Just picked one up for 20 bucks and was just wondering if it is powerful enough for grouse.. ran the serial numbers and it appears to be made in Nov of 1967...it holds air and is black painted over brass and the barrel is bronze..I think...the cal is .20...5mm...will try to find some pellets for it out my way...in between the .177.......22...actually in real nice shape...bit on the heavy side around 6 lbs...with a walnut stock, just wonder also what pellet would be good to use... Thanks

Sheridan still sells the Blue Streak. A new one will run you $275.00 plus taxes and IMHO they are nowhere near as nice as the old ones. They are a 'PAL-rated' air rifle BTW.
Sheridan originally made them for serious pest control and small-game hunting. Anything up to jackrabbits should be readily killable with it at ranges under 50m. I read at least one credible report of someone killing a bobcat with one; he was in a tree stand and when the cat walked right under him, he shot it in the back of the head/neck. Not a recommended use, of course, but it does give a good idea of the potential power of the combination of that rifle and the .20 'ashcan' pellets.
Incidentally, Sheridan still makes the heavy pellets for its .20 calibre rifles.
If you are having a tough time finding pellets and accessories locally, try D&L Airguns (
www.dlairgun.com). They are actually based in BC. They carry Benjamin/Sheridan airguns and accessories among many other brands. I have bought stuff from them before and can highly recommend them as knowledgeable and helpful airgun dealers.
Did I mention that I'm as jealous as hell that you managed to score a vintage working Blue Streak - with the accessory scope mount yet - for less than the normal cost of the scope mount alone?

Enjoy it. Once you get it sighted in with your preferred pellets at your preferred number of pumps, no grouse will be safe from you.
