This is the only one I've seen - I made this collet clamp to use a tuner and a moderator as I didn't want to jump straight in and screwcut my shiny new lilja match barrel. This is on a rimfire, not sure I would want a clamp on one on a centrefire.

Nice work was it successfully?

The muzzle brake needs to stay in the orientation its currently in to work properly, you dont want gases exiting downwards or it will cover you in dust and also try to lift the muzzle of the ground when shooting prone. Thats the reason there is a tuner fitted behind it. Also the muzzle brake is too heavy and has no means of making small accurate and repeatable movements which a good tuner needs to be able to do.

I did use a pepper pot muzzle brake as a tuner once, that worked but it had the correct thread and the nylon tipped set screws and fine increments so it was very much a tuner with a brake incorporated.

 

Yes I thought that would be the case , works in principle but not practice to a fine enough degree. 

Is there one on the market that will allow a moderator without machining the barrel eg clamp on.

No, the EC tuner and indeed most of the other designs use nylon tipped grub screws to control the friction on the thread.

Sorry what I meant was could the compensator be used as a tuner as it can be set at different distances using the lock nut although you couldn't fine tune obviously

Your looking too deeply BD.

I think both myself and Alan have already said it doesnt matter where exactly the tuner is placed, it just means more or less weight shift needs to occur to get the same results. The EC tuner is popular but personally I think its too heavy in combination with the thread making for too coarse adjustments.

I fitted one recently and also shortened it by about 40% to bring the weight down to work better with the thread that we have to work with. This ives better control of the incremental adjustments and you can see more of whats going on. There are other aspects of the design I dont like as well as its weight to thread pitch ratio but its not a thread about whats wrong with the EC tuner so I will keep them to myself.

Ive had tuners in front and behind the crown and also mid barrel, they have all worked as good as each other but required different amounts of weight to get the job done. Mid barrel is pointless it just adds too much weight and looks ugly. Around the muzzle is the right place.

I am guessing that the compensator has a locking nut to get the orientation correct wouldn't that have the same affect as a tuner or isn't there enough mass to it?

As I am still doing load development for my 308 I will start with experimenting with my .22 Tikka T1x with the  mod and shim washers just for the hell of it. 

But first I will put it in my Oryx chassis I have just ordered.

lots of different things out there, I’ve seen the Limbsave put in barrels and moved about, and groups of O seal at different locations on barrels while trying to play with harmonics.

With BPCR,s you can put talc along the top of the barrel and ‘ring it’ to determine where to rest on your cross sticks.

Do not think you can categorically say one thing is better than another as a lot of stuff out there is anecdotal. As Al points out sometimes what can be tried is limited by a class restriction. Believe when folks went over to heavy adjustable ladders on TR foresight’s they saw a difference - but that was rumoured 🤔. 

Have a play, nothing to loose. I can say that a 22rf does benefit by putting ‘something on its nose’ that can be adjusted

Joe Myers gun with Limbsaver and heavy adjustable tuner, think he is current 22rf. Record holder

That is one beast of a rifle

A barrel tuner needs to be able to make precise and repeatable movements, the Limbsaver thing doesnt offer that.

I didn't think it would be up to the task. 

Is there one where you can still use the moderator and the barrel doesn't need to be machined

Have you tried the limbsaver rubber thing as I would like to use the  moderator with it 

Thanks for replies I think I will give some  shim washers a try, could be a fun experiment 

This may sound like a strange questions but could you tune a barrel using the moderator. 

My thoughts are that a tuner is basically a weight that can be adjusted by sometimes a very small amount to improve barrel harmonics so could you do the same with a moderator using different thickness washers as spacers or as usual am I living in cuckoo land.

I have a jet z compact mod

Unfortunately not, I made this as a "one off" for experiments. 

Fair enough.

here you go, http://www.ezellcustomrifles.com/home-3/pdt-tuners/

just a different approach to barrel tuners

March Scopes UK have them if you’re interested? Not sure who keeps Harrell’s?

Thank you,  very interesting

put a Harrels on a Annie MPR, used the Purdey method to start with . Found it produced more ‘round’ groups in an already accurate rifle. Does take a bit of setting up initially

As stated you find the make of ammo your rifle liked then improve on that.

Will be fitting a particle damper on the new 22rf build.

Forgive my lack of knowledge but what is a particle damper

Yes, had a play with tuners. I would really like to do some proper testing at 50/100 yards in a tunnel range, unfortunately nothing locally available. Yes, tuners do definitely have an effect, I'm really surprised they have not really caught on over here. In the US 95% of all .22lr benchrest shooters use them.

This is one I designed to fit between the barrel and moderator.:

 

 

That looks interesting are they available to purchase 

Hello all

Has anyone tried a barrel tuner on a rimfire rifle. 

Just thinking that as with most if not all rimfire rifles they have there favourite ammo, so what if you have a preferred ammo that doesn't shoot the best in your rifle,  would a tuner improve your groups

A lot of custom second hand rifles are available at approx 1500-1650 range that are well worth that, costing much much more to buy new 

a sightron 8-32 would take up the remainder giving a world class setup and practise while you kill that barrel. Once the barrel is shot out, rebarrel in exactly what they want and not loose any money 

 

That is a very good way of looking at it as a rebarrel would be a lot cheaper than a new rifle especially if it fit you well.

Thank you for all the info I shall pass it on and it will give him an Idea to research

I have a.308 that I am doing load development for at the moment but this is for a chap I know that is looking to join our club was asking so rather than just give him my opinion I thought opening it up to people that know more than me would be wise .

His budget is around 2k including scope and range is 100 yards at our club to start with then up to 500-600 later on.

This will be his first full bore rifle.

He might reload in the future if he gets hooked which I bet he will but it will be factory ammo to start with.

6br Savage, reloading is a doddle in my own opinion. 90 gn up to 600 yards or 105 gn up to 10000 yards.

If your a member of a club, try to use a rifle before you buy. 

Thanks nick 

 

 

What would barrel life be like for the 6br

55 minutes ago, Popsbengo said:

.223 or .308 all day long.  Endless combinations of reloading components, cheap and plentiful factory ammo.  If you can afford it,  6.5 Creedmore is  clearly more accurate but at 600 yds it's easy enough to expect 1moa or better from .308 and .223

I was thinking .223 could be in the running and I guess barrel life should be fairly good.

So another question if I were to use factory ammo only could a barrel tuner improve grouping, thinking of tuning the rifle to the ammo instead of the ammo to the rifle

If you had to start from scratch which calibre would you use for target shooting out to 600.

To include ease of reloading and availablity of reasonable factory ammo.

Was looking for a long range rifle but a lesser calibre than Lapmag .I am a lefty but given that I shoot from fixed positions with my long range kit a right handed rifle is not an issue......I looked around for a few weeks to see what was on offer as I really couldn’t be bothered with the cost and hassle of getting one built.....My final choice was the Sabatti Evo tactical in 300 win mag and to date I have no regrets ...Well made ,well priced and sub .5 moa is a winner for me.Stock is adjustable and seems fine for me .Is anybody having problems with their stocks ?

I don't think I am having trouble yet as I am doing load development so I am not sure if it is the load or stock, I am just looking into options for the future

Mark, bedding into a plastic stock is not the greatest. Often difficult to bond depending on what material the stock is actually made of. I have not heard of Redux nor used it. If it is an adhesive it might have different properties than actually wanted as a bedding material. Bedding compounds should be highly filled with metals, minerals and fibers.

edi

 

I may try to find a chassis that works but as it's a slightly unusual rifle I am not sure how much luck I will have.

I will finish the load development first and if I am not happy I will then look at options but thank you all for your input it gives me an idea where to start

Mark,

I personally like grey MarineTex after trying if from recommendation by a known US Gunsmith (and it turns out a couple of good UK ones), it is what the US Marines use (nothing to do with the 'Marine' in MarineTex) when they build rifles.

Have found it very nice to work with, consistency of clotted cream, not too bad to clean up. , does come in small 'one stocks worth' pack sizes - Unfortunately not always easy to obtain in the UK

Here's an article by Speedy Gonzales who's quite a recognised US gunsmith on the merits of different bedding materials:  http://bulletin.accurateshooter.com/2019/01/bed-it-right-bedding-compounds-compared-by-speedy/

Thank you I will take a look

I don't think one will go far wrong with Devcon, they normally have good products. We have bedded well over 500 stocks in the last years but would not use any of the normal bedding compounds. We blend our own bedding compounds using aerospace approved epoxy systems which lead to several advantages. OK if all bits are at hand however for the odd bedding devcon etc is easier.

edi

I used to work in aerospace and we used a compound called redux and I was wandering if it would work.

It is a structural adhesive which looks like lemon curd before you mix it

I think most would agree that either Devcon or MarineTex would be the best option for bedding. More so than glass bedding.

I‘ve read numerous comments, articles etc by people discussing Devcon vs MarineTex. Seemingly people prefer one over the other and quote multiple reasons for their assertion. I’m not sure if I’ve come across a definitive study that shows one is better than the other though.

To my mind, it sort of depends on what your chosen ‘applicator’ thinks and feels is best, given their experience of bedding xxx number of stocks.

Thank you I will take a look at both of them, I am planning to do it myself.

Cheers Mark
