Texan

[rickjoe11]

With that round ball being so light you MAY need to adjust your power wheel. I was getting over 1000 fps with the 143 RB with NO adjustments?
I have a question of a different subject...........Has anyone found a decent CASE for this beast yet that will comfortably fit scope and bipod. I picked up one at Cabela's and length was fine, but zipper was awfully snug around the scope. Not really wanting to spend a lot as it won't be traveling much.

[johninthecamper]

drag bag isn't a case,but same function, all wrapped up,.50 cal bmg one should be long enough

[jaraxle1zx]

Air Force still have plans on making a ldc?

I'm really thinking about getting one of these, yall seem to be having good luck with it.
And my guitar hobbie really has lightened my wallet, so this gun is looking real good for the price.

[David McAfee]

Has anyone tested the effective range of the Texan yet?

[Metnav1]

David,

I've been working on trying to find an effective bullet at 100 yards... Most bullets tested destabilize past 50 yards, and start to corkscrew.

Nielsenammo here on this forum sent me some test ammo, it was heavy ammo, but it was very accurate out to 100 yards.  I haven't tested the gun past 100 yards, but based on theorectical measurements it should easily make 150 yards, with the right bullet

[David McAfee]

Any idea what kind of punch they have at that range? I can't use mine for hunting in TN (yet), but I'm curious as to what kind of game you could take at 100 yards.

I'm looking forward to seeing what you come up with for that 150 yard bullet.

[Metnav1]

David,

The only bullet I've tested that was likely to be good at 150 yards was a 340 gn from nielsenammo (on this forum)

It Chronied at about 750 fps, at 425 ftlbs, at 100 yards it should be 340 ftlbs (6" drop sighted in at 80 yards), and at 150 yards 305 ftlbs with a 36" drop.  These are the theoretical figures, but I expect they're pretty close to actual.

I use theoretical measurements to get me close when actually testing reality.  Theory is close, at least in the ball park of reality.

With 305 ftlbs still left at 150 yards, it will kill what it hits... The problem is knowing the actual drop, and allowing for the wind drift at 150 yards which in theory is about 6" for a 5 mph side wind

So, if you sight your gun for zero at 80 yards, at 150 yards there is a 36" drop, and 6" drift at 5 mph wind speed crosswind.

I test my bullet, and record the data on a small card that I carry with me when hunting... Sometimes I need it LOL

[supertech77]

I use a flambue hard case ,all fits nice and snug, with bipod, 50mm scope,light,and wasn't very expensive,

[David McAfee]

Excellent info. Thanks.

The one thing to remember compressed air will only go so far. When you reach bullets weights of over 350grs you know your yardage is going to be short. With that said it turns more toward using bowhunting ranges for game they will never compete against PBs at long distances. Reading and searching all calibers it seems that once you get past 30cal your range goings down considerably. So as long as you intend to use the weapons for 75 yds or less you are good past that and will it will take alot of during to get it done.

[nielsenammo]

For me the problem with range in a pellet, air rifle, etc is the speed they fly. We can accurately shoot 200 yards so if bench rest we can set the gun up for it. I am setting my Texan up for some long range testing. We will see if my skills will be of a level for meaningful testing.

However, for hunting this is not practical.  Your scope does not have enough range to cover 200 yards with a bullet flying 700-800 fps.

I did a quick chairgun calc with a 100 yard zero and a 200 yard target. The additional drop is 67 inches depending on BC and other factors. These are lobbying in like a rainbow.  Trying to make this kind of an adjustment in the field and take a shot on game does not seem likely to me.

Using the factors in chairgun, 175 yard target drop is about 44 inches from a 100 yard zero. That is 2 feet with a 25 yard estimation error at 200 yards. Same factors, 10 yard error at 200 yards makes a 10 inch difference in drop. This based on 750 fps.

900 fps with all factors the same factors the 67 inches goes to 47 inches. Compared to a fast powder burner at 3000 fps the drop is around 4 inches compared to 67 from 100 to 200 yards.

Did not mean to make so long. Trying to show with slow moving pellets there is a limit to range for field use. It is not due to accuracy but to extreme drop and importance of range estimation and limits of a scope.

  though i too believe  that 75 yards or less is the best and most humane  kill zone with air guns with power of the Texan and higher, if that is as good as you can shoot your big bore air gun comfortably ' than yes that is the best range for ones that don't feel comfortable passed that,if you have a big bore air gun that is putting out 350+ fpe at 150 yards, and you can keep 5 shots on your test at that range inside of 3 inches time and time again,,then i see no reason not to use that range,but if 1 or 2 in 5 go in the paper or test target, forget it, and stick to the range where the 5 will stay 3 inch,s or less,IMO,personally, i won't shoot at a animal past 75 yards,because i normally shoot 75 yards or less, and can easily  2 inch wide a hole at that range or less with my Texan or my 909 using 340, 385 bbt, 195 grain bullets,and if your gonna hunt with a big bore, or a bow or a crossbow, or a p/b USE A RANGE FINDER, please,and know your weapon of choice at the range your gonna shoot well,practice as often as you can,know your bullet well too, what it does at what range,under similar conditions,well any who that's my 2 cents worth .

   totally agree with what i think your saying, but what grain bullet are you using to calculate your drop?and what if you got a bullet that is right at 1k fps and less that 195 gr,the trajectory would flatten more right?i am no ballistic guru, just a question, you seem to know a lot about ballistic.s ,please explain ?

[nielsenammo]

The grain would not matter for calculating drop, it would be the the fps and BC mainly. In my Texan that fps would be around 350 grain. However in my Sam yang it would half that for the same fps, therfore the same drop (roughly).

Yes 1000 fps would give flatter trajectory,  but, you need a bullet that is accurate at range that is that short. A 200 grain bullet that is .457 is very short. Reports I have seen so far is no long range accuracy with them, even past 30 yards.

The Texan barrel with my estimation needs a fairly long bullet. However, I am going to be testing some lighter bullets to see what flys best at lighter weights.

[nielsenammo]

Give you an idea of size of a bullet when you start bringing the grains down. This is with a long nose, but all bullets in pictures are with the same base and same bullet nose.

The 210 grain bullet falls onto the nose when laid on it's side because the bullet is so short.

The bullets in the pictures are 210, 275 and 370 grains and are .454 out of the die.

I just made them up real quick to give an idea of lengths versus grains of same designed bullets.

Valid points for sure.  I think if you have the ability of say 150 yards and you are in a blind or somewhere you know your shot will be roughly 150 yards the gun is certainly capable of it.  The problem is many times we do not know the range we will take our shot from.

So to have an air gun set up for shooting both a 25 yard shot and a 150 yard shot is a real challenge.  There is just so much drop between the two variables.  I believe you to be accurate at both short and long ranges, but can you adjust that in the field to take a shot on game? If you can then no issue, I do not believe I have the skill set for that.

I am setting my Texan up  for long range testing and I adjusted my scope and FX rings to account for the range, and at shorter range I will put them back. FX rings allow you to raise the back mount. I can't do that in the field.

[supertech77]

i get what your saying, and how would that come to play in a 357,cal,less mass, flatter trajectory , and less grain than a 45 cal, say like the slayer ?

[nielsenammo]

From what johninthecamper has told me, the Slayer is a beast.  I believe John makes a 125 or 139 grain bullet that flys great out the Slayer. However, the same factors will still apply.

I think those bullets go about 950 fps, don't quote me, out that gun.  In another gun, like my Bulldog, they will go much slower.

Remember it is not the weight of the bullet that makes it drop, it is the speed.  Gravity is what makes it drop and it is a constant rate.  The difference is a faster bullet travels further in the time it takes gravity to pull the bullet down.  A bullet with a high BC retains it's speed longer so will have less drop.

Myth Busters did a video of firing a pistol bullet in level flight and simultaneously dropping a bullet straight down from the same height.  With their high speed cameras they showed both bullets hitting the ground at the same time.


Using Chairgun again with 950 fps (before I used my phone app and some setting may be a tiny bit different, now using computer version), .15 BC and 125 grain bullet:
100 yard zero and 200 yard target the drop is about 45 inches.
with a BC of .15 pellet is still going 790 fps and the energy is 173 ft pounds at 200 yards.

most people zero around 50 yards:
All other factors the same
200 yard target with a 50 yard zero is 63 inches of drop, (5 feet)
total drop from where you are shooting to 200 yards at 950 fps is about 88 inches.

[johninthecamper]

 I only know this, 125 gr sighted in at 20&85 yrds,is half inch hold under st 50 and about 36inches past 85 poi at 200
