Try a 55 grain Nosler BST at 4,000 fps.

.243 works nicely on jackrabbits. These were from my son's first hunt.

Dang, you can only upload one per post...

These were taken using Remington Express 100 Gr. PSP Core-Lokt's.

Oh no I didn't feel you were getting on me.Texas doesn't consider them game animals and I don't think our jack rabbits would be worth eating on their best day,they are varmint.I will pass on cotton tails with hopes of a good freeze followed by snow,then I eat rabbit! I love pheasant hunting after a good snow...every brush pile has a bird or cotton tail and they are fed on corn or wheat.Now thats good hunting and eating!
