With any luck, I will be purchasing either a TC Contender or Encore frame within the next 5 months or so, and I want to make it a varmint gun. I plan on shooting ground squirrels primarily, but I am sure I will shoot some rockchucks with it as well. However, I am having a hard time deciding between the .17 Mach IV, the Tactical 20, and the .204 Ruger. The way I see it, there is both advantages and disadvantages to each. What I am looking for is a cartridge that:
1. Will allow me to see my hits through the scope.
2. Will not burn out my barrel in 1500 to 2000 shots.
3. Will allow me to make shots out to 300 yards.
As I see it, the advantages and disadvantages of each are:
.17 Mach IV - Advantages - Uses less powder, won't eat barrels, low recoil will allow me to see shots, and it SCREAMS!
Disadvantages - Light bullets used may not reach to 300 yards with enough energy to dispatch rockchucks, forming brass requires many dies (expensive), buying pre-formed brass is expensive
Tactical 20 - Advantages - Uses .223 cases as parent case, has heavier bullet selections than the .17, will most likely be better over longer ranges than the .17, and it SCREAMS!
Disadvantages - May not be able to see hits through scope, need to buy expensive custom dies, may be a barrel burner (I am unsure of this).
.204 Ruger - Advantages - Eventually will have factory brass for handloaders, available factory ammunition, has heavier bullet selections than the .17, will most likely be better over longer ranges than the .17, and it SCREAMS!
Disadvantages - Parent case brass is harder to get than .223 brass, may burn barrels quickly, may not be able to see hits through the scope, and at this time, dies are still a little on the expensive side.
Now, I know that dies are most likely going to be expensive, no matter which caliber I get. That aside, can anyone provide information on their personal experiences shooting these rounds, and help me to make this decision? I really want to have one of these calibers by next spring, so I need to get to deciding soon!
Thanks in advance,
Loki
