Sorry, havent been here in about 7 months so others might have posts other places about this.
I built a 7mm PRC 5 years ago. Feel like I built it into what would IMO be the best platform for big 7mm bullets. How and what did I do?
Simply - took 300 PRC, kept all the SAAMI specs and necked it down to 7mm. I felt like it was a prime opportunity to run 175, 180 and 195 bullets with a good powder to bullet weight ratio that produces >3000 fps speeds for hunting.
I like to run hunting bullets as fast as I can, as long as I find a node that is under 1/2 min. I shoot my hunting rifle about 60-90 rounds per year so burning the barrel is not really my primary goal. It is hitting that animal as hard and as fast as I can.
Built on a BAT Action
PROOF 8 twist barrel
AG composite stock
Kahles Scope
Triggertech at 1.5 lbs
I run 180 grain Bergers with 79.0 grains of RL 25 and see 3192 fps with an avg SD of 9. Was able to get ADG brass that necked down easily and didnt have to fire form with the custom reamer specs we used.
My issue with the Hornady offering is in a short action rifle - which everyone seems to want for light weight, you have to sacrifice something. Primarily, if you want to run ELR super high BC bullets, you have to shove the bullet so far down into the case, you lose powder - for targets....fine. IMO, not optimal for hunting a LR distances
Yes, exactly.What you built is a 7-300PRC, which is different than the current SAMMI 7PRC.
The saami 7 prc isn't a short action and isn't cramming bullets down into the case. This is one of the main reasons why Hornady made the 7 prc. Your 7-300prc is way more over bore and not nearly as balanced as the saami version. At that point you're up there close to a 28 nos and barrel life/ recoil and overall rifle shoot ability won't be as good. But it'll be a lazer for around 500 rounds or so.Yes, exactly.
Yeah, not so much but ok. Not overbore at all and way more life than 500 rounds LOL. All good though, enjoy yours!The saami 7 prc isn't a short action and isn't cramming bullets down into the case.

Nice, sounds like they should fit in a Tikka with a Red Snake Tactical bottom metal.26 inch barrel and my ogive measure is 2.653 I will have to recheck the coal I'm running them. 020 off
Going off of Bergers dimensions for the 190 that sounds about right.I will check for you on coal in a bit but off the top of my head I'm thinking I'm around 3.420ish or so
