300 PRC testing

[WildRose]

Ok…
So the light for caliber bullets (less than 200 grain ) that I'm using in my 300 rum that I'm shooting at about Mach 6.9, at less than one house MOA, that doesn't meet that criteria?

That 300 rum is throated for 215 and 230 Berger bullets

I don't know how you're going to manage that with excessively long freebore.

I don't know what "one house MOA" is either.

We'll find out how it works when I get time. I have a handful of the 153gr Apex Afterburners on hand and I'm going to order some 160g Hammer Hunters to try as well. I might get some Cutting Edge bullets to try too.

Shooting mono's that run 10% or more longer than conventional bullets is one way to use up that excess freebore so it should not be a huge issue.

1/2 MOA…

1/2 MOA…

Well congrats but that's certainly not the norm when you're running a gun chambered and throated specifically for the long HFC bullets.

The 300 PRC was specifically designed for the heavy for caliber bullets. To build one for lighter bullets really disserves the cartridge.

The 212 is a heavy for caliber bullet.

I'm aware of that, the question is about lighter bullets.

My son and are gathering the components to shoot lighter bullets he also just got a 300 PRC by Christensen Arms a Ridgeline.

Yep true but I have heard them doing pretty well with the 190s also.

I guess we should tell Weatherby they will never get a light bullet too shoot in a long throated chamber!!

i am glad somebody here has common sense. reading this and just shaking my head on what people will post on here anymore

One thing everyone knows if they shoot Hornady ELDs/Amax is they really love to jump. I've jumped them .150 with excellent accuracy. Typically .060-.080 is the norm in a couple rifles.

 

[WildRose]

Yep true but I have heard them doing pretty well with the 190s also.

Well then they must be throating them differently that Hornady was.

They were specifically throating their test bed rifles for the 200-250gr bullets during development.

That's a huge difference in length over the 190's and lighter bullets if you're loading them for minimal bullet sitting below the Neck affecting case capacity.

Thank you

 

[WildRose]

Thank you

Just keep in mind if you're going to build one from the ground up for the lighter bullets it should work just fine but discuss the particular bullets you plan to use with your smith and maybe work up a dummy round for them to use for determining how to throat it.

They did it by running a long easy slope into the lands which allowed for the bullets to ease into the lands rather than simply slamming into them.
