I use 75gr Hornady MHP's out of a 24", 7.7 twist, Lothar Walther bbl. Accuracy is great @ 1/4" to 1/2". Terminal effects depend on the specific batch of bullets. The hollow point tips on the first box of 600 bullets were very tight and hardly opened up at all. Very little pelt damage, but some tracking was often required. Most praire dogs that I hit even managed to go down the hole and die. The latest box of 600 have rather open tips and are moderately explosive on P-dogs. The last Coyote I hit tipped over without even a kick, and the exit hole was about 1/2 in diameter.
