If the red wolf regulator was not working at all so it was unregulated it wouldn't be too bad.

I expect my under $500 SPA guns to be under 20 ES and under 5 std dev.

sounds like my notos under 15es and 1-3std dev

Nice looking example! They are great guns and built to last. The buffer is definitely a weak point, but you shouldn't have to replace the piston ring. Here's comparison pics of a new one and one out of an old work horse club gun FWB300s. No visible or measurable wear. The buffer had crumbled on the same gun.

I think in much of the States, convicted criminals are prohibited from owning powderburning firearms. Given the sheer volume of humanity that gets convicted of something in the States, that's a significant market of people looking for "gun like things" that can't own powderburners. So high-powered airguns it is.

I shoot BP. There is one major advantage of air. Fouling. Oh and Shot preparation And noise, and cost per shot. And the giant cloud of sulfury goodness.

Although, maybe I should take the whitworth or martini Henry pesting.

Head-to-Head Setup​

Spec	Texan .308 (Airgun)	CVA Paramount Pro .45 Cal (BP)
Projectile	150gr SFBT (pure lead)	280gr PowerBelt ELR
Muzzle Velocity	~1042 fps	~2320 fps
Ballistic Coefficient	~0.200	~0.333–0.452
Muzzle Energy	~361 ft-lbs	~1600–1700 ft-lbs

The Paramount Pro is arguably the most advanced production BP rifle today2—a true long-range beast with high-BC bullets and super-magnum charges.

Energy Retention @ 700–800 Yards​

Range (yds)	Texan .308 Energy	Paramount Pro Energy
700	~95 ft-lbs	~400–450 ft-lbs
800	~70–75 ft-lbs	~300–350 ft-lbs

• Black powder wins on raw energy, no question.
• But your .308 still holds ethical precision for small-to-medium game at 800 yards.

Drop & Wind Drift (Zero @100 yds, 10mph crosswind)​

Range (yds)	Texan Drop	BP Drop	Texan Drift	BP Drift
700	~250 in	~300–320 in	~55 in	~65–70 in
800	~340 in	~400–450 in	~70 in	~85–90 in

• Your Texan’s flatter trajectory and tighter wind profile give it a serious edge in precision.
• BP’s heavier slug fights wind better than lighter BP loads, but still drifts more than your .308.

Time of Flight​

Range (yds)	Texan TOF	BP TOF
800	~1.6 sec	~1.3–1.4 sec

BP gets there faster, but the Texan’s predictable flight path and ZULUS integration make it easier to correct mid-flight.

Tactical Takeaway​

• Paramount Pro dominates in energy, making it ideal for elk or large game at distance.
• Your Texan .308 wins on stealth, control, and precision—especially for coyotes, hogs, or pest control.
• At 700–800 yards, the Texan isn’t just holding its own—it’s outperforming BP in ethical hit probability.

First you have to know the restraints of a BP rifle even though they produce a great deal of fpe:
1. Inconsistent Burn Characteristics

• Black powder has a non-progressive burn—it ignites fast and dumps energy early.
• This leads to pressure spikes that vary with humidity, grain size, and even how tightly the projectile is seated.

2. Fouling and Residue

• Every shot leaves corrosive residue in the bore, which affects velocity and accuracy unless cleaned between shots.
• Fouling buildup changes barrel harmonics and projectile seating depth—bad news for consistency.

3. Ignition Variability

• Percussion caps and flintlocks introduce delay and variability in ignition timing.
• Even modern inline BP rifles can suffer from hang fires or misfires, especially with loose powder.

4. Barrel Pressure Drop

• Black powder pressure drops rapidly down the bore, especially in longer barrels.
• This limits velocity and makes it harder to maintain a flat trajectory past 600–700 yards.

5. Projectile Design Limitations

• Most BP rifles use heavier, round-nosed bullets with lower ballistic coefficients.
• Even advanced BP rifles like the CVA Paramount Pro use high-BC bullets, but they still fight gravity and wind drift harder than your airgun’s boat tail slugs.

Tactical Summary​

Even the best BP rifles—like the .45 cal Paramount Pro—can reach 800+ yards, but they struggle with:

• Trajectory arc (think rainbow vs laser beam)
• Wind drift (especially with lighter sabots)
• Shot-to-shot consistency (due to fouling, ignition, and powder variability)

I raise you the .451 whitworth.

At least you have some to shoot. This place is beyond loaded with a never ending supply of them. I am in the high hundreds and hundreds. And the size of these things is unbelievable. There’s so much grain and food everywhere for them. So lucky to have this spot.

Yes you are… keep at them, good shooting….

I've sent you two new take off barrels from new rifles. The reason there's a spacer mid way down the shroud is to keep them straight. No, not all are going to roll true on a precision ground table. Yes I'll send you a refund. Absolutely. I'm so sorry I even tried to help you. You ruined a barrel, umarex wouldn't help you. I've spent several hours trying. I understand the frustration on the first one. I should have caught that. You're running bore scopes and rolling barrels but have yet to shoot it to see if it's accurate. If I spent that much time trying to find a reason it's bad, I'd have missed out on some of the best guns I have. I'll post a picture showing the refund blurring out you're info. I've learned my lesson trying to help people.

I’m sure there are thousands of bb’s and pellets at the bottom of the pond where I grew up. A million? Not likely but quite a few thousand.

Good girl! Morgan is a sweet looking dog, she looks happy with the kill. Her brown eyes seem like she’s offering you some of the bounty…

The hidden screw is at 18 visible sticking out the top of that assembly.



There is no need to depressurize to remove the breech and barrel assembly. There are set screws underside of the breech that lock the barrel in position.

Probably the best thing to do is to learn not to try and shoot multiple pellets out of the poor thing. The rifle may clear a double feed, a triple or more, probably not.

I picked up a Benjamin 312 today. I had been looking around for one a found this at my favorite airgun smith’s shop. Couldn’t leave it behind. And yes that’s the messiest room in the house. My wife refuses to go there.

I have the 40 cal CVA I use a 225-gr bullet, 600 yards is as far as I would push it and I will tell ya, I would take my Texan all day long, No smoke, no measuring, hardly any recoil, cheaper ammo.

The string only included to "good" shots, nothing off the reg as it were, as the RW technically is not regulated.

If it's like a Yong Heng compressor, most likely the high side piston ring ( carbon ring) is worn causing blow by. It's does not like to run above 65 deg C. I don't use the recirculating pump anymore, I run a straight hose from the faucet and just let it drain to the lawn.

I'm using a 40 gal tote filled with 20 gal of distilled water , and some Royal purple purple Ice , and antifreeze in that water. I'm using Seco Lube 500 oil , and watch the temp Closely. Even when I filled my 6.8L it never got hotter than 122 °F. I would have thought that it would have lasted more than 4 months after all it is rated to fill a 6.8L I'll pull it apart , and inspect it though.
What oil do you use in the YH.

I put a scope setup list together.

Rifle scope sighting adjustment, POA = point of aim & POI = point of impact.

• 1. Start with the rifle/scope securely mounted on a table/bench where it will remain stationary with NO movement.
• 2. Use a paper target that is set out at 25 to 100 yards from rifle/scope.
• 3. Fire a 3 shot group without moving rifle/scope using the same (POA) for each shot.
• 4. Look through the scope and locate the center of this 3 shot group on the target (POI) and make sure that the rifle/scope is NOT moved.
• 5. WITHOUT moving rifle/scope, adjust crosshairs on the scope to the center of this 3 shot group. The scope crosshairs will now be pointing at the center of the 3 shot group fired by this rifle/scope combo at this sight in range
• 6. Repeat steps 3, 4, & 5 to confirm or fine tune the accuracy of the scope adjustment.

Also, do yourself a favor and notice how many seconds it takes for each shot to refresh. You might be in for a big surprise!

I do. I use it to hold my cocktail pick & lolipop targets on the range. Eventually it wears out but since I got a second use out of it I have no issue throwing it away, and I've got plenty of replacements.

OUTSTANDING!!! Repurposing at it's best!!!

@thammer are you not going to stand behind your word as you pride yourself on? Please let us all know so we know how to move forward. I need my money refunded. Period. I’ll ship the defective barrels back to you. Stand behind your word that many come to your defense over.

Mike, 30’s are difficult for us to score in 50 matches due to the nasty holes they make. When we have a questionable hole we will push the paper upward from the back side then carefully insert the plug from the font. We have had very good success doing it that way. Regardless, great card. Now go get that 250!

I don't hunt coyotes currently but I like to test my hunting airguns for penetration in wet magazines before hunting with them. I want to be sure I am getting enough penetration. I test at a representative distance for my hunting. Tests with several slug candidates would give you expansion and penetration information.
