Hi,
I have a .223 Tikka T3 Varmint with 1-8" barrel twist. All information I have read about barrel twist suggest that I should be using heavy ammunition which the 1-8" twist is designed for but as I'm experimenting with different ammunition at the moment, the best I found yet is Norma 40 grain ballistic tip, these I find I can get 1" grouping at 150yrd but anything heavier just cannot match this accuracy. The problem with Norma is the availability of them without me having to travel quit far to purchase them and would like to have an alternative brand of ammunition that I can use.
Do
