The "Rifleman's Rifle" has been reborn as the Winchester 70 PCP Air Rifle.

Inspired by the bolt-action Winchester Model 70, this sidelever PCP follows its predecessor as a precharged pneumatic big bore airgun.  Powered by a 320cc air reservoir and with a fill pressure of 230 BAR (3,335 psi) the Model 70 will have no trouble slinging its rounds downrange.  With 6 full powered shots in .35 and five in .45, you can expect speeds exceeding 800 and 700 fps respectively blasted with a thunderous release of compressed air.  While the gun has no open sights, an 11mm Dovetail rail is ready and waiting for your own optics choice.

The cylinder rests snugly within a masterfully crafted beechwood stock, with traditional checkering on the grip and forend to provide a comfortable and stable hold. A hunter style safety keeps the Model 70 muzzled until ready to fire and a 2-stage adjustable trigger can be set to your preferred trigger pull.

The Model 70 PCP proves that Winchester is ready to enter the world of PCP hunting--are you?

Things I liked:

The quality is incredible too on this rifle its made like the 30-06 or .223 Winchester. I traded the Bulldog .357 and that was a plastic gun and felt cheap, this model looks beautiful too but I haven't fired it yet but put a nice scope on it and have to sight it too.

Things I would have changed:

With a higher grain pellet is should have enough power to take down a whitetail or any hog. I didnt know they made a .45 but with a higher grain pellet your going to get stopping power.

What others should know:

Its allot of work pumping this up so a tank would be good too if you want to spend all day shooting with it your going to need it. Im 6 foot 4 300 lbs and about as strong as big and its allot of work. Also make sure if your using the adapter too put the plastic piece that comes with it or its not going to pump up with or without a tank.

Things I liked:

This is a beautiful air rifle, no doubt - first thing that strikes you out of the box or case. Also really happy I ordered the $20-for-$20 shoot test that PyramyAir.com does for you along with the scope mount - gives more confidence and they precharge the rifle - it came with 150 bar in it for storage until you're ready to take it to the range, then you know it will take 220 bar per the shoot test printout they give you. Mine was done with 166 grain pellets and you receive a printout of about 20 shots FPS.

Things I would have changed:

The manual from Gamo needs improvement. Missing information on how to load and unload the rotary magazine into and out of the air rifle - it's easy but still needed info a proper manual should have. But you can find great video's on the reseller and youtube sites and pay close attention to some of them to learn how this all works. I noticed some people reviews did not realize an empty air rifle needs the lever pulled back to fill the rifle, too bad the manual is missing that info too. But you can get past those things by researching online. And I would like to see them get extra rotary magazines in stock - this air rifle can shoot about 2-3 magazines worth before having to refill, so having them sitting there waiting rather than constantly refilling one magazine, would be great. They really should sell this rifle with an extra one anyway.

What others should know:

This rifle's average maximum FPE (foot-pound energy) is indeed 199-200 which depends on the air-fill and the triggered air-blast which can naturally vary a little, and depending on the grain weight of your selected pellets (it can take 137, 150, 166, 180, 200 per various sources) will result in the FPS (feet-per-second) muzzle velocity of the pellet. FPE = 0.00000222 x GRAINS x FPS x FPS (yes that equation is accurate) if you want to do your own calculations. There was also one video on youtube that shows you how to increase the average maximum FPE a little - maybe 10% better which results in a little faster FPS. (Too bad that is also missing from the manual - Gamo please do better on the manual.) But as I keep looking out there at other air rifles, this Winchester model 70 .45 caliber continues to be about the best in FPE, in fact approaching some of the .45 caliber firearms FPE. Do your own calculations. If you are into PCP air rifles, you will want this one!

Things I liked:

Beautiful rifle overall and feels great holding it. If the local ranges were open, I could try it out.

Things I would have changed:

Please sell extra accessory magazines for this rifle! It can do 2 or 3 magazines worth before refilling the air in the rifle, so you can see how that would be highly useful to us. I keep checking back with GamoUSA but there's a delay on them getting the products in.

What others should know:

The manual is rather terrible. It fails to show you how to load and unload the magazine in the rifle for one, and is poor at details on filling it with air. Recommend you go to youtube and search Winchester model 70 air rifle, and watch all the videos you can, in which you can learn how to do some of that from those who have done it.

    With the moderator already installed from the factory, can it be removed and upgraded?

      What size ammo does the 45cal fit bought the 200gr hallow points and it doesn't fit the clip...

    • randy from USA asked:

      Does Pyramyd add the moderator or is this a factory option now? On Winchesters site they don't have the mod.

      • Mark from USA answered:

        The gun comes from the factory with the moderator installed.
