MDT chassis back on sale due to issue with Parcelforce.

Can you tell me the width of these two Protektor bags and also the width for the forestocks they fit. Looking for a 3" and a 21/4" flat bag for rimfire benchrest. Thanks.

Yes really miss it good days we can never get back

So what exactly happened to the first barrel?

Original.

Sadly it was Good times

a chassis or an original stock ?

How much would you let one go for?

Just back from a weekend in Czech Republic with DS-1 on here . A fun weekend shooting the stuff we cant have in the UK . Instruction and guidance from Dave to improve but also a large helping of fun . pics to follow Czech tatical will be at the Harrogate show (as will we ) Strongly advise to treat yourself .....

Grey we have a few taken from rifles when fitting in our chassis

Was it really that long ago

I’m sure with a quality barrel - if fitted by a competent rifle smith you should be able to develop a load that returns single hole accuracy at calibre diameter or just slightly larger without resorting to a tuner You don’t say if the brass you’ve loaded is brand new or left overs from the old barrel If the new barrel was chambered and headspace’s to the same dimensions as the old barrel then it should fit The issue will be the bore diameter of the Bartlein will likely be different to the Sassen it replaced and if tighter land diameter will manifest in higher pressure something to bear in mind from the onset A tuner may help with a generic load but doesn’t replace good practice load development 👍🏻

Thanks for all the advice chaps.. The rifle is chambered in 6.5CM and I'm currently running 42g of RS62 with a 140g,bullet which from my research seems to be a very conservative load (2650fps), but it worked well so I'm hopeful this will be OK for the brake in process but I will load a few test rounds first and check the current load is safe, then after 100 or so rounds reassess the situation and see where i go from there.

That i did think of.. I made up a couple of dummy rounds and left them with the builder.

The first issue you have is one of safety, knowing for sure that the old ammo you have wont cause pressure in your new barrel. The second is will the old ammo fit the new chamber? I would load a few pressure testers up for the new barrel starting at least 2.0gr lower than your old ammo currently is and creep up to your old ammo charge weight and then beyond by another 1.0gr if possible. Go out and do a pressure test and if it reveals that your old charge weight is safe in the new gun then your safe to use the ammo assuming it fits the new chamber. If it doesnt then your pretty much scuppered without stripping that ammo and resizing it, whatever you do dont try to resize loaded ammo. As for a barrel tuner, if you have a good tuner than has been fitted/balanced by someone who knows what they are doing and they give you comprehensive instructions on how to use the tuner you might be able to improve the old load should it not shoot so well in the new barrel. My experience is tuners will tune any load so some degree, even bad loads. A well balanced tuner can usually half group sizes from worst case scenario. By that I mean if you keep adjusting the tuner until the groups are the largest then with correct tuning they will go to about half the worst group size, so 2" down to 1" or 0.5" down to 0.25" if you have a good barrel and load combo. Ive seen so many examples of this with both home loads and factory ammo Im confident in what I say. If when the tuner has been fitted by coincidence an optimum is reached before moving the tuner then all moving it will do is increase group sizes then bring them back to where they started again. The biggest issue I have found though regarding tuners is actually getting one that is the right weight for the barrel and that has the right level of adjustment in terms of thread pitch and increment size to give you half a chance of it being useful. Long thin barrels have different requirements to short fat barrels, the same tuner wont work the same on each. As I see things now its a bit pot luck with tuners because nobody Im aware of has made different spec (weight) tuners to work with different barrel profiles and there is very little published info that is any use to allow users to get the best from the tuner assuming its the right spec for the barrel. The same weight tuner could work across all barrel specs but it would need to be treat very differently on a stiff barrel to a flimsy one. If I was going to produce barrel tuners for general sale I would probably make at least three different weights to cover the spectrum of CF barrels out there from hunting to competition and again a couple of different ones for rimfire, its definitely not an easy one size fits all thing. A lot of the tuners out there are just far too heavy and as a result the adjustments are too coarse often creating POI shifts rather than shifts in tune, I think this explains why many people have been sceptical because they havent been able to get the best from the barrel with the wrong type of tuner fitted and very poor instructions for use. If nothing else and you dont use a tuner then if your old ammo is safe to use you can use it to run the new barrel in. Every new barrel needs to be run in but not for the reasons many think. For me running the barrel in has nothing to do with extending its lifespan or improving its accuracy. Every barrel Ive ever chrono'd from new (of which there are many) has always sped up by anywhere from 80-150fps after around 100-150 shots. If you develop a load for a new barrel before it stops speeding up then your tune will shift as your speed does. Thats why diligent competition shooters dont develop a load for a new barrel until it has stopped speeding up. Of course this only matters when looking for optimum accuracy, many people just require acceptable accuracy which can be very different from optimum.

The chambers vary and the ammo that fitted the old chamber may not fit in the new one

Designed for long range prone shooting. Handles recoil very well.

Not barrel action ,trigger or the scope Thank you

Thanks, lets just hope 42grains is perfect! incidentally Old barrel was a Sasson is now a Bartlien.

It's a controversial subject, some say "works a treat", some say "snake oil" and then views in-between. Barrel break-in is another subjective view, at least for a quality target barrel like Sasson or Bartlien. 😑

A Barrel Tuner can tweak a good load, but it won't turn a bad load into a tack driver.

I'm picking up my rifle tomorrow after its had a new barrel fitted. The old barrel went south pretty quickly, ( operator error and old age it turns out), so my problem might be I have 500 rounds of identical hand made rounds ready and waiting, what if my new barrel doesn't like the load? Can you use a barrel tuner to tune a barrel to a specific load, or if the 2 aren't a match do I have to pull all the bullets and start again? (obviously I give the barrel a chance to break in first)
