geting started on the 'Click method' ??

[500YardHog]

I have been shooting groundhogs for a few years now using the "Hold over method " and as shots are getting out to 500 yards plus its getting harder and harder to judge hold over.I'm starting fresh this year with a new .243 and was wondering if i can go to town as is or do i need a 20 MOA scope base to get the clicks i need .I have a cooper Phoenix with a Burris Sig II mounted on a standard base.

You shouldnt need a tapered base with a 243,thats a flat shooting round.I have one on my 308 but thats alot slower.

Good guess ! its a 75 Vmax at 3450 - 3500 .I do already have Burris rings so that Will be the way we will go.
Thanks for the help!

I use the Burris Signature Zee rings, and set up the scope so the 100yd zero is close to the bottom of the elevation. This typically works out so that the elevation bottoms out at -2 or -3 moa below 100yd zero.

Then I set the elevation dial so it says "0" at 100 yds.

Then I make my click charts from there... so 500yds zero might be 16.3 moa... so if the elevation dial is 10moa, I dial "1" plus "6", and three clicks more.

I can find my way back to my reference point even in bad light.

It is not necessary to have your shooting distance in the middle of the elevation range - it has no effect on anything.

Just thought I'd throw in my two cents: Try this site if you don't have a balistics calculator already.
