Sinclair shell holders

I use a primal rights CPS primer seater and tried the Lee shell holder and was disappointed by the results. Saw and bought the Sinclair shell holder and am impressed by consistency of primer depth. Now I have the Sinclair brand for all of my calibers Im reloading.

Nicely machined

I find it amazing that the Sinclair primer tool description says it can use Lee shell holders with some Dremel work. Do not bother. Unless you are a glutton for punishment just buy the Sinclair holders you need to start with.

Just what I need to hand prime an oddbal

I shoot a somewhat obscure cartridge, the .218 Bee and find that I have far greater control over the quality and precision of the finished product when I hand prime each case and this shell holder gives me that control when I employ the Sinclair hand priming tool.

Awesome Precision

I purchased a Primal Rights Competition Primer Seater and it uses this type of shell holders, I had the Lee shell holders but really was'nt happy with thier quality. I was looking for something better and found the Sinclair Stainless shell holders. I ordered these in all of the Calibers that I reload for and was very impressed with the precision and quality. This is THE shellholder for precision handloading.
