Hey there, I know you are all busy but I’m hoping when you have some time you can give me some input bc I am new the the pcp world and I’m having a hard time. I recently got a Texan Carbine and I’m having trouble getting it sighted in to hit accurate. I’m using a center point scope, Nielsen 290 and 350 HP’s. And I refill at 2000psi. I have no scope riser and my scope is sitting literally ontop of my gun. I can’t reach out to 100 yards accurately. It’s shooting wicked low and very inconsistent. I’m so frustrated. Any help would be very very appreciated. I just ordered a SCBA tank to tether with fill station, a cheapo scope from Amazon and a 11mm-pictanny riser/adapter. I got the gun to hunt and target shoot with. I wanted to be able to maneuver easily in the woods of Vermont to stalk and that’s why I chose the carbine. I reached out to Rick (shooter1721) and asked how far these guns can shoot accurately and he said 100+yards. And although it is shooting wicked low, it still blows apart a cinder block at 100 yards......... I just had to aim wicked night and try 5-6 times before it hit the block, but when it did??? Shattered it. So I know the power is there. I’m hoping my scope and setup was just off. I just want a consistent grouping so I can be confident when I pull it out to hunt this next coming deer season. I know some guys on here are very very serious and know every single thing there is to know about these guns...... please help me. I’ve spent a lot of money so far and am having a very hard time understanding if it was worth it or not because I can’t get a group to form. Shots are sometimes more then 10” part........ and when I’d adjust my scope, the shot placement wouldn’t hardly move......... any insight I will take and use. Thanks guys!!!!

Are you experienced with shooting before your foray into airguns?
A photo of your current set up might help us diagnose your issues.
Mt next question is are you sure your scope is not the problem?

mine has been poop for accuracy too. i get 6" groups at 50 yards, and seems to have an extremely wide ES over the professed "4-5 shots", last one i recorded was 878->674, no way that is gonna group.
the power wheel on mine spins without any resistance at all, up to about line 2.5. I emailed airforce in december, still waiting to hear back...
I did find loose grub screws on the barrel, you might check those!

You will have to sight it in at the yardage that you will be expecting to get shots at deer. Then if you want to shoot further you will have to practice to see how much you have to hold over for a further shot. In rifle season most of the deer I’ve taken in the mountains were still an average of 30 yards Although my gun was easily capable of taking them out to 300 yards.Some people have to do a lot of trial and error testing with slugs to find ones that will shoot good in the rifle.

Check your scope rings, all screws on the gun, clean the barrel, lower the hammer-spring a lot and start out with light ammo first. Those guns have a thin layer for grease that turns to tar if you shoot it with cleaning it. Center point are known to not hold a zero. You can buy cheap iron sights for the Texan for $10 on Amazon. Start off with that, then put the scope on to find if it's zero is jumping around.

I talk with Nick Nielsen about that a while ago and he told me:
NSA 290 gn is good for the Long Barrel Texan .45
NSA 240 gn is best for Short barrel Texan .45
Hope that helps

...from what I have read here getting your scope and mounts sorted out would be the first order of business...
...without a comfortable and consistent sight picture you are not going to be able to shoot well...
...chasing the point of impact around with a bogus scope that will not hold zero is not much fun neither...
...this is one of the things that separate expensive scopes from "bargains"...

When I started I used to have Benjamin Springers n they were devastating on such a cheap scope...a texan would have the same abrupt movements of a powerful Springer..buy a long picatiny rail adapter..fx adjustable rings picatiny..and please a decent better scope..right now decent scopes start at $260 ... there is no point in trying to shoot a 1,000 rifle with a $60 dollar scope...as soon I upgraded the scope the Springer's were exceptionally accurate..for what they were..

I have heard the same thing. The twist rate needs to match your barrel. Give a lighter weight slug a try.
I would also say to get a decent scope. Cheaper scopes often don’t have much adjustment capacity.

I've tried:
Mr hollowpoint 300, 333, 350
NSA 240, 290, 302 BT
Next trip out, I plan to try the NSA 196s i use in my 909s.
Out of all of those, the 302BTs did the best with a 2" group at 50 yards (but about a 14" group at 100 yards...walking down the sheet), I know I've got to be missing something on mine. I have a 909s I can get 3 touching holes at 50 yards with.
I did have initial scope problems, my picatinny to dovetail wasn't holding. I've switched to a one piece lockdown mount i used to have on a springer, holding an athlon argos btr 6-24 ffp, so i feel like i have halfway decent glass on it.
Any more suggestions?

Try diffrent holds.
Maybe its hold sensitive.
Forget about 100 yards until you have 30 yards perfected.Then move to 50 yards.
Perfect that weather its ammo,hold sensitive or scope

I hunt with a Texan .457 Carbine CF. One thing I have found is that if I loosen up my grip, almost like an artillery hold, that my groups tighten up. With the amount of air it's pushing, and the weight of those slugs, a tight grip will result in a deflection of the barrel end in the time it takes the slug to leave the barrel. Try loosening your front grip and don't hold the stock tight in to your shoulder, but allow it to move a little in a parallel line to the barrel.
If you have a CF, and are shooting light slugs like that 240, you will want to not fill it up all the way. Stop at about 3200, or your first shot will be a lot slower than the next because there is not enough back pressure to keep the valve open long enough at the high pressure.
You can practice with a tank tethered to it, but that may work against you when hunting. You wont have that in the field, and you wont get used to the fact that the third shot will hit lower than the first or second. Remember that you are dumping up to 450 PSI with each shot. With a fill to 3400, shooting a 300 grain Mr Hollowpoint, my first shot at 50 yards is about dead on (because that shot is what it is zeroed to), my second shot is a half inch high, and my third shot is about an inch and a quarter low. I'm sighted in at 50, and so far know what to expect at 40 and 60 so I can compensate, shot by shot, in the field.
Unfortunately, that required practicing with the expensive slugs I use for hunting. I have a box of cheap 250 grain, but they shoot high to my zero and do not behave the same way as the 300 grain hollowpoints from shot to shot. So I practice with my hunting slugs so I know what to expect in the field.

I might be running into hold issues. My 909s likes to be firmly pressed to the shoulder, I've been doing the same with the texan.
thanks guys!

I have the .457 long barrel and 2 other Airforce guns. For sum reason Airforce guns tend to have scope rails that require that the scope be shimmed under the rear mount. You could also go with no-limit FX scope rings. I use a laser bore sighter to get close to the bull. This will show you if you need to raise the rear of the scope without shooting and wondering where the gun is hitting. My .457 likes to be filled to red line max on gun gauge and I get 8-10 shots before significant drop off occurs. I am shooting NSA 265gr. hollow points and the gun likes these. I am getting 1-2" groups at 70 yards. It hits pretty consistently at 100 yards but drops a few inches at that range.

Thanks everyone!!!! You’re all awesome and I appreciate the help........ Good thing I bought a cheap scope from Amazon, but it did happen to be my scope I had prior that was throwing me off. Finally got my SCBA tank all figured out and hooked up so I was able to figure out that my gun likes 2800 psi, and after trying the scope riser for my original Center Point scope i got, it was still not accurate, so I left the riser on, put the new cheapo scope on and it was a little better but still very low, so I took the riser off and BANG...... I was finally able to see the difference. Now I have low profile rings on currently and I am going to get some medium and high rings and try those out bc I sure don’t like having to cock my neck so far, but in the meantime by the time range day came to an end after 5 hrs I was hitting 8” plates at 150 yards. I zeroed at 75 yards since I like long shooting and then I just used my reticle lines for closer and further yardage and I’ll tell ya, this gun is everything I was hoping it would be. And it’s deadly accurate once you figure it out........ Now I’m going to get a nice Vortex scope, maybe an infrared setup as well for my trips to Texas!! But what I REALLY need now is to know if the African Air Ordinance modifications are worth getting for upping my power for more superior kill shots on big game? I’m worried that with the 4500 psi bottle that my SCBA tank will be useless considering it is only a 4500 psi tank...... and also, what about there other upgrades like the carrier tube and medium spring? Although I KNOW this gun is deadly at 50+ yards, I bought this gun to hunt and I want stopping and dropping power! Since I now have my SCBA tank And a shop to fill it 10 minutes away I no longer have use for my Benjamin Traveler Compressor. So if anyone is interested in it I’ve only had it 2.5 months and used it maybe 4 times...... Pm me with offers or interests in it. Otherwise any help on upping the power on my gun is ALWAYS appreciated. Thanks everyone again!!

I ran into the low scope problem as well, and had to cock my head to the side to see through the scope. Annoying. I had to use both a pic rail riser and Leupold tall rings to get it up to where it fell in line with my eye when I shouldered it.
LOL - if you had said "Center Point" in the original post, we could have told you the problem right off. Worst mistake I ever made, and I got rid of mine on day two. It would hold aim for maybe a dozen shots.
Might want to keep that little compressor. You never know when it will come in handy for topping off when the big tank is low on a Sunday, at the fill shop, or whatever. I have a big tank and a compressor on the way, but I am going to keep my little box compressor anyway and keep it in the trunk in case I run off hunting or something and forget my tank.

Thanks for the help. But nah I don’t need the compressor anymore. I hate 2 SCBA tanks now. I’ll take $420 shipped for it.
