What do u think the best bullet is out there now for varmint hunting? also any info on the hornaday 45gr bullets how do they preform.

Midway has their dogtown 34 gr bullets on sale,in the 100 packs, greatest buy, if you are only using them for varmints.

I really like the 39 Sierra BK. They shoot great in my Kimber. Apparently they stabilize in most rifles when 40's may not, I would think 45's would be iffy. Working up the perfect load is part of the fun. Get some of each, and good luck in finding the perfect load.

I used the Hornady 40 and 45 Gr bullets last hunting season for Coyotes, Coon, and Crows. very impressed and Will use them again this year. I used the 204 Ruger and 20 tactical

My rifle (Savage LRPV) likes the Berger 35 HP.

39gr Sierra's are the best I have tried so far, from feral cats to prairie dogs. I have had three 204's, two with a 1:9 twist. If you avoid the 32gr Bal-tip's in the fast twist, it provides a much more usefull weight range in the 204Ruger.

For the bigger critters like yotes, the 35 and 40 gr bergers and the 45 gr hornady sp are ideal. I have some 38 gr wildcats to test out as well. I believe these will be my ultimate yote bullet for both of my 204's.
For the smaller critters, the ballistic tip in hornady, sierra and nosler are great for blow ups and red misting. I have done some testing with the 26 gr varmint grenades and so far at close range have worked very well. Havn't tried them at longer ranges yet. So far the most accurate have been the 39 gr sierra bk's and the 35 gr bergers.
