Good info so far guys. BSL, I will try that with the scope. I am using a program or calculator that is in an excel spreadsheed that I downloaded from here.
Free Ballistic Calculator (FREE Ballistic calculator)
FBC-v3.xls is the file name.
I have the option of setting the click value and I also have the option of setting the MOA value against an inch. Apparently not all scopes agree on how many inches an MOA is. Who'da thunk it.
I have also used JBM a lot as well as some of the calculators that some of the bullet makers have on their sites. And have come up with similar results.
bigngreen, do I know that the target in question is really at 600 hundred? Well, that's what it says on the sign behind the shooting bench! LOL. The site in range is 200 long, behind that is a deer, the behind that is an antelope and bear and behind that is another deer. The sign at the range says deer 300 bear and antelope at 400 and mule deer at 600. Have I actually measured it or used a range finder in it? NO!
I suppose that could be a problem as well huh?
Moman, I am having problems with the steel that was listed above and they are life sized steel. The steel that I don't seem to be having a problem with is regulation sized steel silhouettes. Pigs at 300 meters, turkeys at 400 meters and rams at 500 meters.
Quick load data I am shooting 180gr HPBT SMK's using Federal brass, CCI 200 large rifle primers. And somewhere in the middle I put 41 gr's of Ramshot TAC powder. Ramshot powder lists that powder with 180gr HDY SST bullet with a low charge of 38.5 gr at 2325 fps and a top load of 42.8 gr's at 2585 fps. That is with Ramshots rilfe with a 1:12 twist and 24" barrel. Mine is 1:10 twist and 21" barrel.
I have to go to work today and will be at work for the next day in a half. I might get on tonight as time permits.
Thanks for all the help so far.
