Ive shot dozens of coyotes with that combo! with a MV of just over 4000 FPS they cut coyotes in half and blow rock chucks 5' in the air!!!!

what load are you shooting? I kind of held this one back together for the pic!

Re: .243 cal 55 gr Nosler BT Lead Free

I've been using a pretty moderate load hoping to make my barrell last longer and also hoping it makes the bullet a little more fur-friendly. I've been using Varget or IMR 4064 @ 40.5 grains with the 55 gr BTLF out of my .243 Win. (I believe max is around 45 gr.) Both powders shoot to the same point of impact but I haven't chronographed anything. Do the BTLF bullets copper foul worse than conventional bullets in your rifle?? I spent a lot of time this weekend trying to clean the copper fouling out of my barrell. It was so bad that at the end of the barrell I could see the lands were completely covered with copper.

I did have a chance to shoot a big male coyote with a 58 gr Z-Max bullet out of my .243 using 40.5 gr of IMR 4064. 220 yards DRT. .24 cal entry hole and no exit. Perfect!!

You say the 55 gr BTLF cuts coyotes in half. I assume that means it's not very friendly?? What load are you using?? Velocity?

At 4000FPS+ he's near max with Varget so 44+

I wouldn't worry to much about barrel life IMO. Once you break 1500+ rounds I've read and spoke to a couple guys that accuracy drops less than 1/4, 1/2" which for a want it dead yote gun that's not a lot of spread.

The other thing to consider is are you capable of shooting at maximum ability to even see the change in groups? And a few friends with .243s said they plan too change tubes at 2-3K rnds as the gun works fine for deer till then.

Besides a barrel replacement is a few hundred for a savage or a Rem700.
