Optimum .308 barrel length

[redding]

Well I've been & done it

Mr Norris has cut my Sauer .308 down to 18" (I asked him to by the way!)

It had a 23" 1-12 twist factory barrel and was producing 2832 fps with 150 grn Speer SPBT/47 grns of Varget & a 9 1/2 Rem primer in Winchester brass, giving me a thumbnail group at 100yards (technical eh)

 

Tomorrow is test day, I have some rounds left from the above batch and it'll be interesting to see what the velocity drop is before I develop anything else.

 

Needless to say the workmanship is awesome, a new thread, an 11 degree target crown and a thread protector to die for.

 

If you read this Mike, I want one of those "Contractor" Ratels ok.

 

Update: Based on the chrony average velocity over 6 rounds of 2682 fps, the toal velocity loss is 150 fps (37.5 fps per inch) I can live with that.

Now going to buy an Atec Maxim to replace the 1 month old Spartan which will be for sale as soon as I get it.
