Federal has put this out in their vitalshok line. 130 gr barnes tipped tsx. The guy thst wrote the column seemed sensible, so what about coyotes and hogs in florida. Biggest thing I saw going was the high weight retention.

I load that bullet on my 300 WM at 3550 fps. and it is awsome! I shot a coyote at 220 yards and not much damage, but did not hit any bone either. Also shot a small hog, about 30 lbs. right in the shoulder and disasembled the pig. Shot trought 2 big hogs at 130 yards. The bullet performs excellent.

The adavantage to the 130 gr, 308 cal bullet is it will shoot a little flatter out to 500 yds or so, which means you can zero and hold on at longer ranges (only about 40 yds farther than a 180 E-Tip) The disadvantage is that the BC on the 130 bullet is terrible (.350 vs .523 for the 180 E-Tip) I would question their effectiveness on big hogs beyond 400-500 yds.
Bottomline, they are a good bullet inside 400-500 yds for flat shooting, but IMO not much better than a 180 E-Tip, and out side 500 yds they dont even campare to the heavier, higher BC bullets.

I'm a big nuttin that asks questions, so here we go. The guy I was talking to mentioned the same thing. But he said dynamic coefficients held more weight than static dynamics, and this bullet had a much greater dynamic coefficient. That's what he said. I know what he getting to , but not really all the facts that go into this.

I only use the 130's inside of 300 yards, if I know the shots are going to be longer I load the 168 TTSX, you need heavier bullets with higher BC to reach farther.

I'm not sure what this guy you were talking to meant by dynamic coefficients and static coefficients, but there are basically only two things that matter when it comes to external ballistics... velocity and ballistic coefficient. These two factors alone will affect how far down range your bullet will perform effectively (based on opening/expanding velocity), their trajectory, how long it takes them to get there and how much they are affected by wind.
Both the TTSX and the E-Tip are deigned to open down to 1800 fps. If you plug the numbers into a ballistic calc (130 TTSX, BC .350, MV 3500 fps - 180 E-Tip, BC .523, MV 3000) you will see the Max Point Blank Range of the TTSX is 336 yds when zeroed @ 289 yds and the MPBR of the E-Tip is 299 yds when zeroed @ 254 yds, a difference of 37 yds in point blank range trajectory. When both are zeroed @ 250 yds, their peak trajectories are 2.1" for the 130 gr bullet and about 2.9" for the 180 gr bullet, a differenc of .7" This is the ONLY advantage of the 130 gr bullet, period. The muzzle energy of the 180 bullet is slightly higher than the 130 bullet and the momentum is about 20% greater. The difference in both of these forces increase as the bullets progress down range with the 180 bullet pulling away from the 130 bullet. The 130 bullet reaches 675 yds with 1800 fps and 33 lbft of momentum which IMO is enough for deer but not enough for elk. The 180 bullet reaches 750 yds down range with 1800 fps and 46 lbft of momentum, which IMO is enough for both deer and elk. At 500 yds the 130 bullet wil drift 20" in a 10 mph crosswind and the 180 bullet will drift 15".
My concluclusion... the overwhelming advantages go to the 180 gr bullet. An easy choice for me.
Good shooting,

Have you tried the 180 E-Tips? They shoot faster than the 168 TTSX's out of my Sako 300 WSM with RL17 and almost the same with H4350. Maybe it's just my rifle?

Sorry if I misled you a little . Heck to get old and forgetful. What I tried to was say bullet coefficients at static (still) and dynamic (moving). If you know this one and you probably do, Ill say I'm dumber than a first grader. (lol)
