Might work well on Texas deer, I don't think they get over 200 lb do they?

Yes. They don't often get much over 200lbs down here; at least that I have seen. I have seen a handful go 220-230 lb, but its not very common.

.243 Vmaxs have performed well for me on deer, but nothing replaces a good rest and a well placed shot. Most the deer I shoot are less than 250 yards away and I always try to hit them in the heart.

Wolfie I ran some 53 gr Vmax this year thru a .223. They do fine on coyotes. I think I had some odd angles I don’t recall. Non went thru that I saw.

I also ran some 95gr sst thru a .243. On a deer hit broadside it broke a rib going in, going out, and stayed inside the offside skin. Took out the lungs. There are other bullets out there that would have cleared thru and left a better blood trail had one been needed. This bullet left a dinner plate size of damage to the chest area on the entry side.
I’ll add that I will no longer buy Hornady. Of the case of 53gr I bought, out of three opened boxes I’ve had 7 misfires. The primers are set too deep. Payed too much for those for such poor quality control.

Getting back to your question my favorite coyote round out of my .243s is the federal 55gr ballistic tip. It flat puts them down coming in from any direction. And it’s fast. I’ve taken antelope and deer with that round/bullet and it gets it done tho it’s not my first choice for that caliber going after bigger game than coyotes or maybe lions.
