6mm-6.5mm PRC

[Boatninja]

I just happen to have a 6mm Bartlein blank and haven't been able to decide on which flavor of 6mm.
I'm sure that someone here has tried necking down 6.5 PRC to 6mm. Any thoughts positive or negative welcome. I have an awesome 6mm Creed I tried search, but no results. Please send link, info or whatever. I am partial to short barrels so 6mm GT etc not really useful. Thank's to any suggestions in advance. I don't mind having a reamer made.

Primal Rights has a version called the 6 PRC Primal and I think they are offering barrels, dies, and reamers to the public but not sure as it was still in development when I stopped following it. There is a thread on Long Range Hunting https://www.longrangehunting.com/threads/6mm-prc-primal.311545/ as well that might be helpful.

I thought about it for a hunting rifle but went with a 6CM as there wasn't a lot of movement on it from PR.

@rabeck27 Does excellent work, has a reamer on hand and a few of these under his belt. Check his post #36 for more details: https://www.snipershide.com/shooting/threads/6mm-prc.7158423/#post-11544635

unknownmunitions does a 6UM which is a 6-6.5saum I believe.

Pretty sure PVA has 6mm PRC on their menu too.

I am interested in a fast 6mm as well. Any merit going one way or other …6 saum 6 PRC ?

I would lean towards the 6PRC as Lapua 6.5 PRC brass is fairly available and 7 SAUM brass availability isn't as good.

There are threads on this chambering on rokslide and HuntTalk too.

I have heard report of 6PRC getting 3500 fps with 100 gr. Most of what I have read indicates that of the powders used, RL 26 gives the highest velocity. I have no personal knowledge, just doing some research for a possible next build.

I'm shooting a 20in 6prc on a bat vesper. 112 Barnes at 3140 with 58.2gr H1000. Pressure is around 59.5gr at 3230. Ran heavies up to 3300 with rl26 but why? It's super dirty especially with the can. I personally fell the capacity boost of the Saum parent is worth it over prc. Yes I shoot a 24in 6saum. It has the capacity to get to pressure with N570, 115s topped out at 3470. The 6 Saum was 3130 moderately compressed with N570 with dtacs.

My 22” is pushing a 90GR TGK at 3500 with 59gr of H4831SC
