Re: Please help me pick the right Caliber

Depends on the length of bullet you want to shoot. (not necessarily weight) If you are going to shoot long 105 grainers, you probably want a 9 twist. If you were going to shoot the really light (short) bullets you might go as slow as a 12. A 10 is a good all around twist. That's why most manufacturers use it. It takes more twist to stabilize a longer bullet(accuracy). Having said all that, it is best to not overtwist as it accentuates flaws in the bullet (inaccuracy). In other words, use the slowest twist that will stabilize the longest bullet that you are going to shoot. There are tables that will help you decide or better yet, just call a gunsmith or barrel maker. Most are more than willing to help.....Rich

For shots between 20yds to 500yds I would want to use a bullet in the weight range of 80 to 100 grains. A 1:10 twist will be sufficient for these bullets. If you want to go 300 yards to 1000 yards regularly, you are going to need a heavier bullet in the 105 to 115 grain class. This will require a minimum of 1:9 and for the 115grn class bullet you will need to have a 1:7.5 to 1:8 twist. These should be the ones to use if you plan on going out to 600+ regularly to keep it on target. IMHO

It would be easiest to just get a 1-8" twist and then try the heavies and see which one shoots best.

Which one of these would you get in 243? Price not a factor, only performance.

If you are carrying in the woods, then I would consider either of the savages you have chosen, but if you are prairie dog hunting and ghog hunting, I would consider the mod 12 for the 26" barrel. Adds velocity and they are real shooters.

I have shot some Rugers, but just not really big on them. They do shot pretty good though. I really like the laminated one you picked. Just bare in mind with the Ruger you will have to get trigger work done to make the trigger lighter.

Savage all the way for me.

Thanks tank, I actually thought i had put that one too. I also just found this and looks pretty good what do you think?

Howa Varminter Supreme & Thumbhole Varminter Supreme

What I want is something for the best precision I can get without going into the big money of a custom rifle.

right now Im feeling Savage.
