I got some 29.5 NSA 25 cal slugs that my FX Impact MK II really like at 972 fps. 1 inch groups at 100 yds. and about 1.5 inches at 150 yds. These are the first slugs that really shoot well. In the wind they are really good with as much as 2/3's less drift in the wind over JSB King Heavy MKII. So Decided to test the expansion on the slugs so I took a 3 litre plastic soda water bottle filled completely with water and set it out 80 yds. and the result well lets say no so great. No Expansion just compressed the slug to about half its original length and thats about it. Iam sure penetation is alot better then pellets as far as that goes but was hoping for more expansion of the slug. The piece of plastic from the bottom of the bottle and the slug was both inside the bottle which made for a easy recovery. What do you all think about this have you had same experiences or not. 
NSA 25 cal 29.5 Slug Expansion Test

It looks like you're all set when three liter bottle hunting season opens! Plenty deadly. Even for the big bulls.

I’ve seen the same results from the slugs. There ability to buck the wind definitely makes up for there lack of expansion.

Try on pests, I thought the same thing when testing them but the hard plastic bottle causes the tip to close instead of expand in my experience. First photo is 5 @ 50 outta my cricket .25 @ 880 fps. Second photo is 5 @ 100 in wind(5 shots just above thumb!), and third is a sparrow that would not leave our chicken food alone... no more! ( 47 yard center mass shot and a wicked pop to boot!)
My advice is try them on pests, I got night and day different results shooting thick bottles to test expansion and then testing on softish mediums that more resembled pests (an apple or a potato). They do amazing bucking the wind too, my longest shot yet with one is 147 yards!

Exciting to see that kind of performance...! Gorey glory!

I had the same experience when testing .22 hades with milk jugs. My solution was to use zip lock bags filled with water. Much better expansion!

I had great expansion out of the 29's DB at 50yds through these cantaloupes, DRT as they say. The lower slug is a 20.2 NSA DB btw.

Got out this morning to do some pesting got 7 starlings and 4 house sparrows longest shot 137 yards shortest being 81 yds also got 4 Ringneck dove at 105 yds for table fare. I have to say the sound of impact even at 137 yds is insanely loud. They fall like a brick. I thank I will stay with these for awhile for sure NSA 29.5 rock for sure.
