Results are similar on my early 50’s Silver and Blue Streaks, thanks for sharing.
Wow, awesome Gary, you are putting out some good info. Here are the average numbers for a '57 Blue Streak I resealed (13 grain polymags):5 pumps- 5516 pumps- 6037 pumps- 6168 pumps- 629And a 57 Silver Streak untouched internally (14 grain jsbs):5 pumps- 4366 pumps- 4857 pumps- 5088 pumps- 574
Healthy Streak you have, Gary. Right close to my '67 which tops out around 650 with 8 pumps and JSB 13.73. The heavier Benjamin pellets actually move a touch faster, I suspect because they fit looser in the bore. It has original seals except for the pump cup. My resealed '64 performs almost identically. I might add, they both shoot better than I do.
my old thumb safety streak with 8 pumps avg 610fps with H&N 11.42gr FTT … I’ve not been inside it since owning it & always wondered when it would be due for rebuild but seems ok based on info here. Thanks
I don't recommend doing anything to one as long as 8 pumps will shoot at least 600fps. with those BS 14.3 pellets. Around 650fps is about average , so even if it drops down to 600, you have only lost approximately 10% of its original power. It is up to the owner if they want to work on it to try to get that 10% back.
Mine's a bunch newer being a 1973 and I only chronied the JSB's, but...-JSB 13.73: 6 pumps - 6038 pumps - 665-JSB 15.89:8 pumps - 636
My averages with 14.3 BS pellets have been ;630-650 fps With JSB 13.73 640-660 With JSB Heavy 15.89610-630 With H & N Target Trophy 11.2650- 670 fps. Most accurate to least accurate . ( old eyes )Both JSB ‘s about equalH & NB & S But even the worst pellets ever made were good enough to provide meat on the table. This is due to the inherit accuracy of Sheridans, I my opinion.
Mike & Tim ; Have you oiled the cup of your Streaks , lately ? Performance is a little low & a couple of drops of oil may be all it needs. Do not use any petroleum oil, though. Non detergent 30wt oil, transmission fluid, Marvel Mystery oil, Pell-Gun oil, are a few choices.
