Great to hear the report Greg

I think if i remember rightly i was using a Barnard 07 in .260 cal 

You were 

one of the very first chassis rifles 

Oh how things have changed now 

Sadly it was 

Good times 

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 the pics and explanation re the contamination 

the pics of the chassis show some witness marks (tang area and around forward action screw hole 

There are also witness marks on the action in similar areas 

There doesn’t need to be any movement under recoil to create these marks 

It highlights my point that even inlets thy replicate certain actions are not 100% contact and will cause stress in an action when torqued down due to elasticity of the materials and the high forces generated (even at 50 inch pounds) that’s enough to bend the action or pull it out of shape 

This will have an adverse reaction to accuracy 

How much is dependant on where and how much movement there is in the action and it’s effect on contact surfaces of bolt lug : abutments : barrel tenon 

An example - last week I bedded a HS Prevision stock (alloy v block design in let) to a rifle I built two years ago, the rifle was put in a used pre bedded stock (bedded to another action) bought post build by the client - it shot sub half Moa in that stock

I had some pictures back yesterday of groups shot with the rifle in the stock I bedded 

Single hole, consistently repeatable groups 

That demonstrates the importance of mating the action to the inlet with bedding 

This isn’t the first time such improvements  have been highlighted 

The rifle in question is for deer work - I’d recommend anyone with a comp gun give thought to this simple but effective improvement to their chassis based “system”

@Catch-22 

Could you post a pic of the MPA action inlet (current) - intrigued to see if there are any witness marks showing on inlet or action base of the Inpact ,,,after several years of use in the chassis 

No

the Rem clones and Rem 700 are never a perfect all contact fit in any chassis including AiCS and any chassis that is “inlet for specific action”

One usually finds there is waterline contact along the length of the action on either side 

Appropriate skim bedding will address this though and provide stress free contact when action screws torqued 

7/300 WSM if you want to go 7mm

This cartridge has provenance in F Class to World Championship level and will get to a mile easily 

Though as Greg points out - spotting misses will be “problematic”

A stunner 

One of the best F Class stocks, period

Good luck with sale 👍🏻

PRC is magnum bolt face 

The ATX is only available in .473” bolt face 

You would have to use an A X MC but the short action cartridge may have issues feeding in this magazine 

Walters Rifleman produce a specific magazine to feed this and other short stubby cases 

I did say it was relatively easy if you followed the drawings 

well done 👍🏻

As it's an AE it won't have the changeable barrel 

Barrel is easily changed with clamp and action wrench 

I get why buy one - new shiny kit 

Also own LabRadar - Whixh works for me and is pretty portable 

But then so is my Magnetospeed and Oehler 35p (though the latter a faf to set up in comparison) 

👍🏻

So the UK warrantied units are selling or likely to sell at £530

yet people are buying from the states at 500 and incurring import duties and vat to the tune of over 100 

Non UK importer supplied units are not covered by warranty in this country and no doubt they will have serial number so easily verified 

Am I missing something as why it is sensible or even an intelligent option to buy outside the uk ?

What accuracy was it returning 

If you have the means then fly to Denver, hire car and head south to New Mexico and visit the Whittington Centre near Raton

This is the NRA largest range and has hosted KO2M in the past

I know you can hire weapons to use there

May be worth exploring

There are some places near Las Vegas that hire 50 cals but I’m not sure of how far one is able to shoot  

Well looked after too

Vectronix have announced a release of two new models of LRF Bino

Vector X and Radical X are the model names 

probably be the next must have on the  firing line,,,,

I do 😃

im, trying not to take work on because of that and balance out family , deer and target play rather than slaving at the wheel of death 24/7

plenty of folk now with a lathe starting up these days - only the dedicated will find me and get me to do work 😂😂

Also sourcing a suitable stock for the PChey is proving to be a bit of a quest - my main option is no longer available unfortunately (should have bought the chassis at the same time as the damn action) 

Manners, Dima and a spot in Oz that make chassis are on the list - Dima laminate looks most favourable 

this will now, no doubt be a 2025 evolution, though barrelled action will be done way before that. 
 

Not in a great rush as I’ve several big jobs on that are taking time at the mansion, which yet again is turning into a money pit 😂😂

Love to but rifke not ready yet

Love a 284
Mines currently a shehane although I don't see much improvement on my over the standard forming load overall to be honest with regard to velocity.

had a fox at 680M with the other week so it defiantly gets the job done with 180g elds,(ive not used 162s in this barrel but i get around 2800 with 180s

furniture changed but barrelled action looks familiar Andy 

👍🏻

Gents and ladies (depending how you identify) ,,,,

Please see the link to the 2024 calendar for the UK Rifle Series competitions 

These will be all held at Gardners Guns near Carlisle using the ranges there or at their Eskdalemuir complex 

Highly recommend participating, there are many members of the site who help and compete with these comps which are held in a very friendly atmosphere - no egos or b s usually ans lots of people with experience to help anyone who hasn’t been before and wants to try it out 

You don’t “need” anything other than a willing countenance, a zeroed rifle and an idea of your ballistic data 

Come and have a go and enjoy yourselves :
