H&N Barracuda 10.65 Match Pellets…

After about 800-900 pellets, I FINALLY found the one that works in my TSS….and I need to mention the size is 4.50mm NOT the 4.52..which is TOO large and shoots very poorly…the JSB 10.2’s in 4.52mm are also too large and not accurate!! Crosman Premier Ultra-Mags are so big that they actually lead-foul the barrel after about 15 shots 😥 Gun needs the smaller diameter, which I think is a good indication that it is built close to tolerance 😀 😀 😀 ..Nice thought !!
I shot a total of 110 pellets through my Alpha Shooting Chrony …here are results…..PW@4, TH @ 0.074″, start at 3000 fill..stopped at 1850 psi.
I use 5% as my extreme spread…..most gun makers have guns tuned to shoot 10%, I chose the smaller number so that there is less than 1/2″ change in POI ( at 50 yards) with gun zeroed @ 25 yards. high shot was 827 fps….5% of that is 41fps subtracted from high of 827 gives me a cut-off of 781 fps minimum. From the chrony sheets you can see that gives me 51 shots inside my 5% range, starting at 2750 psi, stopping at 2000psi. FPE is low of 14.4 fpe to a high of 16.0 fpe. This suits me fine, as I have an AA S410 that shoots 29 fpe if I REALLY need to damage something 😆 😆 Chrony sheets are posted for reference…
