yea thats pretty small.. easy to open , but too small.

Then you have PBBA, but the energy numbers I've seen are rather low. Go with the Slayer if you can handle a bullpup and can wait even longer.If you want Slayer-like performance in .357 give Brian Thurman a call and have him build you one of his Taurus's. It's not an AAA gun, but you can get it much quicker and the gun itself is more accurate than most are capable of shooting a big bore bullpup. The Bulldog stocks are ugly, but Brian has a great performing package. If you don't mind a long gun and don't care about looks get a Texan!!! Mike what was the factory porting on the 457??

I'm trying to let the looks of the Texan .457ss with a carbon fiber tank grow on me. Partly because the cost is pretty close to what I got for me 22.250 and then I could save for a bigger tank altho I would still like to know How many fills I could expect from my 90 cu. in. carbon fiber tank. So if I have to get a bigger tank and then maybe a compressor It'll be a bit longer before I can hunt deer in Indiana with a big bore air gun.
Yeah I think you're right but other than getting it sighted in I'll only shoot it during deer season and then hopefully One shot or two. The rest of the year it'll probably just sit in the safe just like my slug gun and muzzle loader.

Mike what was the factory porting on the 457??As delivered, .375 exhaust to barrel. Throat was .340 with a .160 stem. I opened the throat up to .375 by removing the OEM delrin seat and steel poppet combo and created a seat in the aluminum valve body, then added a peek poppet. After lightening the hammer it made more power and with a much tighter ES across the first 3 shots. Max power was just under 570fpe. It would do a 3 shot string of 254gr 970, 946, 900fps. Not bad for a 26"barrel. I look forward to seeing what the 32" barrel will do....
Manny, really you think that would work for me? I have two pumps a Hill and a $21.00 Chinese one. My buddy isn't always real reliable on getting my 90 cu. in. tank filled so I've been filling my .25 Marauder with the hand pumps mostly. It's really not that bad I never let it get so low that it's a real job. Sometimes tho I do like to take the Marauder out and shoot it a bit just for fun, then a compressor might be pretty handy.

Mike, that's good advice getting the air source ready first with a compressor and large tank(s). I would even recommend dual 88 cu. ft. CF tanks for big bore. The Texan fills to 3600 psi, so all you'll be able to use from the tank is from 4500 psi down to 3600 psi before the tank needs topping off again. Good luck getting a tank filled to exactly 4500 psi to begin with and keeping it there after cool down from filling, so really less than that. You'll get plenty of shots for a hunting day for deer, but for plinking/testing it will be a short session before needing to refill. With a 90 cu. in. tank you may get one shot off, but it may not be in the sweet spot. I'm just guessing here though. There are online calculators you can use to get a real ballpark figure. You have to consider other factors within that result, like the loss of air from disconnecting the hose.Now, when I am at the range with my .357 Slayer and one 88 cu. ft. tank, once the tank hits 3800 psi I leave the tank valve open since the gun fills to 3800. I then can shoot quite a number of shots from the large tank while my 5' whip hose is connected to the Slayer. If that's the way you want to shoot the Texan is from a bench, you'll be okay for a good many shots doing it this way. I do get two hours of shooting in at the range (minus the cold line times) with one 88 cu. ft. tank doing this. The Slayer uses up ~ 150 psi per shot. The Texan would use more.
Mike, I use to get $5 tank top offs at a scuba shop also up until they needed to have their compressor rebuilt. After that came new rules where they would only fill up to what their reserve tanks had pressure wise. No more running the compressor for us air gunners to get 4500 psi anymore, plus a higher fill price at that. I guess their compressor rebuild cost set them back a good bit. This is when a compressor for me became a must. There's nothing like having your own air source, and casting your own projectiles.
