Yeah, I would think that only 55 FPE remaining at 75 yards would be pushing it on a Coyote, they are pretty tough to kill.... The exception would be a fusebox shot, of course, but that is a tough shot at that range.... You won't have much more retained energy than a .22 Short....

Honestly I'm not 100% sure if it'll be even good enough for that but that's my hopes. 50yds should be no problem and it would be head shots. I have a .223 Rem 700 so I have a gun capable of coyotes. But more testing will be done before I ever attempt it and obviously closer ranges before stretching it. I've heard of others taking them with .25s with less power at some distance but we'll just see how it turns out.

If you stick to fusebox shots, you should be OK.... provided you take into account the anatomy of the skull to avoid deflections or missing the brain.... I always find studying the skull to be a great help.... and aiming for the exit point on the far side allows for better visualization of the bullet path.... On most carnivores (in fact many animals), you have to avoid the sloping forehead on straight on shots....

Hope I'm not out of line here. Seeing I'm not with the PC crowd.

If you have a yote problem AFAIC anything goes. Ever see 20+ ewes with their stomachs tore out? Boiler room shots work, they're just not DRN. ;)

Buncha BB guns that I don't get to shoot as much as I like. Building duck boats now that I'm "retired".

You make a good point there John they attacked one of our calves taking it's tail and eating the hawk down to the bone a few months back and eat all the hoses on the pivots. Luckily I was able to nurse it back to health. Couldnt imagine the sight of all those ewes killed by them. A polymag to the boiler room would probably do it good enough to take it out might not be as quick but hey when hunting big game with powder burners not many just fall over either so I won't feel too bad.

Here's some accuracy pics. I have some horizontal POI shift which is obvious to see and I noticed this yesterday while hunting. It's very consistent it was alittle to the left and then dead on at the end of the shooting. That being said I'm extremely pleased with the up to down POI. Very very consistent so I know it's accurate and it's not the pellets or barrel. Just need to mess with the Set screw barrel band and see if it's too tight.

Left target has 13 shots in it shifting from left to right. The right one has 7 shots 4 in the middle and 3 to the left. Also noticed this gun needs a tighter hold compared to my .22 because of the recoil.

EDIT: just realized the pic is upside down  ???  Has now been flipped correctly so description makes more sense

The reason I ask is simple. My groups (comparatively) from my .25 are smaller at 25 yards using PolyMags, and smaller at 50 yards using JBS Kings.

Interesting find. I do know polymags at longer ranges open up and aren't quite accurate. I was really hoping that the polymags would be accurate in this gun and after testing I thought there goin everywhere I don't like them....BUT looking at my previous groups of them I realize there probably not as bad as I'm thinking they were and we're following the left to right shift with the pressure changes like the JSBs do. So I will be testing them out again and will do comparative 25 and 50yd groups once I try Motorheads foam tape fix.

Allow me to add to this discussion.

I have a 397, and I really like it. At distances under 30 yards, it is dead accurate using PolyMags (7.8 grains). I have managed to hit things out to 50 yards, but if you'll excuse the pun (?), it is hit or miss! But then again, a .177 isn't what one would call a long-range caliber, at least in a 397 pump gun.

I love the killing power of the PolyMags. Things just don't get up and fly away, almost no matter where you hit them. Since we all want to be humane, I just wish the JBS, .25 caliber Kings (25.39 grains), weren't so darn hard!

I agree Alan. I've hunted with the polymags and they are devastating and wish they were accurate in all my guns as that's all I would shoot but like you said 50yds is hit or miss with them. I also agree that the bigger caliber JSBs are rather hard. Take this for example I've taken a few dove at 80+ yards with my .177 disco tuned at 16.5fpe with 10.34 AA/JSB. There hit and dead that's it. My .22 with JSB/AA 18.13gr tuned at 29fpe and I've killed hundreds of birds from 10-115yds very few needing follow up shots. Both the JSBs are very soft pellets and deform nicely in both those guns. Now with this .30 tuned at 70fpe I had multiple with great shot placement and the birds just walk off quite aways unless it's a sparrow. My first shot was on sage rat at 25 yds right in the chest he dropped like a rock and was kicking around 2 min later I go to get him and he's gone and crawled into his hole. Next one on a dove at 30 yds side shot in the middle of the chest. 5 min later I go to get him and he walked 25 yds before stopping. Huge hole right where you want it yet didn't die right away and had that quite a few times the other day. Not sure what it is but my .177 and .22 kill the birds better and why that is I'm not sure. But shooting the .30 through 1/2" plywood the pellets go right through and not as much deformation as one would expect.

This speaks wonders...free floated the barrel again and poi shift disappeared. Here you go Alan 25yds 5 shots each. The ones at the bottom were before I sighted the scope. Left side is JSB 44.75 right side is Polymags. Bottom Polymags were 4 in same hole and 1 flier. Then they went everywhere on the higher one...looks to me like no need to compare them at 50yds but will get a 50yd group on the JSBs when I can.
