    http://castboolits.gunloads.com/showthread.php?341474-Pneumatic-Swage-Press this is my setup. i got it finished about 3 days ago. sure beats the heck out of using an arbor press for everything, lot faster too.

    this is 120 pieces of 500 that i did with my pneumatic press yesterday.. these are 130gr varmint bullets fresh out of the polisher. i do about 100-150 at a time in my polisher as more than that seems to bog it a little, hell it is just a...

    im gonna say it is at least a 3in cylinder.. with a 3in cylinder you can get 950lbs of force push and 848lbs pull at 135psi.. i wouldn't go smaller than a 4in though. with a 4in you can get close to 1,700lbs of push and close to 1,600lbs pull at...

    grade 8 bolt makes good dies, that is what im using right now to swage my bullets with.. first i anneal them at 1,300*F-1,400*F for 15 minutes in my kiln and let them cool down slowly so they are soft enough to machine with no hard spots. i...

    yea, stable enough to fly point forward is a kind of stability.. and i agree that there is such a thing is too much spin.. they tried different twist with the .223 back in the day. one twist they had was so fast that the bullet was on the verge...

    what causes the decrease in accuracy with an unbalance bullet then? while it is true the bullet will rotate along the center of gravity as soon as it leaves the barrel it does not necessarily mean that it is stable in flight as the gyroscopic forces...

    an unbalanced bullet will not stabilize no matter how fast you spin it. if anything it will wobble faster around its center of gravity and the groups will open up even further.. but if you want to get into the older bullets not being as good as...

    there is one little problem with wanting to go with a very slow twist with a long bullet, and this might explain why the groups is so large.. a slower twist imparts less gyroscopic forces upon the projectile leaving room for destabilization and...
