New to 6mmBR but getting frustrated...

[Nature Boy]

Despite what you read on the internet, there are precious few factory rifles that will do that "all day long."

What if you “do your part”?

Hi guys, new here in the forum. Being shooting and reloading for years but finally got in to precision shooting and things are not going very well here.

I recently bought a Savage 12 Bench Rest model in 6mm BR and I started the load development to find a good match but so far nothing, probably I'm too desperate or the lack of knowledge in this area is the issue.

I shoot only in an indoor range (so no wind) at 100 yards and I'm expecting from that rifle make a 3 shoots in 1 hole, that's my goal and I think the rifle should be capable (if not ill be so disappointed after spent all the money)

The first issue I found is that there is pretty much NO load data out there, the most I found is in the 6mmbr website but for some reason I always don't have all the right ingredients. I started with 68gr bullets and 70gr as well, so far I made 2 shots in the same hole and the third about 3" apart.

During my loading I'm sorting the brass which is Lapua by weight, im also sorting the bullets first by weight, and then by dimensions using the brownels 6mm collect and a caliper. Im using Redding competition dies, CCI BR primers, new brass, 264 bushing (I also tried 266 and 268 but the results are worst)

I even tried the Lapua 105gr ammo and nothing special, I can make a better group with my AR. I have a Sightron S3 10-50.

The rifle is 1-8 twist and I just bought Sierra Match King 107g, Nosler Comp 105g and Barnes 80gr Tipped TSX but the same thing, when I'm looking online for recipes, NOTHING.

I have the next powders in hand:
Reloader 15
Varget
IMR4064
Benchmark
H335
N135
N140

Now, how I should start the load development? because there is ton of adjustments which can make a difference, I stopped playing with the neck tension and im going to continue with different powders, different grains, but also there is different OAL, etc.

In a side note, I took the rifle out of the stock yesterday to adjust the trigger (best I can get is 8oz without any malfunction) and I found that all screws where finger tight (weird), but when im looking for info about that the opinions are all mixed, the Savage website says 30-35" pounds but I found many people in other forums saying just finger tight, so im not sure but im thinking that there's probably my issue.

I appreciate any help and any guidance of how to continue my load development.

Thanks in advance,

Angel

65 in pounds on the action screws will be right on, also your rifle should have a factory .272 no turn neck so a loaded round should be around .269 at the neck shoulder junction-.002 is .267 bushing
Be sure to torque your scope bases to 20 in pounds
Ensure your barrel is free floating
Once you've done that use a Hornday comparator to find your lands using 107 smk
Load Varget powder starting at 29.0 gr and perform a ladder test at .2 gr increments to 30. gr
Once you find your powder charge go to seating depth
If the Damn thing still won't shoot send it back

Edit- stick with one primer I use CCi br

Ask yourself another question - are you capable of doing this?

Working up a 100yd load from a solid bench in a tunnel should be fairly basic stuff. The fact your struggling makes me wonder if you have not set your expectations a little too high at this stage?

It might be your barrel but equally it could be were your currently at in your load development journey?

If you are getting 3” groups at 100 yards indoors, something is bad wrong.

The only thing that I saw in your description was what looked like too much neck tension. That doesn’t qualify as “bad wrong”. Hard to tell without being on the scene. We need to find you a mentor.

2 thou under the diameter of a loaded round should be good starting point.

I have a BVSS with a custom barrel and pillar bedded. Loaned it to a friend that was a 6 BR “flat earther”. He’s now a 6 BR fanatic.

87gr vmaxs 30.5 Varget cci450 primers shoot really good in one of my Savages. I have shot several 1 hole 5 shot groups with it when the stars align correctly. Under .5 and averaging .3 to .4 is what I fully expect.

3 inches out at 100 yards is a lots. My foulers after cleaning the barrel generally stay under an inch.

What does your Es look like on the shot that leaves the group? Is your brass loading consistent? I have found that some pieces of brass don’t shoot like the others. I cull them once I verify this and use them for foulers.

More than once while at the range, I'd see a fellow shooter going bat-shi* crazy trying to get his new Savage to make a group, and then finally realize that his action screws or scope mounts were loose. One guys action was so loose, when it picked it up, his action actually wobbled so much I thought it was about to fall out of the stock. A torque wrench is your friend here and it appears you have one. Good start!

Scope mount screws: Remove the front scope mount and install it with only the front screw torqued. Is the mount secure? If not, shorten the screw until it is secure as the screw is bottoming out against the barrel tenon threads.

Also check for clearance around the rear tang of the action. I run a .005 feeler gage between the tang and the stock. Sand to make clearance if necessary.

I hope this helps! Let us know what you do to get'r shooting dots.

You guys do realize this thread is from last year ?

With a factory made rifle you have no idea what you'll get. A 6 br is a very easy to tune round. After what You have tried, I would replace the barrel.

This, good advice.

I have that same rifle ' it shoots well.
