A little patience please on my asking this age-old question...again.

For 6 decades with the rifle SCOPES we had - have always depended on bullet speed to be able to maximize my cartridge's "ethical" LR reach. LR meaning 400 +/- yards. .270 Win, 7 Rem Mag, 300 Win., etc, etc. No complaints. None. DRT's common.

Today's scopes and bullet advances are allowing us to extend our accuracy limits.

My .243 Win has a 1:8 twist. With old school thinking (see my 2nd para), I've stayed with 70 to 80 gr for Wiley. Reason for this post is my wanting to explore heavier bullets for LR varmint work. Target work will of course precede the hunting but # 1 purpose of bullet is for Coyote hunting...maybe out 600 +/- yards.

Your thoughts on bullet?

Thanks.
