Jy is welkom om my te kontak ... baie jameer dat mens nie meer RL26 kry om die dop te gooi nie maar N560 werk ook mooi. Ek het nognie Norma se MRP probeer nie maar dit lyk of daai ook 'n lekker dryfmiddel kan wees.

Ek het lank S365 gebruik en dit het goed gewerk met die effe ligter koeels soos die 123gr en 130gr. Met die 140gr was dit ok maar toe ons internationale dryfmiddels kry het dit dinge bietjie verander. Nou dat mens die 153.5gr Berger ook kan skiet is hierdie regtig 'n baie nice kombinasie.

Dag se

My 260AI is ñ Savage met ñ 26" loop. Ek skiet nou ñ hele ruk VV N560 agter ñ 140RDF. En dit is ñ lekker kombinasie vir my. Ek het ook al die MRP gelaai agter 140 Matchkings, My spoed met MRP is so bietjie vinniger as die 560, maar my dop is ook bietjie voller.. Kan maar se bietjie compressed..

Dit is baie jammer dat RL26 nie meer beskikbaar is nie. Ek is nou op my laaste blik. Kry so 2820fps met 147 ELD-Ms uit ‘n 26” loop, Sako TRG 22, skiet bitter mooi met die lading.

Ek beplan om VV560 met die 147s te gebruik hierna.
