6BR, do you like BR-4 or CCI-450 better for heavy bullets

This is what I saw with Varget and 105 Hybrids in my 6BRA

What did you see for change in velocity and Es for those?

What range is that?

I didn’t chrono them. Wish I would have

 

[Nature Boy]

What range is that?

100 yards

 

[Nature Boy]

I assume you went with BR-4

Actually no, I used the 205M. It was really almost a coin flip.

I’m currently doing some load testing with 107 SMKs and 108 Berger BTs. I’ll have a chance to revisit this test again with those bullets

When I buy a house and get mh shop back up and going one day... I want to try 450s in the BR. Been running br4s and it stacks thrm at 100, bug have done much load development... i fould a load that they bugholed at 100 then let my wife start shooting it for deer and targets.

I shot it in a 600 yard F Class match and scored a 592. Vertical was not a problem.

Gift it to the little woman and start a another for yourself (BRA that is)

I'm saving the 450s little something extra for a load I'm working on.

Ah I built it for her, its her gun... I just fell in love with the 6BR after doing it though. I want to build another, but im still working on wearing out a 6XC barrel.

 

[Nature Boy]

All we can do is test em for each rifle right??

I think so. And every load.

The Rem 7 1/2 worked great in my fire forming load but were crap after that

 

[Sniper338]

Didn't you have that 260 Remington that shot a dime a 300

Yes. Still have it. Havent shot it in a while, screwed on a few other barrels playing with other things since then. Im a sitting duck right now though. Sold our house so all my gear is in storage and in closets at families houses..

450's with 105 Berger Hunting VLD's

Did some testing today at 200. Cci450 seemed to be the winner with varget in terms of groups and spreads. However it lost about 40 fps over the fed 205m. However h4895 and fed 205m was the winner over varget and cci450.
Sellier and bellot also seemed to work well with h4895.

This group pictured is vapor trails at 200 yards with h4895 and fed205m.

My 6BR likes Varget and Wolf/Tulamo primers better than CCI 450.

My 6BR likes Varget and Wolf/Tulamo primers better than CCI 450.

Have you been able to find wolf/Tula primers recently?

Have shot all the above mentioned primers and Wolf/Tula shot better for me also bought a case when you could get them]

 

[Nature Boy]

We need more Russian collusion so we can get more of those primers again
