I have the GIRamrod with Spinjag loader on my Accura V1 with a Spinjag on my short starter. Set-up works great for me and helps with loading for sure. I use mine both at the range and while hunting.
If you call them on the phone and tell them what rifle you have they will know what Ramrod and length you will need. Great people to work with. When I ordered mine online I made a mistake and the next day I got a phone call from them to confirm what I needed. Can't ask for better CS than that.
Worth every penney I paid as far as I am concerned.
