Does anyone have a 6 PRC?

If so, are you willing to share some load data? Don't need specifics just type of powder , type of bullet and any charge weight that you found to be a good starting load.

6 PRC

Have spent just a little time behind this cartridge now. Rifle was built by TS Custom. KS1 Adjustable Stock Bartlein 7.5 twist 24” Rem Varmint Lone peak Fuzion Alpine cut M5 with hinged floor plate March FX 4.5-28X52 I’ve only tested H4831SC so far because I like how consistent and clean...

Thank you. When I go to the search option and type in 6 PRC, this is not one of the options to look

I have data for the heavier bullets, but I was trying to shoot the 75 to 90 grain bullets. Just wanted to verify the type of powder good starting point. Currently building a GRT cartridge profile so I can use that too.
Helpful info, thanks

6mm prc

Anyone playing around with the 6mm prc? I see the 6UM post but I’ve got lots of prc brass that I can use. Wondering if I’ll be able to move a 108gr bullet 3000fps+ with an 18” barrel? Would you do the 6mm prc again or keep it simple and stick with the 6.5 prc?

Just based on the case I'm thinking n550 or even n540 or h4350 would be where I'd start.

You gonna try the vt bullet?
 
In every case similar to this capacity using light bullets, you can't go past Varget, H4350 for medium/heavy weight bullets.
Sometimes Varget wins at the 100g level, but it can swing in favour of H4350.
My (2) 6.5x47 Lapua cartridges swing with 123g bullets, the target rifle, heavy 30" barrel, likes H4350 and my hunting rifle skinny 24" barrel likes Varget, velocities are similar with either powder in both barrels.

Cheers.
 
I forgot to mention, have been hunting with Lapua 123g Scenar OTM and Scenar 136g OTM in the 6.5x47, my buddy is running a Scenar 108g OTM in his 6x47. Another 6mm Scenar bullet he uses is the 90g Scenar-L, although a target bullet, pigs fall to them easily.
I haven't used anything else except 129g Nosler ABLR in mine, they grouped into 3/4 to 1MoA but I didn't take it further, only used 1 powder being H4350. I also had run out of WLR primers at the time and used Fed 210, I believe WLR primers would have tightened the group some.

Cheers.
 
First 50 shots on the new 6/6.5 PRC.
I had to use a 90 grain ELD bullet because it does not have a lot of free bore.
COAL touch is 2.783
COAL 2.763 when firing
H4350 53 to 54.5 in .5 gr increments
GRT believed 52.8 would be my first node
First shot on the left 53g dot was cold bore/sighter. Then moved it down for the final four.
What are your thoughts or input?

I think it is a little hot. I will back down to 53 or so and verify at distance. Always got my EC tuner to tweak the load.
Might try RL16 & V550 too.
