Got a 24in Blaser tactical 2 rifle chambered in 308, and according to the manual, it is 1 in 11'' twist rate.
Could you guys please give me some suggestions for the reloading data? I tried some hornady 178 eld-x, the grouping at 200 yards is not very stable, 100 yards is better.
I'm using 42.4-grain varget powder.
My friend told me that sierra 175 tmk is better for 1 in 11 rates.
Also, do you guys have any suggestion for the power measurement tools? I'm using Lyman gen6 compact dispenser, I do not think its very accurate.
Thanks

Berger vld hunting or sierra match kings in the 168 flavor, 2.800 COAL with varget or imr 4064 in whatever brass with federal 210m primers. Ive also heard that H4895 works wonders too, although i have yet to try it.

Thank you, I'm currently using GM215M primers...
 
A 1:11 will stabalize ordinary match bullets up to 200 gr very well.

Unless you go to 200+ gr extreme VLD bullets, twist will have nothing to do with your accuracy results.

Is the action bedded? No accuracy unless it is.

Is forend free floating?

Can you shoot?

I would not use a 215M primer in a 308 with Varget or 4895.

I believed it is bedded, according to the instruction manual, only need to hand tight the 2 Botha that holding the barrel and stock together.
I think it’s free floating, attached the picture. View attachment 286430
I can pull the trigger if that’s what you asked.
Different resources says 215m is fine, especially in the cold weather condition.
Rah is you
 
You are getting advice from some very experienced shooters, I suggest you recognize that. As stated, your rifle will stabilize pretty well anything under 200 gr. However, just because a bullet is stabilized doesnt mean it will give accuracy - you should bone up on barrel harmonics. Your rifle will likely tune to a particular bullet weight, so you need to try weights from 150 to 178 to get the best results.
Oh, there is more to shooting than pulling the trigger. If you are a novice shooter consider yourself lucky to get 1.5 to 2 moa. And finally, the torque you apply to the action screws can affect your results, hopefully "hand tight" translates into a repeatable 35-45 inch pounds.

Don't take offense but considering I do not know you or how you shoot, I would suggest you buy some federal gold match 168gr&175gr and post some 100m groups. This will give us some base of what your rifle is capable and more importantly what you are capable.

This will save you/us a lot of frustration.

Thank you sir. I do not have any problem with factory rounds, put through couple boxes of 168 and 178gr federal gold match, the grouping is tight enough for me. That is why I would like some reloading data...
this is 168 and 178 at 100 yards, not much difference, guess its only 100 yardsView attachment 286489View attachment 286490
And here is my handload, at 100 yardsView attachment 286491
And this is 42.4 gr varget with 178 eld-x hornady at 200 yards..I'm not very impressed with this.View attachment 286492
 
My friend has got a 24’’ 1:11 remington with benchmark barrel while i use a 26’’ 1:10 savage with an IBI barrel,
We both got impressive results out to 600M with this, i can sub 1/2 moa a 10 shot group at 300M.
We are both running a 175 SMK going at 2700fps (so we use 1 set of drop data for both rifles, was not intended but ended up that way and we have proven that our drops are both the same to 900M, with repeatability).
Both are using CCI BR2 primers, as Ganderite has mentioned my readings have steered me away from Fed 205M for Varget and 308 (it would “seem” that CCI is the solution here),

My 26’’ needs 42.7gn of varget to hit 2700fps,
His 24’’ needs 44.5gn of varget to hit 2700fps

Edit : i would still specifically torque the action screws, so that there is repeatability if you should dissassemble and reassemble rifle.
Once again both our settings are at 65in/lbs,
But we are also both using MDT chassis, the stock dictates the torque i would believe, i only followed the instructions

Thank you, sir, I appreciate your data.
 
From your targets, its pretty obvious that your rifle prefers the 175 Sierras over the Hornady 168 and 178's, so stick with the Sierras - those are pretty good groups. I would suggest that you may be the limiting factor with the Sierras, it may be difficult to get better results by load tuning. One thing you can focus on is consistency from round to round when reloading - things like brass type and preparation.
And, as a novice, you will find it is a harder to shoot 1 moa at 200 y, compared to 100 y. That's what practice is all about... BTW - you chose an inferior load to go out to 200 y, but didn't do too bad. You shot 2 moa at 100, and 1.8 moa at 200.

No problem.
Just re-read your first post, you we're also asking about powdering, my best groups we're not possible before i got my new scale 1.5 years ago (was previously using RCBS chargemaster which wasn't much accurate).
Look on autotrickler.com , and get the FX120 with auto-throw and auto-trickle, this will have you set for consistent powder charges.
Some say you can achieve same results for less, but this setup makes powdering precision ammo a quick job,
There is a price tag to it, but since you are shooting a blaser topped with a spuhred S&B on your pictures, i do not think the price tag will steer you away as it's not that expensive.

Thanks, I checked out their website, looks pretty promising, but wonder why they charging USD while they are actually based in Canada, lol
 
I agree with you it's close to stupid to charge USD for a CDN product, almost a way of increasing margin...
But! The product is worth getting over that fact and just buy it.

The kick in the balls is that he actually charges Canadian tax in U.S dollars.... feels extra shady.

Are you using Lapua brass?
 
I’m with cosmic, your target is telling you that the gun prefers the Sierra, and you chose to shoot the hornady which was dismal @100 farther out?
