300 yard benchrest gun,... what would you shoot?

[Lefty Trigger]

Looking for ideas for a new 300 yard benchrest rifle for next season. I'm not concerned about the type of action but the chambering and why. Groups are king,.. let's here your ideas.

Weight not a concern?

Easy.....6PPC.... History......Experience

No,...

 

[jimmymac]

Then I’d build as heavy of a bench gun as practical and chamber it as a PPC.

 

[halfmoanut]

No,...

Build a 13.8lb PPC, HV.Or a 17.8lb PPC long range rifle. PPC'S are the most accurate cartridge in the world have been for a long time! Just ask anyone who just attended the Tack Driver!

Need more detail for the PPC cartridge...
I found a 6mm PPC and a 6mm PPC Sako and a 6mm PPC USA?
.262, .263, .264 and .270 neck... was told .264 is most common.
What twist rate for up to say 80gr... 12 twist?

 

[jimmymac]

I’d say that a 268 neck is more common these days. Turning necks is nice at that dimension because you can get away with one smooth pass. You won’t be shooting either of the latter two you mentioned. Most precision gunsmiths will have a house reamer, or you could get your own. 65 to 68 grain bullets are your friends.

I have a bunch or 64gr, 65gr and 68gr bullets so with that selection would you go 14 twist?

That will work fine. A lot of guys are running 13.5 twist these days. Either works. I haven’t really seen a difference.

Have not settled on anything yet but eyeing Benchmark barrels...

 

[jimmymac]

Can’t speak to those, but Bartlein and Krieger seem to be the most popular amongst the BR crowd.

 

[jimmymac]

@Chris Mackey is the go to guy for a good barrel at a fair price.

 

[std7mag]

I'm building one in 250 Savage.
But i'm not exactly a follower.

Wait.....
Then why did you tell me 6BR, last year?

 

[JEFFPPC]

I got smarter.....not bad for an old guy, huh.

 

[LRPV]

I believe Bart won the 2021 Tackdriver with a BRA and 103’s.

You are correct. 2 out of the top 3 shooting 6PPC. I think the 6 is the answer regardless of which one.Its the shooter not the cartridge, If Bart had picked the PPC it would have been 3 0ut of 3.
