29.5 grains of Varget for 6mmbr, to much?

LR_Shooter - if the bearing surface is close to the neck/shoulder then the chances are high that you are going to have issues, more so if you use a bushing sizing die. Even if you go to the harder thicker primer, at the very least you will get flyers.

If getting the throat re-done isn't an option then depending on your use you may want to try the Berger 95 VLD. My Howa is throated short for 75 - vmaxes, the Berger 95 has a very short bearing surface but a very high BC. I just completed a ladder test with it yesterday and using 30.5 varget, cci450s I am ~2900 fps (looks to be an accurate node to work on) which is easily enough to get me to 800/900 yrds and a marginal 1000 yrds with the .249 G7 BC.

As the nose is so long and the bearing surface is so short there is still a ton of room to do the Berger seating depth test to really tune the load.

Anyways good luck.

I think I'll get throat extended a bit so I can seat bullets farther out or I'll get Shilen drop-in match barrel. Right now I'm bedding its action, which supposed to be supported by 3 pillars, which had no contact with action. Any way I have a hunch, that bedding it will improve groups, but will see...

If you are seating the 105 Scenars or 105 A-Max anywhere near the lands, you do not have a freebore problem. At an OAL of 2.330", Scenars are seated to a .275" shank depth in a .322" neck. The bullet base location is only relevant to fill percentage. Most 6BR reamers intended for long bullets have from .100" to .120" freebore.

Bedding will definitely improve your groups. Savage's "pillar bedding" definition is not the same as most other folks. It usually does not mean three steel tubes pressed into the stock that do not touch the action. Savages are also notoriously sensitive to action screw torque, especially the rear screw.

All that said, I still like Savages. I will shoot my .308 Savage in F-TR next month at a Camp Pendleton 5X1000 tournament. It has won for me before, even beating a few F-Open guys. Like most other factory rifles, Savages may need a bit of tweaking to shine but it can be worth the effort. BTW, the .308 barrel is a 30" Shilen Select that shoots and cleans well.

 

[LR_Shooter]

sleepygator, I marked bullet at the case mouth, then pulled bullet out and yes with 2.330" its right there at the border of neck shoulder.
Savage is not bad rifle, I like my Savages, sometimes they require extra work, so any other factory rifles.

LRShooter
SleepyGator has it spot on.
It looks like the firing pin clearance in your bolt face is too sloppy.Greg Tannel at Gre-Tan rifles specializes in fixing this very problem and is both fast and cheap.
If you look at your primers in your first picture the edges appear to be rounded.If your up in the pressure zone they will be flat and there will be no gap between the casehead and primer anywhere.Yours don't appear to be filled in and look very round.

I shoot 30.1 grns with CCC 450's - no pressure signs - 105 & 108 Bergers .010 in lands

 

[LR_Shooter]

last night I finished bedding this rifle and today I took it for a test drive, same load 29.5 grains varget and CCI BR4 primers, same seating depth. BR4 primers did work well, didn't notice cratering like with CCI 400, but today I had hard time operating bolt it was very hard to close and open, you can see scratch marks left by ejector. After firing this brass once, I neck-size it, I thought it should be perfect fit for my chamber. Any ideas why I'm having such issue? On first picture brass heads zoomed and 1st target @ 100 yards 0.495", this was made from clean barrel, I had 2 prior shots to sight it in, on the second picture second group I fired, but @ 300 yards 3 shots measure 0.746" 4th shot open up to 1.247. Then I decided to let barrel get more dirty, groups start to open up and I end up with 1.2"@100 and 3.3"@300. Today I fired total 40 shots without cleaning and I didn't notice any advantage of shooting with fouled barrel.

Are you jamming the bullets in the lands? Tell us where your setting the bullet.

 

[LR_Shooter]

no they are not in the lands, they more like 0.020 - 0.025 off the lands, I have hard time closing bolt with just brass , no bullet after I necksize or before.

 

[DennisH]

Headspace ????? Unless someone else has an explanation.

 

[CatShooter]

no they are not in the lands, they more like 0.020 - 0.025 off the lands, I have hard time closing bolt with just brass , no bullet after I necksize or before.

It would appear that you need to FL or bump size the case a few thou.

 

[LR_Shooter]

I tried to take picture of its chamber, that's closer I could get, there is ring appear to be dark, I think its from bolt rubbing against it.

 

[Steve Blair]

If you have a full length die, adjust it to set the shoulder back .001-.002 and try chambering again. If it chambers easily, you need to bump the shoulder. I FL size all my brass. My 6BR Stiller is now on 18 firings from the original 50 cases.

 

[LR_Shooter]

Yes I have Redding type s bushing FL, I was hopping to neck size at least 3 times and then anneal and FL size it, that's how I usually deal with other calibers. I can also use my FL just like body die.
So how's primers looking, should I still be concern?

 

[Steve Blair]

I would have Gre-Tan bush the bolt heads, it helped me with both the dished bolt face and primer cratering. Bushing would solve those problems. It is an easy experiment to fiddle with your FL die a bit and see if that eases your chambering problem. My two 12F Savages are both bedded and are still sensitive to action screw torque, so that is another area to investigate. Your load seems to be well within normal guidelines. The classic 6BR accuracy load is 30 grains Varget with a Sierra 107.

As I noted before, Savages just need some fiddling to produce best results. My Stiller Viper SS with Bartlein barrels installed by Stiller and stocked by Shehane in an ST1000, shoots groups approaching .10 MOA. Clearly, I paid more for that performance than I did for both Savages, extra work included. I still shoot one of the 12Fs in competition and do not feel at a disadvantage because of it. Keep eliminating the variables and the rifle will likely reward you.
