Been working on this r10 for quite awhile now. Its been a gun I wanted for a long time and I got to put some nice touches to it. Im extremely pleased with how it came out and would love to hear some feedback ( pos or neg)! Ive tried about 4 barrels and settled with the following:
Bsa r10 se .22 cal
lothar walther 23.8” polygon choked .630 dia
brocock magnum shroud ( functional)
donyFL sumo .22/.25
solid peek hammer with steel striker tip (18gram)
shortened spring
shortened stroke
peek valve .225 dia, .200 throat, .087 stem ( flat face vs stock tapered)
ported to .187 throughout
ported and contoured probe
huma reg at 140 bar
light valve return spring ( ported cap)
280cc bottle ( thanks charlieF)
tuned trigger
MTC f1 4-16 ffp
Performance:
30 shots on reg
jsb 25.4 mrd’s at 955fps
50 yards has been one hole pretty consistent. No groups at 100 yet but some random shooting at cans etc. has shown them stable at that distance. Couple shots at small rocks out around 150 and still looks stable. Overall I dont think I could ask for anymore. The shot cycle is whisper quiet and short and snappy. Around 50fpe so plenty of power. Shount count is OK considering the bottle size. The report of the gun is unreal quiet so it will make a great hunter!
