I,m looking at the .45 cal Bullpup. I find many reveiws on them on there power. But very little on how accurate they are at 100 yards.
l know a $$660 gun can not comparing with some of these over $1000 rifles. But for you that have one what kind of groups can a
guy really expect from on. I,m not daddy big bucks, just a retired guy on a fixed budget So that’s a lot of money to me. But .45 cal
is what I’m looking for, & I know they pack a lot of power. But maybe I,m asking too much at 100 yards from this gun? Your comments
please.

I believe Mr hollow point has videos on this model on YouTube. Not sure he shoots out to 100 but to 60-70 with good results. For hunting I personally think 100 is a bit much. I have one in .357 and it does work. It isn’t easy to shoot accurately though. The trigger is horrible and these guns with the combo of long barrel and slow projectile speed aren’t forgiving. I believe the newer ones are pretty much all sold with the even more powerful valve and spring installed which in my opinion is completely unnecessary. My earlier version 357 puts out well over 300 fpe. No idea why the need for the extra power enhancements that aren’t going to make the gun easier to shoot. The stock power one also doesn’t need a high fill pressure either. Three good shots off like a 3200 psi fill. If you can find one in stock I would ask for it to be set up stock without the valve and spring.

@Fly If you ask @Cheplicki (Michigan Airgunner) he may know. It may also be worth watching some of his AEA videos on YouTube. He has shot them pretty extensively. He tests ammo in some vids. In others he's hunting with them. Which .45 bullpup are you talking about? The Challenger? Challenger Elite?

Yeah I forgot about Michigan airgunner. I believe he actually took a deer with one at 90+ yards.

.510 Challenger was under 2 MOA in somewhat challenging weather conditions (13 F, wind gusts), which is not bad. In a more favorable weather and more relaxed body posture I think I can get 1 MOA.

But the factory barrel was bent badly, so no accuracy out of the box. And the replacement barrel was bent, too. Had to fix them before getting 2 MOA. https://www.airgunnation.com/threads/shot-my-510-challenger-bullpup.1297761/ At the end barrels is what brings the accuracy.

What would cause the barrels to be bent? Was it a factory flaw? That’s is a first for me, don,t question you, it is
just something I have never known happens.

Factory barrel looks like it was warped during cooling. Like heated up during boring and then a splash of oil/water dropped on the barrel.

The replacement barrel was simply bent in two spots.

Both you can see by measuring the runout across the length of barrel and calculating the first derivative. If you get straight line that breaks at an angle - there's the high point, which indicate the barrel was bent in this spot. If it's still a curve then it was warped by heat stress.

VTL I went & viewed your thread on this bent barrel thing. Being a retired tool & die maker for many year
I never knew this being a problem with gun barrels. But even though I,m a metal worker, I,m not a gun smith.
After reading that thread that was amassing . I must check air rifles now. Then I saw that video of that guy
straighten that barrel & started laughing. But it worked for him. That’s not the way I would do it . But it is great
to know this stuff. That what’s great about the net. Sharing ideas. I also learned a lot about AEA guns. I have two
stander ones a big bore .357 & a .25 . I,m going to check my barrels see how far they may be out. I will let you
know. Thank you for the info. I,m still a green horn so to speak. like I said I,m just a guy that likes to shoot. This
air rifle thing is still a learning thing with me.

The short answer is that 100yd groups will probably be somewhere in the range of 2 to 10 inches. AEA is a gamble though and some of us have gotten lemons. Finding the right slug is another big factor, and you may need to try many slugs to find one that cooperates.

It's an unregulated gun so you will only get consistency if the tank is filled to the same pressure for every shot. Otherwise followup shots will strike the target elsewhere, usually lower and lower as tank pressure drops.

Cheapest .510 slugs are like $.30/ct. Good ones are $.50/ct. .45 are cheaper, but not that much. Refill time after two mags (2x6) is about 20 minutes with portable 12v pump. Shooting groups for leisure is not for big bore guns unless you bring air with you. A lot of air at high PSI.

For deer at 50-100 yards 2x2 groups is fine. 4x4 is fine, too.

When the barrel is bent the worst thing is not the lack of groups consistency. No, it will shoot more or less fine at a fixed distance. But you set the scope at 50 yards, move the target to 100, and can't hit the paper target at all. The slug flies a curve to the side, like there's extra gravity force pulling the projectile in the plane of the crooked barrel. And with pressure and FPS dropping, the curve changes a lot, too. So no real life predictability where this slug may go.
