I voted for Nosler and Barnes, but to be honest I am all over the board.
For 22 cal the Hornady Vmax seems to find an accuracy node easier and better than the Nosler BT, but I feel that I get less chance of a splash wound with the Nosler at 22-250 velocities so I run with the Nosler 55g BT for the 22-250 and the Hornady Vmax 50g for the much slower 222 Rem.
I have two 243s and I am embarrassed to say that I have never been able to settle on a preferred projectile due to the fact that both rifles shoot a variety of them really good. I also use them for both predator and deer hunting and the terminal performance needs are different. Projectiles that work great are:
Nosler: 70g BT, 90g BT, 85g Partition and 90g AB.
Barnes: 80g TTSX and 85g TSX.
The 243 is one of my favorite cartridges to hand load for. It is the Swiss Army knife of my gun safe. It can be used in so many different hunting scenarios.
I will be trying to develop a load for my 260 Rem using the 129g Nosler ABLR.
Larger cartridges such as 308, 300 Win mag, and 270 Win I use Barnes TTSX.
Here is an example of what one of my 243s does with the 70g Nosler BT. The shot in the bullseye is the cold bore shot. The next 3 are all touching. Just a factory take off barrel I bought on Ebay years ago for $60.
