What is the most devistating round you have used in the 243 for deer? What is your go to round for a 243 for deer and why?

My grandsons use Hornady 100 grain BTSP. They havn't lost a deer yet with it.

Over a 10 year period I tried about a dozen different factory rounds, in a nutshell, it didn't matter, they all killed deer...

I went back to the 100gr CoreLokts...Now if you are hunting fields where ranges can run over 200 yards, look at the Federal Premium 85gr Sierra GameKing HPBT...It's flat shooting and excellent for long range deer/antelope hunting...

Other than that, whatever your rifle likes in the 90-100 gr factory loadings...

x2 on what nchawkeye said, 'cept I'd push the 100gr. further than 200 with excellent results. 200 yards is still a chipshot for the .243.

Ditto. I've had a pile of plain-jane 100 gr green-box Core-Lokts around for years. Never had an issue with them on whitetails, muleys, or pronghorns. Once I finally send them downrange, I'll probably load up 100 gr Hornadys, but I wouldn't hesitate buying Core-Lokts if I needed to.

I've never shot a deer with a .243 but have 4 friends that use them. One uses Winchester 100 grain Power Points and has great luck. 2 of them use Federal 100 grain soft points, and 1 of them uses Hornady 95 grain SST's. The one that uses the SST's used Winchester Power Points in the past and had good luck with them but ever since trying the SST's he said they are the most devastating bullet he has found. He loves them. I think I may try them out in the future. The soft points from any of the main company's seem to work and be cheaper if you are on a budget.

i like hornady 100gr btsp or federal 100 gr sierra gameking.
both have punched some nice holes

I've been using the Hornady "Custom" 100 grain bullets in my Browning .243 Rifle and they have put down every Deer I've shot with it!

Started out using the Sierra 100 gr gamekings when I first started using the 243 win . Then I got to talking with a tech.rep from Sierra and he recommended the 85 gr hpbt gamekings . Worked great maybe to well so over time I went looking for a better bullet . Found the 85 gr Barnes X bullet and haven't looked back .

i use Remington 100 grain Core-lokts. they are the only bullet that shoots flat out of my Ruger
