mr williamson Posted September 28, 2012 Report Share Posted September 28, 2012 Hi guys been trying to find out the muzzle velocity of rws's 12g Rottweil special 36g no 6 cartridge. I checked the rws website but no joy. Do any of you guys know? cheers Quote Link to comment Share on other sites More sharing options...

Floating Chamber Posted September 30, 2012 Report Share Posted September 30, 2012 (edited) 'Velocity' is a vector. Speed would be the correct word to use unless you specified the DIRECTION of travel (i.e. West). SPEED is DISTANCE divided by TIME, and distance is the difference between two points. Therefore, at the moment the payload leaves the muzzle, 'DISTANCE' = ZERO, and TIME = ZERO. Hence there is no TRUE muzzle velocity. However, using BARREL TIME*, (the TIME it takes the payload to travel the LENGTH of the barrel) AFTER the striker touches the primer cap of the shell, and the length of the barrel, an IDEA of MEAN muzzle speed can be calculated over a series of shots. * even barrel time varies considerably from shot to shot because of numerous factors like friction, heat, primer brisance, varying propellant and shot weights. A very slight difference in any one or several in this list will affect pressure, momentum, speed, barrel time, even if the shells have been 'clinically' loaded with accurate scales and constant closure force. So, really, to quote a definite M.V. would be misleading but some manufacturers do give an idea....others won't commit themselves.

clayman Posted September 30, 2012 Report Share Posted September 30, 2012 but why do you want to know the MV? It tells you virtually nothing about the cartridges performance. because there is an obsession by many buyers with "faster is better" many quality cartridge manufacturers dont quote anything - they rely on the reputation of the cartridge having a good PATTERN. Its pattern that counts, not MV - and in most cases better patterns come from SLOWER cartridges. A quality 1300fps MV cartridge will probably have 80% of the pellets in the effective pattern, while a cheaper 1450fps might blow 50% of the pellets wide as ineffective flyers outside the ideal pattern spread.

wymberley Posted September 30, 2012 Report Share Posted September 30, 2012 Notwithstanding the previous remarks (I bet you wished you hadn't asked), the answer to your question does however reflect the validity of those remarks and partially explains why it is a damned good cartridge. 380m/s or 1250 ft/sec.

mr williamson Posted September 30, 2012 Author Report Share Posted September 30, 2012 I will say this rws, namely the ( rottweil special 36) is a fantastic cartridge.

deershooter Posted September 30, 2012 Report Share Posted September 30, 2012 Measure it with a calibrated chrono and it still will not be what is says on the box Deershooter Quote Link to comment Share on other sites More sharing options...
wymberley Posted October 2, 2012 Report Share Posted October 2, 2012 I checked the rws website but no joy. cheers Sorry, forgot to mention it: www.ruag.com then go for ammotec from the options and follow the trail from there. Quote Link to comment Share on other sites More sharing options...
