I was tasked with reclaiming a quantity of old 7mm x 57. Modern 7mm x 57 fits the RCBS #3 shell holder. I found that out quickly that old mil-surplus 7mm x 57 simply will not fit that shell holder.A little bit of research told me that 220 Swift cartridge bases and 7mm x 57 Mauser bases are similar. Not the same but close. So I ordered the RCBS #11 for 220 Swift shell holder to see if it would work with the lot of 7mm x 57. I was pleased to find out that, Yes, the old mil-surplus 7mm x 57 would indeed fit the #11 shell holder. I was able to use my RCBS Bullet Puller with the 7mm collet and the #11 shell holder and easily reclaim the pile of old vintage 7mm x 57. Graf came through with very quick delivery and competitive pricing. I am happy I did my homework, and purchased this through Graf and Sons.
