7 PRC shell holder numbers

[Mike6158]

I don't have a 7PRC (some day) but I thought the 7 PRC is a 6.5 PRC necked up? I have a Redding #6 that fits my 6.5 PRC brass. It's for my 7mm Rem Mag when I anneal in my Amp Annealer. Hornady says the 6.5 PRC and 7 PRC are based on the .300 RCM case (which is based in the 375 Ruger as already mentioned. Tomato / Tomahto). I don't have a Redding #4 so I guess I'll pick one up.

I’m not sure what the difference is between their #4 and #38. I couldn’t find any info. I looked through the RCBS charts, and it now lists the 6.5 PRC as #38 along with the 300 PRC. However, it lists a #4 for the 375 Ruger, 338 RCM and 300 RCM. All 5 of these, are based off of the same case design. Then they list many other cases to use either of these 2 shell holders. Maybe there’s a slight change for extractor groove.

Might be a good way to sell shell holders.
