My 20" flat top with a 512 mounted on a LT110 is sighted dead on at 50 yards (1inch group),what can I expect my point of impact to be at 100,200,300 and 400 yards?
Go to www.10-8forums.com search engine and type in “trajectory” and pull up the “.223 trajectory chart” thread. You can also click on this link to get there.
This is what I’ve come up with using a 3000fps, BC of .344 and a optic over bore of 2.75". It’s not exact but close enough that it gives a pretty good idea of what it’s doing.
If you chrono your rifle, measure the optic over bore height and find the accurate BC of you round you can more accurately find the ballistics of it using the ballistic calculator over on www.handloads.com
Thanks to all.
