I'm just waiting to hear Seans point of view on the matter, before I offer my opinion. Cheers Ron

I am with Ron, lets wait and see what the rim fire expert has too say.

Ron will I see at Malabar on Saturday.

G'day Damian,

It's good to note the self professed academics of the shooting disciplines offer there wisdom.

My Anschutz started dropping shots and I have just corrected the problem. I found that the tension on both screws had slackened off somewhat.

As for torque wrenches-they are not needed all you need is the right sized screw driver-in fact an engineer will tell you this. If you are applying too much tension-to point where you think you are going to shit your pants or end up with a hernia then you are applying too much. You also need be very cautious as too much tension can bend the action.

Once you have adjusted the tension on the screws take the rifle and place it on the recoil pad-then tilt it over to a 45 degree angle in left and right hands-if you feel the action move in the stock then there is not enough tension. Once you have adjusted the tension then slide the bolt in and out of the action a few times. If you feel resistance (like that you have never felt previously) then you have more then likely applied too much tension. Finally you need tighten the screws in quarter turn increments and adjust both simultaneously-not one at a time.

As for barrels, I had Clancy rebarrel and fully true Leannes Bruno with a Lilja and chambered for R-50. I also have recently fitted it into a McMillan BR-50 stock, the rifle certainly shoots- but no better then my old Anschutz. What I have found is that 100 meters both my Model 4 Bruno and my Anschutz shoot tighter groups then the Customised Bruno. This is also replicated at 50 meters. I have also made these observations during windy days.

Above all-I am inclined to believe that the length of the barrel attributes significantly to accuracy.

If you are already shooting 200.15s then forget the barrel tuner. Concentrate on your technique and initial set-up.

Regards

<-- intends to keep the barrel tuner on the skinny lilja, which is shooting 200.20's and 200.19's

[native hunter]

I definitely think that if the rifle and ammo is up to scratch it's really a battle of technique and wind reading ability.!!
I must have the bug bad as its on my mind all the time, i find myself checking shoot calenders to see where i can turn up to next.

Barrel tuner all the way:

18/7 - 200.20
25/7 - 200.18
8/8 - 200.17
15/8 - 200.18
22/8 - 200.20
29/8 - 200.19

What's not to say about a proper barrel tuner!

Rebecca,

Is it the 'barrel-tuner' the quality of workmanship in the rifle or the time you take in reading the conditions before you squeeze off....?

Hi Sean,

I won't question the rest of your post, but I do have to disagree with this section of your comment.

Firstly because of the consistency of using a torque screwdriver. I've spent over 20 years as a fitter machinist, and I can guarantee that individuals gauge the torque they are applying very differently. I've managed to strip some fine threads in years gone by, and I know that the "stop one grunt before "Oh F*ck" method" is not a good standard. And on many other occassions I have had to helicoil threads where others have misjudged their own strength.

Secondly, the comment you made about "the right size screwdriver" is a "rule of thumb" statement, and while it may be correct in the majority of instances, it is not correct in all. You can easily strip a screw in an aluminium scope mount with the "right size screwdriver". And certain individuals have stronger wrists, like riders of old Harleys (Keith - where is that "sh;t-stirring" emoticon?).

Finally, you surprise me in your faith in engineers. I have met some great engineers that I would trust my life to. No problem. But I've met a very similar number who were total goobers that I would not trust with play dough. And others that were somewhere in between.
Hopefully the goobers eventually grow into great engineers or leave the arena. Perhaps this is how they evolve (Keith - we need a "sh;t-stirring" emoticon).

I use a torque screwdriver on a fairly regular basis to check the scope mounts and hold-down screws on my rifles. It is a quality unit, bought secondhand on ebay in 2009, for under $30. You'll be pleased to hear it came from the bankrupt aerospace industry in the home of capitalism across the pacific.

Does using a torque screwdriver improve my accuracy? Only by removing a cause of possible inaccuracy, and that cause might only be the doubt in my own mind.

Interesting question! I think it's all three, which is my point to Native Hunter.

I see a definite difference in the grouping of the same batch of ammo based on the barrel tuner setting. My old batch shot brilliantly with a setting I'm calling the "Initial Point" (there aren't any markings on my tuner...). The next batch I bought I had to wind out one complete turn to get it to group, and my current batch is shooting quite fine at a quarter turn out from the Initial Point.

Wind the tuner out two turns, and the group is bigger than the TRA 10-ring (so not good at all). Wind it out 1/2 turn from the Initial Point, and I get a group, but have a flyer.

Brett33 dropped a hint at the RBA Nationals that his setting was sensitive enough that only a few clicks would destroy the groups, which made me go back and look at 1/8th turns... arriving at my 1/4 turn out from the Initial Point.

Each batch is different, so now I'm getting anal about batches of eXact

[native hunter]

Oh dear-I dont buy enough x-act to have to worry about what batch i get,Wish i could though.!!
Im still using eley black thats working fine but I would say not perfect yet,as always its always an ammo chase.

Where's Rinso when ya need him!? I love his philosophy on the house brick and deck chair.

G'day Curan,

I certainly don't place complete faith in all the 'professionals' that I meet

I know what you mean about 'rule of thumb'. I also see it regularly out at Silverdale where newbies arrive with a rifle from Horsley Park that has not got enough tension on scope mounts or where they have applied Archimedes principle of leverage and used a 12 inch shifter and then wonder why they have stripped thread-I think it is relative to common sense.

I can understand the need for a torque wrench on a center fire, however, on a rim fire I personally believe that they are not needed.

Off hand whats the goin price for a brick of x-act.??I have been quoted $315 by one place and $340 by another.??
Native

[SnipeWench]

NH,

About that price. Just because it shoots ok in my rifle, doesn't mean that it will in yours.

You need to buy a box, shoot it, see whether it's grouping ok, then maybe play with the tuner to see whether you can improve on it. If it continues to shotgun, discount it as an option and move on.

Count your lucky stars if Eley Black shoots through yours - it's a helluva lot cheaper than eXact! Eley Black shoots great with my smallbore target rifle, so I use that (1069 I'm using at the moment, though think it's better shooting 1067).

Did ya know the number below the others on the box signifies the speed? You should test slower and faster speeds.

[juzz338]

Any idea what a box of federal 900 is would be worth these days?

[steven]

A box is worth nothing...a brick or case would be a different matter....if your selling a box don't worry about it just shoot it and get rid of it....if you have a brick or case then $15.00 a box would be reasonable.
