Rik , Harbor Freight makes a small cuttoff saw that does well on rifle brass.
If you are asking about the 510 Whisper....I doubt theres a form die in existence.
SSK has not been selling dies as of late.
Hornady will make you a set but it will be at the custom price and take 7 months last I checked.
CH4D has them on the die list but my last 510 client purchased the last set they had in stock.. they are also at least 6 months out.
There is also a shoulder that needs to be cut to the correct length which requires machine work. The dimensions are crucial.
Someone on this forum that makes the necessary adjustments to the Lapua brass on his mill ( I think) for a fee.
I turn mine on a lathe.
PTG makes a bolt body that will work in a Rem LA.
Have fun
