7 PRC

dustbag · Sep 21, 2024

Had a chance to put some rounds through my new rifle. Most parts came from this forum. Did the work myself. Plan is to run 153 HHTs but starting break in with 175 ELDX. Ran a pressure test today and didn't find any yet.

Defiance Anti
Manners LRH
20" Proof 8 twist Sendero
Hawkins Hunter DBM
TT Diamond
Ultra 7
Leupold vx5HD

175 ELDx 3.3185 OAL .020 H1000 Garmin
100 yard target just looking for pressure.
66 - 2712
67 - 2751
67.5 - 2767
68 - 2818
68.5 - 2845
69 - 2852

No pressure signs. Have RL26 too. Haven't decided if I want to burn it up though.

Nice rig

66.3 grains of rl26 and a Berger 180 hybrid put me over 2900 fps out of a 22" barrel, same cartridge

I use H1000, way more available. (Just picked up 2 jugs) you may want to keep the RL26 for special somethings. It is no longer available.

I'm shooting H4831SC with a 180 hybrid at 2940 with a 24 inch barrel. Has Ben working great.

Have some H4831SC on shelf. I will try some of that too. Thanks!

To be more specific, CCI 250s, ADG brass, 64 gr H4831SC, load safe in my gun.

My build just didn't seem to like H1000. In my 24" barrel the RL-26 gives me better velocities and accuracy. I had issues with early pressure signs with both powders but have since fixed that with the Alex Wheeler reaming process. Burned through a bunch of components figuring that out. Anyway, headed out next week to run 66 through 67 grains of RL-26 and find the sweet spot. I have a few hunting seasons left of the RL-26 before I have to switch to something else I have on the shelf (StaBall HD, Ramshot Grand, and H1000). Learning is sometimes expensive...

That's a nice build. Considering getting my paperwork started on the thunderbeast for something similar

Hi, what is alex wheeler reaming process? Is there a post describing it somewhere or is it secret? It is my understanding that 7prc had issues with initial reamer design and clickers but I have not been following the whole saga.

Can't seem to copy the link but search this thread.

Sticky Bolt Ideas?

BINGO!!! WE HAVE A Winner! if he was only having tight brass I'd agree with you, but seems hes also getting ejector marks, Personally I'd wager he's making pressure for what ever reason, I'd back the load off
