RE: First time out with new rifle, and I LOVE IT!
Congratulations.....it seems you have a very fine varmint rifle.
When you start reloading you' ll have a large variety of excellent bullets to choose from. I caution that you don' t have too great of expectations.....I once owned a .225 Winchester in a model 70 and was never able to make a better round reloading than I was able to buy direct from Winchester.
When you start handloading, I suggest you try some bullets from Berger.
