I was going to suggest my favorite,the Sheridan Blue or Silver Streak but they get noisy at max pressure. 75 yards is stretching it a little for .177 pellets. I’d go pcp in .25 cal.
I have several boxes of originalSheridans plus five tins of another brand. I’m good for life. My old Benjamin 22 is well supplied also (got it in 1958, had it rebuilt in 1985). And, there is the Diana 177.
I don’t find time to shoot them much lately playing nurse as my wife is on a serial surgery plan. Ankle, ankle, knee next, foot after.
Any .20cal pellets shoot fine in my Sheridan Blue Streak. They are hard to find in a store, but many online vendors sell H&N and JSB brands. I get 20cal JSB Exact from Trenier Airguns because they are more accurate than the old cylindrical style in my 1971 Streak.This is a little off-topic, but what are you using for ammo these days ?
Original Sheridan pellets are (apparently) collector’s items now, even the empty boxes fetch a good price.
You can buy .20 caliber pellets. They just cost more. I loved my Sheridans. I wished someone made a current day equal. Try these pellets. No experience but I have shot H&N's in other calibers and they do make some quality pellets.
