My take on the Streamline .25

Hello again Mac,
Regarding the 34 grain pellets...800 ft/s will be accurate but it is far from their best performance. When they first came out we all experimented with shooting them at different velocity and in the beginning about 830-840 ft/s was the velocity most guys thought was best. One guy even won a tournament shooting them at about 835 f/s according to him. But ever curious, and rarely satisfied to run with the herd, I got to thinking that 880-900 ft/s is the best velocity for all the other JSB pellets out of these Smooth Twist barrels and wanted to see if that also held true for the 34 grainers also. I found that there is a midpoint around 850-860 ft/s where they weren't quite as accurate for me, but that as I kept going higher and higher the accuracy not only came back but both my rifles began shooting like lasers at 50 yards! Brother I mean just stacking pellets one on top another! 

Yesterday I cleaned and inspected my Wildcat and changed the breech o-ring as routine maintenance and cleaned and polished my hammer and trigger sear. Afterwards I shot it over my chronograph here in the living room and was getting an average of 911 ft/s, with a high of 916 ft/s and a low of 911 ft/s with the 34 grainers...not to sound like I am bragging mind you, but I presently own the most powerful .25 Streamline and the most powerful .25 Wildcat on planet earth, and if you choose to do so I will tell you how to have the most powerful .25 Streamline in all of Scotland! You will be the envy of all the other lads at your shoots and be treated to more drinks than a sensible man would even accept! Which may lead you to a predicament where you wouldn't want to insult anyone by saying no to a drink that's offered, and yet already had more than is prudent. What will you do then? I hope you won't have to fight your way out of your pub for God's sake!
:)
All the best, Chuck
 
Oh and one other point Mac,I can turn my Streamline .25 down to its medium power setting and shoot the JSB 25.4 grain domed pellets very accurately at an average velocity of 700 ft/s which yields 27 fpe…which is perfect for most small game at close range. Or I can set the power wheel on low and shoot 19.9 grain H&N Field Target Trophy domed pellets very accurately at an average velocity of 650 ft/s and get about 18 fpe…great for small game at close range or close range target practice. So I have the best performance possible from .25 caliber on high power, similar performance of a .22 on medium power, and the performance of a .177 on low power. This kind of versatility is hard to beat! And it is a simple matter to adjust my scopes elevation for each different setup by just referring to my shot book.

Thanks again Chuck, a very useful link for the gauge. Drinking, fighting and even spending money on guns has taken a back seat following the arrival of a newborn, however the wee boy can only distract me for so long.... Following our government introducing licences for all airguns increasing numbers are simply going fac given it is not much more bother so more powerful airguns may become the norm over here which is a good thing in my view. I have already out shot my cousins 22lr at fifty yards to school him on some of the advantages of air, if I can set up the streamline like yours then I could maybe give him a run for his money at 100 yards. 
 
Hi txrpls,
Sorry for the delay in answering...been busy with work last couple days. My Streamline shoots the 25.4 Exact Kings at an average velocity of 1004.6 ft/s, which as you know is way too fast for them to be very accurate. At 50 yards I get a scattered non concentric group of 1 1/2" - 2"... :no:
Best regards, Chuck
 
Hi Mac, If you decide to switch out your gauge I recommend you order a Wika from CSG.com: http://www.csgshop.com/product.php?id_product=248 They are currently out of stock but I spoke with the owner yesterday and he says he will have them back in stock in about two weeks.

Back in stock . . . 35 available on Thursday, 21 on Saturday !
