I was looking at the steel blunts in 3Rivers, but I'm not sure what the reason for different diameters is. Is it to match the shaft? wouldn't the larger give you a better chance at scoring a hit?
what would you reccoment for a Beeman MFX?
5/16 would fit 5/16 woodies.
11/32 will fit over the taper and sit deeper on a 5/16 wood.
Then you consider your blunt weight.
For the screw ins, you are considering head weight.
IF you have the skinny carbons...throw all of that out...I haven't tried those yet!
I should have specified. I meant screw in's and yes i shoot skinny carbons. i shoot 125's with this set up, but they offer a bunch of sizes in the same weight
Someone will be along to help...Sorry, I couldn't sort it out any better.
But, I'll be learning with you.
All shafts are not created of equal diameter. The different blunt sizes are made for different diameter size carbon and aluminum shafts, such that they fit flush or perhaps a tad larger than the shaft when installed. A tad larger than the shaft makes them easier to pull out of stumps. The nominally larger size of the biggest compared to the smallest isn't going to make a difference re hitting the target.
