1) If you don't find the deer you don't really know where it was hit...I hear all the time about my little .243 being too light for deer...I've used it since 1980 and have killed about 200 deer with it, losing one...

2) Were you using the bonded Shockwave or the standard one??? What was your powder charge...

3) Between a couple of buddies and myself we have killed about 25 deer with the standard Shockwave...Our powder charges are 90-100 grs of Goex, Pyrodex and 777...My longest kill was 147 lasered yards...We have had some lung shot deer run further than we hoped but I don't remember any going over 125 yards...Frankly most of mine drop at the shot due to a high shoulder shot...I'm getting too old and cranky to try to recover deer shot in the swamps and cutovers on our farms...

4) Of the 3 bullets you mentioned the Shockwave is the best choice for that 200 yard shot you made...It's interesting that you made a good shot on the longest deer but not on the 2 closer ones...

5) I have killed 5-6 deer with the 300gr Barnes MZ...It and the 250 Barnes are awesome bullets and give great blood trails when deer are hit in the lungs, exit holes are low and guts don't plug the hole...But...I tested the 300 Barnes with 100grs of powder and the 250 Shockwave with 90grs and the Shockwave was 5-6 inches flatter shooting at 150 yards...That 200 yard shot you made with the Shockwave would have been much harder to make with the Barnes...

If your shots are within 100-125 yards a hollow point bullet might make more sense than the Shockwave...All these bullets are trade offs...The good thing is, it's the off season and it's fun to try different bullets/sabots and powders...

Heck the answer might be to invest in a Savage, shoot the .452 300gr Hornady XTP in front of smokeless powder and push it up to 2200fps, then those 200 yards would be a piece of cake...
