with kindest regards,

back on thread (and i apologise for my lighthearted diversion) this does look like a great rifle not my cup of tea but being an engineer i appreciate the design.
Thank you

Dougan you ask a very valid question. I can only refer to the FTR environment where I am a newbie still but bear with my conceptual thoughts and musings
Barrel Length decisions affect several elements
Profile :
Affects WEIGHT and ACCURACY : The thickness, shape and overall length will affect the Deflection of a barrel and define the theoretical nominal accuracy for a given barrel.
http://www.riflebarrels.com/articles/ba ... rifles.htm
Twist
To ensure optimal stability of the bullet in defined conditions for intended shooting distances (Miller of 1.4 plus)
Throat
Presuming a ideal throat / lands combinations to maximise tuning and powder charge
In a perfect world it would be ideal to have ONE base chassis setup for oneself:
Scope - eye relief
Trigger
Chassis length of pull
Cheekpiece setup
Alternates in say 1:13 for 155 x's
1. 300 - 600 : 26 inch barrel rigid and focussed on accuracy
2. 600 plus you have a 30-32 inch barrel that you can maximise velocity for wind drift versus accuracy
3. 3rd 1:11 barrel in 30-32 for say 185 g X bullets in case of extreme winds
You swop out in literally 45 to 60 seconds whilst talking "poppycock" with your fellow shooters
No headspace issues
No Setup issue
:goodjob:
In "normal" terms - you would have had to have 3 full guns + scopes
OR
Need 30 minutes to swop barrels / check headspace etc.
What is their NOT to like!
Arh!, this is interesting...so it's not just about different calibers, you can have different barrels of the same caliber but with different length and twist for different bullets, distances and conditions...hadn't thought of that!
...the only downside I can see now, is that with all those variations (including caliber), it'd be hard deciding on which barrels you want....
...although if I could afford it, it'd be fun trying

Um......... any idea how much a basic mod 75 (no sights, but with Palma spec barrel) in .308 is likely to cost? (the nearest hundred will do)
H/man
I do believe the quality is remembered long after the tears over the price have dried..................

Hauptman, would this be for TR, if so it would need the hand cup, this is basically an extra fitting that both increases the lower diameter of the forend and adds a location for a standard rail fitting hand stop and sling attachment to be attached.

Yes, TR and MR (barrel weight< 2.5kgs).

I have an order for some actions coming in and can add a barrel, I will check on available profiles and PM you on this.

Any progress and photos of the 75 & 66 yet?
I've got a spare slot

The first run of M75 chassis systems are built and already spoken for and we are currently working on some minor design changes such as the elevation control for the rear bag rider option and other minor tweaks on the back end. I suspect will need to kick off a second run of M75 chassis very shortly.
The M66 chassis are built with the exception of the receivers which we should start in the next 7-10 days, we just need to decide on how many to build, these will be both target and repeater systems. The repeater using the AICS magazines.
The LMT and LMR receivers are all built, 12 of each and once they are back from vapour honing, anodising and laser etching I will put them together.
Everything is progressing at quite a rate now and considering they are not advertised anywhere people certainly seem to know about them and want to order them tongueout

David,
As you have the 75 elements at hand, you can perhaps show our friends a picture of the 75 'in the white'?

Good idea Robert, the parts are due to head off for vapour honing and type 3 black anodising/laser etching shortly however I can take a picture or two of the M75 chassis system in the white so people can see what it looks now.
I will haul a camera out in a bit.
