullet combo (weight). don't know rate of twist yet on barrel. Haven't got that far. Thanks
Nosler 95gr Partition, 39.6 gr RL-17, CCI 200 primer, COL 2.676 (.020 off lands), 2830 fps, ES 6, SD 3, 0.625" 3-shot group @ 100 yards. Not a particularly fast load but a really great youth whitetail load. My son's rifle is a Savage model 10 with 1:9.25 twist.
I would stay in the 90-100 gr. range with a jacketed bullet or an 85 gr. Barnes TTSX. IMR-4350 and IMR-4831 are good powders to start with. An Accubond, Partition, SST, or Sierra Gameking would all be good choices and I've even heard from quite a few people that Sierra's 85 gr. HPBT is lighting on deer although I haven't tried it myself.
I just worked up a load of 42.5 gr. of IMR-4350 under a 90 gr. Accubond and it's giving me under 0.5'' groups and 2900 fps.
I've had alot of one shot kills using 43.0 gr of RL22 behind a 95gr BT with CCI200 primer. Recoil in a 243 is light with any load, it is a great choice for a beginner or anyone for that matter. Shot placement is important,a hit just behind the front leg lets the air out and they don't go far.
I'm shooting a 26" heavy barrel M70, .243 and get great accuracy from the 85-95gn range. The Sierra 85gn GameKing is unbelieveably accurate. So much so it should wear the MatchKing moniker. I have heard good reports from other fellow hunters here in NC about the killing ability of this bullet. I have not shot deer with it but have shot it out to 500yds with several groups less than 2.5". Have not shot it farther than this and not sure I'd shoot a deer any farther than this. I'm loading 37.0gn of IMR3031 w/BR2 primers at 3231fps, getting .381". I loaded and shot 36.5-38.0gn, velocity ran 3213-3363fps and accuracy never got over .752".
I also shoot alot of the 90gn Ballistic Tips w/44.0gn of H4350 & BR2 primers. During testing accuracy ran .1785" for this load at 3180fps.
Had good accuracy with this same bullet and VihtN560 and BR2's. I loaded 40.5-44.5gn w/velocity running 2798-3134fps. I settled on 43.5gn for a good mix of veloctiy (3099fps) and accuracy (.2275").
Good luck. JohnnyK.

Determine the rate of twist of the .243 you are going to shoot. The early .243s had 12-14 twist barrels. The would not shoot the heavy bullets and this gave the .243 a bad rap. When I build .243s now I use 1:8, twist barrels. The 85-100 grain bullets work superbly in the .243. 85 grain Barnes XXX, 90 grain Scirocco, 90 grain Accubond, and the 85-105 grain Partitions. All work great in a fast twist .243.
I like H-4831SSC, H-4350, N-160, and Winchester 760 powders.
