    7mm PRC reloading advise

    I get 2900fps =/- out of my 22" Proof barrel running a 175gr ABLR with 69.3gr N565 out of fired Peterson brass & a Rem 9 1/2 primer. BTO of 2.6650". More importantly, it's an accurate load. I loaded up to 71.3, but saw no accuracy improvement.

    340 Weatherby woes

    Norma MRP was the best, but a close second is 7828ssc. In my Accumark, 250gr Nosler Paritions and 250gr Sierra Gamekings shot sub-moa all day. Play with seating depth. For reference, my last elk killer load was a 250gr SGK pushed @ 2960fps by 86.5gr of 7828ssc seated at 3.068" BTO. I had loaded...

    Reloading 7PRC

    I have the Forster Micrometer die set with the FL bushing resizer, but other die sets such as RCBS, Hornady or Redding are excellent too.

    N565/570 a legitimate RL26 replacement?

    I've run N565 in my 7 PRC with 175gr Nosler ABLRs. The first rounds I used Fed 215 primers, and now I'm going to try Rem 9 1/2M primers. After that, WLR primers. I'm just waiting on new scope rings before I do further load development. Out of my Proof Research 22" barrel, 69.7gr N565 gave me an...

    Staball Hd 7wsm

    According to the GRT Discord-obtained Staball HD powder profile, and plugging it into a 7mm WSM with a 22" barrel and 175gr EH, I get a charge of about 67.5 grains at 62,846psi, giving 2727fps. 63 grains will put you at 50K psi. NOTE: I have not used the Staball HD powder profile enough with my...

    340 Weatherby and H1000

    "Poke a few deer with it" is a rather subtle way to put it with a 340 Bee. Iffen you shoot anywhere near one, it'll die, LOL!

    340 Weatherby and H1000

    My favorite cartridge. I never ran H1000 in the 340 Bee. 7828ssc, Norma MRP and RL22 were all good. 85gr MRP was my favorite with 250gr SGKs pushing 3000fps into 1/2 inch, then 86.5gr 7828ssc right there too. Killed elk far away with both loads.

    Nope. There is a divot by the ejector.

    No, it seated fine. The hole is in the side of the primer, which caused brass melt.

    Pic of Winchester LR primer. First shot and only shot! Yikes! Maybe a bad primer lot. Gonna call Winchester Monday.

    I'm using the mild Rem 9 1/2 Magnum primers, and the hot Winchester LR primers.

    7mm PRC & N570

    I just ran N565 in my 7PRC, 22" proof barrel, using Nosler 175gr ABLRs. Best results were with 69.7gr at ~2924fps with an ED of 4 (five shot is a small sample size, but still.....). Group was a touch over under .75", but it was gusty. 69 gr. opened up to about an inch, at ~2887fps with an ES of...

    7mm PRC and IMR4831

    Great info. Thanks. I managed to get my hands on a brick of Rem 9 1/2M primers, which are the mildest of the magnums. I'm going to use them, and then try WLRs, which are the hottest of the LR primers.

    7mm PRC & N570

    I can't find the RL26 pixie dust anywhere, so I am ordering a few pounds of N565 to try with the 175gr ABLRs out of my 22" Proof barrel. After running a few scenarios through GRT, it seems to bee the best balance between case fill, burn, and velocity. I'm sure it'll be accurate. Vihtavouri says...

    7 PRC Powder

    Is there any way you, or anyone else, could send me the 7 PRC update file for GRT? I am getting nowhere with the Discord support bot. I registered in 2018, but did not verify my account, and can't do it now because I don't remember my password from 6 years ago. Like Elvis, I'm caught in a trap.

    Thanks. I can't seem to login to the GRT discord server because it says my email is already registered and I can't verify it. Geez!

    7 PRC Powder

    How did you get 7 PRC in GRT? My updated version doesn't include it. Are you using a predecessor wildcat?

    VihtaVuori and 7PRC

    I posted this in another thread here yesterday. Today I'm going to run some more with 66.7gr N165 at a longer 3.3020" COAL. Just ran some N165 thru my 22" proof barrel (~130rnds) , 175gr ALBRs seated to 3.2600" COAL, or 2.5855" Ogive Fed 215 primers Hornady once-fired brass Temp 52 F 65 gr -...
