Need to look into the satterlee method of load development. Only way to go. Used it on 3 guns and will never use any other method again. Too fast and too easy

Well just for the heck of it I shot it over the chrono with just 25 rounds on the barrel. 105 hybrid, 30.0 RL-15, Fed 205M, Peterson brass got me 2860 fps over 15 rds. Sd wasn't great at 14 but I think switching to CCI 450's will help with that.
I have to agree on the 450s. My SD was in that 16-18 range with federal match primers and dropped to 7 with the 450s.
You really had that high of an SD with the 205m primers?? I had quite the opposite. I had a sd of 2.9fps with the 205m’s and with BR4’s I had a sd of 4.
Though to the uninitiated one might see this as a harsh response. My first custom action was a Defiance Devient tac. At first I was nervous that it would Jack up my round if it didn't feed right and so I ran the bolt like a pussy. However, when I learned the error of my ways and if you run the bolt with full commitment....... It was as though it was a completely different action. So smooth. Fed perfectly. So avoid my learning curve and drive that bitch like ya stole it!!!!
26" Bartlien 5R 1-8 w/ Berger 105gr HT, CCI BR4's, and 30.4grs of Varget gets me 2895fps
Its out there, it took me about a month, but within a week I was able to get 26lbs and that was only due to purchase restrictions.
Find 4-5 websites that stock Varget and show "in stock" figures. Check them 3 times a day (breakfast/lunch/dinner) and you will find Varget easier than you think.
Ordered a barrel, berger hybrid 105's, and lapua brass.
Need to order dies and bushings. What's everyone liking?
I really like the rcbs seater dies with the window. I also have le wilson fl bushing dies for 6.5 creed and valkyrie. Thinking of going that route again.
What size neck bushings should I order with lapua brass and 105 hybrids?
Thanks

i recommend getting harrels fl bushing sizing die. you shoot 3 rounds and send them your brass. they send you a die that closest matches your chamber. and they are only $80.
i use a .265 (some use .264) bushing to oversize the necks, then run them back over a mandrel to set final neck tension.
i use the rcbs match master die for my .223 and it is really nice.
however i stick with my forster micrometer for seating on my 6br
Those are the dies I have, just non bushing dies. It has the micrometer seating die. I did have to take a bullet and 600grit sandpaper to the seating stem because it was leaving a ring around the tip of the bullet. I use the berger hybrid 105s.
I'm on my 7th. The bolt is getting sticky on some cases though so I might need to by a small base die.
Let me know when you find a place that makes 'em...
small base 308 die.
Close, but not quite the same.
The ring die I have has zero chamfer at the base, and sizes *all* the way down the case web as far as it can get to the shell holder, whereas a SB die squeezes a *little* smaller, and has less radius/chamfer at the base than a regular F/L die... but it physically cannot size as far down the case web as a true ring die, both because of the chamfer/radius, and because you have to be conscious of not pushing the shoulder back too far.
I need (well, 'want' would probably be more accurate) a ring die or two in other case head sizes to go with the one I have. That one was custom made, but the guy has gone radio-silent since then. PVA was supposed to be making something similar that they called a 'small base' die that used bushings... but they don't even have it on their web site anymore.
Like I said, let me know when you find someone who makes a ring die. I'm interested.
whats strange is that your having issues with a BR I shot a few barrel and never had any sizing issues.

Not sore on reamer and no mention of neck turning.
Called bugholes and told them I wanted a
6br and I wanted to use lapua brass and 105 hybrids.
Will give them a call and see what they say.
Thanks
if your ordering a prefit its not(i should say i doubt)going to be a tight chamber.
My 6br load is slow compared to everyone else but went with accuracy & components I have on hand.
H4895 - 28.4 grains=2813 ES of 9
Fed205M primers
Lapua brass
105 hybrid loaded .040 off lands ( wanted boat tail near shoulder/ neck junction)
Also wanted to mention, you guys having carbon issues, did you see where Eric Cortina said he uses CLR to clean carbon from his barrels? CLR is a household cleaner I also use to clean my screens & sprayer nozzles on my herbicide applicator when storing for winter. Calcium, lime, rust. Is what it stands for.

1# canisters of H4895 are in stock at Powder Valley. I just watched the 8# go out of stock so you’d better hustle.
Thanks for the heads up, ordered some 5 minutes after you posted!
My regular load for 6mmBR is with H4895. I have Varget & H4895 on hand but I am weighing my options for future powder scarcity. My question is does anyone have a load using Norma 203B ( I know not temp stable) or Vihtavuori N540 with either 105 hybrid or 108 ELDM? just looking to expand my powder options.
I'm using 540 right now.
26" 1/8 twist tube from PVA
29.5gr 540
105 hybrid
450 primers
2 times fired Peterson brass
10 thousandths off lands
1/4-1/3 MOA at 100yds.
