I have a Contender with a 22" bull in a 17 rem. I am having good luck with 20 gr V-max and 25.5 gr of H380 (vel 3780 out of my gun). I use this load for shooting P-dogs.
As I said works good in my gun, try it at your own risk in your gun if you would like.
A friend of mine is using Varget and 20 gr V-max in his and is getting good results, and he is pushing them faster then I am.
