No I did not specify any chamber, its a Lowther Walther barrel and is being made to fit a Tikka T3 in .308.

My thinking was that a FLS case would be the same dimensions as a case from an unfired factory round!

No. Most definately not.

The unfired round will be made from brass that is smaller than SAAMI spec, ensuring it will fit in any chamber.

FLS will only take it back near to SAAMI, or on it, if you are lucky.

Brass work hardens, which is why we anneal the necks.

You can only push the webs back as far as the dies will allow, and sometimes that isn't enough to chamber the case.

Hi Baldy

Thanks for the help, I know you re an expert, just tried once fired FLS brass in new chamber and it fits without any resistance, so I reckon I had a bit of luck!

Regards

Redding

Thanks ds1, if they dont chamber after FLS it will be new brass

Only if you are going to progressively bump back from the existing fire formed size to get a fit.  A F/L sized case to SAAMI spec will fit unless a specifically tight chamber was requested  - in which case I'd have expected the poster to have sent a dummy round to the gunsmith as a gauge.

Erm yes, I used to Collet Die then shoulder die

Decided to go back to FLS

yes, just as if you've bought new brass

Ok thanks, theres a guy on Youtube called "the real gunsmith" that said you cant do it because every chamber is different and the brass has a memory, it just didnt make sense to me because if I full length size back to SAAMI its surely the same dimensions as new brass.

Thanks for the replies

I wanted to get the correct headspacing

So I return the brass to SAAMI spec and adjust the die for correct headspace after its been fireformed in the new chamber yes?

Collecting my re-barreled .308 tomorrow and have a question about brass.

I have a quantity of once fired Hornady brass, do I full length size it now in readiness or wait until I get the rifle back here?

Hornady are now using Doppler to calculate BC,s on some bullets and show G1, so the statement that G1 is for "Flat base bullets" is redundant I guess.

I keep seeing Ballistic Coefficients described in G1 & G7 figures.

If, as we are led to believe, G1 figures relate to flat based bullets then why do makers such as Hornady refer to the BC of their .308 155 gr. ELD Match bullet as 0.461 (G1) when it is patently a Boat-tailed bullet.  More annoying is they also quote a G7 BC of 0.232.

Just confuses the hell out of me.

I have 20 MOA rail +200clikcs from 100m,

220clikcs is limit in this model (after removing inside turret pin)

Got it, I rely heavily on the stop pin, but 100 clicks from 100 mtrs is plenty for me.

Not sure, I was replying from my phone, maybe thats got something to do with it

Having good optics alone doesn't cut it for me , There a lot of scopes better equiped than this out there for both the same money and less

Fine, thats your opinion and of course you are entitled to it

Do you mean 200 clicks from the 100 meter setting, or there are 200 clicks available from start to end with no stop pin in place?

If you mean 200 from 100m then without the pin in place that could theoretically get me out beyond 1000 meters! 

Only to get it back to zero after i fitted the 20 moa rail.

I have 101 clicks of elevation with the pin in place

Hey guys, actually the new V8 4,8-35x60 is not only limited with its 130cm of internal movement. It is even more limited with its 0,5cm clicks. The ASV LR has only 100clicks and this means that it has only 50cm of movement which equals 5MRAD... The guys at Zeiss are aware of this and they will probably release also the 1cm version with 10mrad of travel, but not for now.

I dont understand what you are saying here, my 4.8-35X60 V8 is zeroed at 100m and I have 101 clicks available from there, I have mounted it on a 20 moa rail though! 

I had the barrel on my CZ Style cut to 12" a few years ago, with a PH moddy its a dream to bash bunnys from the motor, 10 rounds of Win 40 grn subs cut a 3/4" hole in the target at 60 yards.

Go for it
