6BR 105 Loads

[Delaware_Ken]

Good Morning,
I want to do some load developement with my 6BR 1:8 twist 26" barrel using Berger 105 bullets. I've gotten some pretty good results with 30 grains of Varget, but I'd like to try some hotter loads using Varget. According to my reloading manuals, I'm shooting over the max suggested loads already. Has anyone had any luck pushing the 105's with more than 30 grains of Varget. If so, how far over 30 grains did you go? Of course, if I do go over, I'll go up in small incriments, and check for pressure signs along the way. I'm just interested to see how hot you guys have loaded up the 105's and still kept acceptable accuracy.

Thanks in advance for any info, Ken

I went to 31 gr. of Varget, but got a sticky bolt and backed off to 30. My rifle is a Savage.

Best load I came up with was 30grs of Varget, CCI BR-4 primer, 105 Berger VLD's seated .010 into the lands. Works for me!

Im running 30gr varget and a std primer. Tried the cci450s but shot better with the standerd. also i am jamming the lands with the 105vld's.

I have a 6BR and I can’t find Bergers, so I have been loading up Lapua Scenar L 105, best load was with N140. I have a 28” Criterion Remage Barrel on a Factory REM SA. That has not been Blue printed. 100 yards is getting average 3/8” groups.

Lol I swear I was on a new post, must of gotten side tracked by a similar post below.
Thanks. I put the 6BR together myself. Not a 0 or .12 shooter but I love the gun. Currently building a 30BR.

Lapua brass ? How much N140, if You don’t mind ?

Thanks

There's no harm in refreshing the tree-of-information once in a while.

My 28" Criterion shoots very similar to yours Doublejake.

I shoot a 6 dasher with 105gr Barts gungnir bullets and I developed a very accurate backup load of 29.8gr of N140 (I think this is a slower lot of N140 because my older dasher found the same speed using 29.5gr of N140). Lapua 6BR brass hydro formed to 6 dasher and then fireformed twice before developing load.

Magnum primers consistently shot smaller groups as opposed to small rifle non magnum primers.
