I run 34 or 34.5 grains of Varget behind168gr Hornady BTHP's . Same load as the Hornady match ammo you can buy off the shelf. I start at 33.8 and work up when I get a new batch of powder. At least in my rifle it is always between 34 and 34.5 that shoots the best. Good luck

Now a question
Do I need more bullet speed in thin hot air?

Not really, you need to find the load that shoots best and then figure out your adjustment for whatever speed your bullet is going. The Hornady 4DOF app is really good for that.

I live in South Western Florida and I'm sorry to say that the simple answer is "YES" I have had great luck with ALliant RL-17 powder and for hunting .30 cal Horandy 180 grain SST # 30702 bullets. Please re work up a load for down here. OBTW please check out the temperature sensitive powders. Most manufactures have got on this bandwagon !

If u have ur rifle fine tuned, for that rifle, i would just try making adjustments with what u already use. Then if u dont see any difference, try a different powder or bullet or both. I think i would just try to adjust to that jeavier air, maybe use a bit more powder.

One more thing , the closer u are to the water the more humidity u will have and the heavier the air will be. It makes sense to maybe go with speed , but a heavier bullet may work better, just have to experiment with it. Sorry, i cant help any better than that, and sorry about the few mistakes in the last message.

Short answer is no. Has more to do with barrel harmonics. Most likely the velocity you found accuracy with up north will be where it is at down here. This might vary some when changing powders. Different burning rates can change harmonics, but I doubt it will change much. The air also isn't nesc thinner either. Humidity plays a role. Density altitiude matters with everything that flys from airplanes to bullets. This is why bullets shoot flatter in the mountains than at sea level, and airplanes in Denver take more runway in Denver than in Florida.

Yeah buddy... this time try Varget...
I also live in Florida and my to best shooters are 308. I've had great luck 4064 imr one rifle 43.5 gr. Another 44.5. They both been on numerous hunts in Idaho montana and Georgia and have shot extremely well all places and every year when I pull them out in sept and go to the range they are spot on no changes, my son calls them boring I call them sweet. One is a sako the other is a browning Good luck
I'm in Oklahoma and love my 308! Reading through this thread. No one asked the question about how many rounds you down the tube, your throat erosion check or the last time you did a heavy cleaning. When I shot competition in the Navy. When our groups started opening up was a sign of the barrel getting ready to be set back or replaced. Setting it back only gave us another 500 to 750 rounds.
