Pass throughs do make for much better blood trails on any non drt's. If I had the option, I'd prefer load strong enough to pass through. That said, slugs do have higher than average drt's.

The 3" AccuTip has a bit more get up and go. The Federals have been effective for me too, but they seem to have a little more drop than the Remington.

Except for arrows I simply don't worry about pass throughs...

A lung shot deer is going to die quickly and usually drop within 75 yards...
There will be blood after a few yards as they will bleed out of the nose and mouth...
Even with pass throughs sometimes the exit wound gets plugged with other matter...
Typically bullets that stay in a deer create a wider wound channel and drop the animal
faster...

If you want to drop them on the spot, go to a high shoulder or neck shot...

I did miss speak....
 

And I posted the article so everybody could read it. I use shotguns for home defense, I use my .444 when the going gets rough in the swamp and Bear.

Myself and my friend both have the 220f both set up the same, same scope, same mounts, same ammo, remington accu-tip 3", both of us shooting the same groups. The first week of December 2012 my friend shot a 375 # dress weight bear at 60 yds., the bear went 15 yds.

YEAP!!! I have the same slug gun...its AWESOME!!!

The mast crop has been good, and we had a mild winter last season. It has been my observation (after taking 7 deer this season) that they seem to be "fat and healthy". Maybe this has effected the penetration.

As for blood trails, I have had very little. One dropped almost right away, but the other two did the "death run". I found little blood for the first 50-75 yards before finding the deer over 100 yards away.

My bullets were mushroomed, no as symmetrically as the picture posted, but expanded and retained mass.

I would hate to learn my lesson the hard way. I'm new to slug guns so I don't have the experience that many of you have.
