Quote from: Nomadic Pirate on September 17, 2021, 03:53:14 PMBest medium to test bone penetration is a dry Phonebook, tape it so it doesn't spread,Easy to peel of pages and get a reading that is the most consistent because the medium don't change.I'm not sure if I could even get enough phone books to do that here. Our phone book is maybe an inch thick, if you can find one. Quote from: JimD on September 17, 2021, 03:37:38 PMDJ,You may be right but I am not sure what your picture displays. Is it penetration in solid wood? I prefer to use MDF or plywood because solid wood varies a lot in density. But something like 3/4 inch plywood is a reasonable guess at what it will take to penetrate a pig or deer skull. But it is important that you have that penetration at the distance you shoot the animal. My Avenger will shoot through 3/4 at 25 yards but will not at 100, for instance. I have not tested in between distance. If you have much more than 3/4 inch penetration in solid wood at the distance you want to harvest game, then I would agree that projectile from that gun is sufficient. JimThat was a rough cut spruce 2x6 cut off end that was split in half by another round. In the photo it's hard to see, especially on a phone, but the slug penetrated 1 1/4" and did not pancake or deform much at 25 yards. It's not so much about the penetration as the deformation of the projectile. You mentioned that many slugs have poor penetration, just wanted to show that the NSA slugs have phenomenal penetration. 3/4 hardwood plywood doesn't stand a chance in stopping my Eagle Claw .25 with any ammo at 25 yards. I have some one gallon containers that I filled with sawdust to test as a lead trap and it could stop the smaller slugs, even at full power, but not so with the 33.5 grn and heavier slugs.

Many slugs are designed to expand a lot and penetrate not a lot. Even placed properly out of a gun with enough energy I question whether a quick expansion slug will penetrate the skull of a larger animal. To me it comes down to:1) Do you know where to place your shot2) Can you dependably place it there3) Will your projectile penetrate the skull (and brain)Need all three.This is a 26.8 grn .249 NSA slug, I'd say this satisfies your requirements if you were looking for slugs.Not that I care but that shot is with the grain and it looks like Douglas fir or pine, a really softwood...so naturally it would go further in. How many inches in was it? I shoot those NSA slugs. They are awesome.

I shot many hollowpoint bullets into hard mediums like the above stated Packed Phonebook and rather then expand they cave in

Our phone book is a 5x8"-ish about 3/16" thick. I don't think they all add up to a single edition when we lived back in NJ almost 15 years ago.Another option might be to get a ream of copy paper from Staples. It won't penetrate as far as into a phone book, but it will be VERY consistent.Andy
I do get plenty of agri-supply catalogues, could stack those together, thanks for the tips! We also get a lot of shipments from amazon. Does stacked cardboard work just as well? I was shooting boxes full of paper and debris with the Daisy 901 to contain the BBs so my chickens don't eat them. Not that the BBs would hurt them, just would rather not have them eat metal.
