MY .308 HOWA ( 22" ) LADINGS (ontwikkeling)

Post by vriell »

Speel so bietjie met lood ( mold) koeels o.a. en die volgende data net ter inligting.Die loodkoeel met gas check het konstant ongeveer 2" groepering op 100m gegee (met al die kruite)en die gong op 200m(30cm) elke skoot geraak.250m (30cm) was so elke 4de skoot mis en blyk spoed probleem te wees.Probeer ook nog die "smering" kombinasie reg te kry (te veel rook) Kon geen "leading" waarneem nie...

Opgewerk na hierdie lading...kombinasie van kompres lading en seating diepte asook win doppe wat meer kapasiteit as bv. PMP doppe kan hanteer ( geen druk tekens )

Het klompie 143 PMP fmj koeels gekry en bietjie gespeel met ladingontwikkeling .

S335 = 43.5gr
TPL = 71.4mm
Chrony = 2740 vps

4 skote op 100m...nog nie 100% op node nie maar is verbaas en baie bly oor die koeels se groepering as in ag geneem word dat die koeels se gewigte verskil tussen 142.8gr en 144.3 gr...
Teen R2.00 'n koeelpunt vir sportskiet help dit darem om kostes laag te hou.. ><)
