Not sure the comparison of barrel twist between the Texan and Extreme. The Extremes are very slow twist. I think my .408 is 1:22. I am sure twist rate will have tons to do on stability at longer distances. Maybe Bob or someone else can compare twist rates on these two guns.The Texan is 1:20 twist. I did some testing on lighter bullets which were ok at short distance (50 yards) but not at 100 yards.I swaged 370, 320 and 250 grain bullets all the same exact design but shorter to make lighter. The heavier/longer bullets did better in every design.Nick,I'm no expert of bullet stability, they either are or aren't stable at longer distances. I'm certain the twist rate is important for a bullet, but not so sure of it's importance with round balls. I've only tested round balls out to 50 yards, but they look very promising, but so did a lot of bullets which I actually saw corkscrewing as they went further out beyond 50 yards. I've read that they can tumble at longer distances, but I see corkscrewing, I'm not imagining it.I was hoping round balls didn't suffer from the same gyroscopic effects that are hindering the lighter bullets. I guess I'll have to wait until the weekend to find out.Here's hoping Ha Ha

Sorry supertech 77, I attached my post to your quote , chalk it up to old *art syndrome LOL.
So the tex turns out not too interesting anymore, once you see what's inside. Nothing fancy, just another af rifle with a bigger valve. A bit of a bummer, was hoping that they had a pressure assisted valve and light hammer, just a big valve, heavy spring and heavy hammer, nothing to write home about. Marko

Marko oh and a lot of power,ya forgot that.
The Hornaday Round Balls still made good groups at 100 yards when I tested at that range... about 4" groups of 5 shots, untethered, with a 2500PSI fill.I was impressed, they were better than many of the bullets I've tested.
We'll see about it when the 45 gets out, but it's still butt ugly. And what comes to the tex, the accuracy reports I'm seeing are poor at best. Nothing to do with power if you can't hit a broadside of a barn with it. And rkr, I have my own valve already at proto stage for my .357, and drawings for the savage and fury valve. Both are assisted valves, try and open 22mm valve with a hammer alone... Marko
mjp, don't know how small the barns your shooting at are, lol, don't know where you get your accuracy reports , but if one can hit a 2 inch square at 97 yards time and time again , with over 505 fpe out of the muzzle ,with a 457/385 and a 460/330 then i would be hunter content ,these guns were not made for shooting paper targets ,they were made to knock the heck out of what ever they hit while hunting , and leave a wound channel most any animal could not survive ,so if you want to put down the a/f Texan,if you have actually shot one for anytime,then that's your right, but as for me and most owners whom shoot there's as often as possible,because its fun, its powerful, and they get better with it,and i think mine is beautiful as for the slayer, top quality ,very accurate and twice as much as a Texan,i will own one of them soon too,not in 45 cal,maybe 357,but thanks for your input.
