Welcome to my airgun and antique firearm blog.
I post photo's of my personal collection, and a myriad of pic's and information on Air pistols, air Rifles, and pre-1898 Antique Black Powder Guns... and occasionally I will post images of various confiscated, improvised, modified howmemade firearms from around the world.
The .177cal/4.5mm H&N Prometheus shoots very well in my 70 year old Benjamin model 317 pneumatic air rifle!
Crosman's lead free .22cal/5.5mm Monster!
I love this AirGun ammo!
I feed it to my Crosman 2240, 1322's, Diana Chaser co2 rifle and my Beeman P1 Magnum spring piston air pistol!
The 8.5 grain penetrators are devastating when shot by Magnum power AirGuns.
The .177cal/4.5mm "fast flight" 5.4 grain penetrators from Crosman are the perfect length for the Crosman's 357 Co2 revolver, and any breach loading or break barrel type of AirGun.
Trevor Adams reviewed the original "Prometheus" ammo a couple of decades ago:
Thanks to Mr.Marvin "The AirGun Guy", I will have this vintage multi-pump pneumatic .177 caliber pellet single shot bolt-action air rifle sometime next week 😎
UPDATE: my new vintage .177 caliber Benjamin model 317 arrived yesterday!
It shoots well, and looks great, but might shoot better with a good cleaning & polishing as well as some pellgun oil treatment for the pump seals and external moving parts.
Northwest AirGuns demonstration with a cutout Benjamin model 312, which is the .22 caliber variant of the 317, or vice versa:
In another Northwest AirGuns video, a model 312 air rifle is disassembled. The 312 is the .22 caliber pellet variant, the 310 is the "BB" caliber model and the 317, which I have, is the .177 caliber pellet model:
"Trev's AirGun scrapbook" had jpeg's of the original user manuals for these old Pump pellet & BB rifles, as well as other vintage advertisements & photographs.
Below, is a near mint condition Benjamin 317 with most or all of the black nickel finish on the brass parts:

Baker Airguns, in Ohio, is a super resource for vintage AirGun parts, like this Benjamin peep sight, and seal & pump repare kits: Baker Airguns
I have been cleaning up and shooting this Benjamin 317 for a few weeks now and it functioning as well as it did over 60 years ago when it was new!
Since I am working on the air rifle indoors, I am only using lead free ammo, to avoid any trouble with lead.
This has given me a chance to try out the various lead free "sabot" style AirGun pellets that I have.
I have found that lead free H&N excite Prometheus pellets and crosman PowerShot penetrators perform marvelously with this pneumatic air rifle.
The 6 grain H&N Prometheus pellets are tight fitting in the breach, and the crosman 5.4 grain & 8.5 grain penetrators both have a loose fit.
I have ordered a thousand rounds of H&N Apollo pellets, which are the heavier version of the Prometheus pellets.
The 6 grain H&N Prometheus pellets look cool with their black polymer skirts:
I have spent quite a bit of time cleaning the exterior of the air rifle with oil, rags & q-tips and the AirGun is looking Sharp!
The Benjamin 317 next to a Sheridan "Cowboy" BB gun!
