How does crosman make their barrels?

"Unless I am wrong in assuming that choked barrels shoot pellets better than unchoked?"

Those chopped and re-crowned pistol barrels above are definitely not choked.

"i have dreamed of some machine or press that would – in a precise way – press the end of the muzzle while rolling 7/16" crosman barrels."

If I'm remembering correctly, I think Pomona Airguns re-chokes barrels. Also think I've heard of someone else that can, but don't recall who.

Gasman,

i stand corrected thank you

On your unchoked barrels, are they pellet picky?
 
Seems like a common misconception that choked barrels shoot better than unchoked . In my testing, good barrels are good barrels. I'm not sure if it's true that they are more forgiving of pellet quality, but that has also been disseminated. I've just not cared to try to prove or disprove it.

I've purchased 18 LW barrels in 177 in the last year and a half that were a mix of choked and unchoked for personal use. All that I've used so far were pretty good but the best, most forgiving of pellet choice , were the unchoked. I've prepped 3 of those now that are competitive with just about anything. One is in use on my Tsar and another on a friend's Tsar and though I've not fared really well with it yet, they both shoot phenomenal. 

Like AirnGasMan, I have a god selection of older Crosmans and they shoot pretty well with current pellets and are not choked. Consider that I bought a spare fitted and finished and blued barrel for my 1400 for $9 before Crosman quit supporting older models..... and they shoot pretty well. Btw, that was the going price... not a sale or closeout .

Anyway .. just my $.02.

.02 duly noted thank you. Going to buy an unchoked LW next
 
If the pellet fits the barrel correctly then a choke is worthless. The choked barrels from my understanding started to help deal with less than consistent pellet sizes. I have a BSA S10 that I cut down from 18" to 10". That barrel didnt have a choke when it was 18" but still shot extremely accurate and after cutting it to 10" and removing any chance of a tighter spot at the muzzle its still extremely accurate. 

I would like to know what tricks crosman has come up with. Barrel making has been around a long time and I dont think crosman has learned anything to do that world record setting barrel manufacturers dont already know and use. With that said I hope crosman does make competitive barrels but I doubt the "new tricks".

LDP,

thanks for the info. Perhaps if crosman were to hire a barrel maker with a passion for mechanical engineering(vice versa), they could possibly come up with some “new tricks”
 
"Gasman, On your unchoked barrels, are they pellet picky?"

To tell the truth LA, I wouldn't know.

I abandoned Crosman pellets long ago after they lived down to my 1988 prediction (in The Manic Compressive) that, "Crosman would do well to do well... meaning quality must remain high if you expect to remain on top!" Mind you, this was after I had already abandoned RWS Superdomes, Eley Wasps, and Marksman Field Target Specials once their quality devolved from beautiful to hideous.

When JSBs came along and blew them all out of the water, I dreaded the thought they would also similarly devolve; but it's been many years that they've earned, and continue to deserve, my confidence. By matching the JSB pellet (weight) to the power of the gun, almost invariably I get extremely gratifying accuracy results. That usually being the first (and second) JSB I test in any given gun, I don't bother testing other pellet brands or JSB weights ill-suited to the guns purpose. For instance, lighter-weight JSBs for moderately-powered guns, medium weight for medium-power guns, heavies for magnums, and super-heavies for maxi-blasters.

Pretty simple stuff really... that simplified my pellet inventories considerably since I shoot .177, .22 and .25 calibers. Mind you, I'm a simple man (as much as possible in this day and age) that believes whole-heartedly in the adage, "Simplicity is the hallmark of good design". That adage serves me very well, so I'm not about to abandon it anytime soon.

Point is, I can only speculate that my unchoked barrels are not pellet picky. But I can confidently state that they are not JSB pellet picky. 


 
.... no....many good airgun makers dont choke barrels , but in my experience the choked barrels ( like the .25 cal green mtn barrels crosman uses for mrod - shooting the .25 cal benjamin pellets) make the gun shoot many other pellets better . the choked barrels are used sometimes to create more back pressure during the shot cycle of springers. it seems if crosman was going to really do their barrels better , we wouldnt be seeing the green mtn barrels .... but who knows ? crosman was a 60 million dollar / year corporation , and that was ten years ago (looks like 118M/yr now) .... - paul.
 
Ranedouglas,

Don't want to disappoint you, but for the last 1 1/2 years or so, Crosman has been making their own .25 caliber barrels for the Marauder. They no longer use Green Mountain Barrels. 

For the others that inquired on this post, most all of their PCP barrels are choked, most pistol offerings are not choked

How? ?

Are the new barrels ( say in .22) different? Oh yes. Different rifling and much tighter bore at least on the maximus when it came out. Mine was a true "golden barrel" (shame about the trigger but) and I've personally seem a couple of other shoot as well. The change was well over a year ago and very much for the better.

By the looks of your achievements I’ll take your word on JSB being the best pellet

Looking like they do have a few tricks up their sleeve
 
Actually, I am a collector and a shooter. Was also a vendor of Theoben and Whiscombe rifles for 15 years, before both brands became unavailable.

As Ron has said, the button rifled Crosman barrels of the 50s and 60s and early 70s were very good. This is especially true of the CMP 160s which had some really stellar barrels. Of the 20 or so vintage Crosmans in my collection, all have great barrels. Not so with the current offerings. Crosman has changed ownership several time in the last 30 years with the trend being toward a price driven, box store mentality and declining QC. An example of this devolution in quality can be found in CP pellets. When Premiers first entered the market in 1990, each pellet design was made on a single, perfect die and each brown box was hand inspected and packed. For us serious FT shooters, these perfectly uniform and accurate pellets were a dream come true. The same pellet made on other dies were marketed in tins at about a third the price and were not called "Premiers". However, as everyone knows, today's "Premiers" are a crap shoot. Boxes and tins contain damaged, or peewee, or partial, or dirty pellets - or even just a blob of lead. The same is true of the barrels. They are a crap shoot - rough bores, missing crowns or just plain lack of QC.

These barrel problems became generally evident when the M rod first came out and masses of rifles were returned because they wouldn't group past 25 yds. Just as poor quality pellets will usually produce acceptable groups out to 25 yds, so will low quality barrels. The difference really shows up at higher velocities and longer distances. Crosman addressed this issue by offering low tier Walther barrels to increase the chance of getting a good one. If a manufacturer has to offer barrels to replace its own with those from a different maker, there is a problem.

Please understand, I am not a Crosman basher and understand that it is not economical to put a $50 barrel on a $1-200 rifle. However, the fact that in the past they made, in-house, barrels that were second to none in the airgun world - should mean that they can do so again. I am rooting for them and hope they will.

Respectfully submitted - S

Quality control doesn’t come cheap. Crosman sells low cost airguns made in high volumes. During ownership changes, the new owners want nothing more than to skim as much cash from the company as they can. They may buy lesser quality rifling buttons and use them longer than they should. Quality rejects may sneak by easier too. See where I’m going with this? Hopefully the current owners are buying better tools and maintaining more consistent tolerances. Those are the only “tricks” I can think of.
