4.5 fpe, under 6 yards, 0 pellet expansion fix tested / confirmed

[sharroff]

I've been shooting chipmunks and squirrels at 6 yards and under using my 10M pistol, as my .177 rifle scope doesn't focus in / turret adjust down under 5 yards. I have no problems with a immediate kills on a headshot, but was getting pass throughs and not immediate takedowns on chest shots. Just .177 holes where I point, as there is 0 expansion on Predator Polymags (.177 8 grains) at that speed (490-500 fps).

So, I wondered what would happen if I flipped the polymag and fired it backwards. Impressive results below on 10% ballistic gel. Firing normal orientation, the pellet keeps it's .177 size. Fired backwards, they open up to .268 and stops at about half the distance (~1.5" down to ~0.8") into the gel!! Accuracy at this range is not impacted.

I followed up the test on a chipmunk and got a small entry hole with a large exist hole with its internals now being externals. Didn't think we needed a picture of that, but could post if needed.

Obviously it shoots that way straight enough! genius! What a interesting and effective customization for the need.

Sounds like it’s accurate enough! Btw the daisy hollow point has a huge hollowpoint that most likely work in this use case

Great experiment! Now I can try using low velocity, reversing the pellet for extreme expansion, less noise and more sure kills for us backyard hunters and pest control Thanks

Yes sir, that will do the trick on soft tissue at close range. It reminds me of Joe Wayne Rhea shooting some Daisy pellets from his FWB and getting a poor group, then shooting five JSBs loaded backwards and getting a better group. If memory serves, the distance was 25 yards or so.

im glad to see you caring about the nature of dispatching pests ,if they gotta go ,it's always' better to do it quick,i like the expiremant good work,pat

For what its worth, i've only tested this out in my Steyr EVO 10 pistol shooting at distances up to 6 yards, at which point I switch back to my .177 rifle.

At 1-6 yards, i doubt there is much time for the ill effects of flying backwards to manifest themselves in significant changes in pellets point of impact (I saw none). At further distances, I'd expect accuracy to suffer. Maybe in the next few days I can try this in my AZ custom Steyr rifle (19 fpe, and pellet on pellet at 50 yards).

Cool idea

Very cool idea!

Definitely going to try this!!

Please, do post your test results. Thanks.
