It's going to depend on the twist rate of your barrel. TC Contenders, Encores, and NEF Handi rifles have 1:12 barrels. They will shoot 55-60 gr. bullets well. Normal hornet twist is 1:16 and maxes out at about 45 grains. I use a RCBS 55gr. FP mould in my TC and 1:8 AR-15. It throws bullets at .2255, plenty big. For the slower twist, Lyman makes a little roundnose mould that looks like a .22LR bullet, and NEI make a couple of lightweights. Not much else out there to choose from. I also love Lee collet dies for use with cast bullets since you can control the neck tension to some extent by how much you tighten the sizer down. The Hornet makes a great cast bullet cartridge, since with the heavier bullets you can run it at full throttle with good accuracy, or drop it down and duplicate rimfire ballistics. Good luck!
