Brillo Posted September 13, 2016 Report Share Posted September 13, 2016 Here's a question for the 'smiths' on here. If I shortened my rifle by one or two inches, How much weight would I lose per inch from the muzzle? It's currently 0.95" or thereabouts. Link to comment Share on other sites More sharing options...
The Gun Pimp Posted September 13, 2016 Report Share Posted September 13, 2016 About 4 oz per inch. Link to comment Share on other sites More sharing options...

The_Dogge Posted September 13, 2016 Report Share Posted September 13, 2016 Pretty simple maths, calculate the volume of the barrel: Pi * r^2 * L Take away the volume of the bore (you didn't specify the calibre) multiply by the density of steel (google says 7750kg/m^3, it does vary significantly with the type of steel) I make it 85g/inch assuming .22" bore (3Oz), a bigger bore will obviously reduce this weight.

Brillo Posted September 13, 2016 Author Report Share Posted September 13, 2016 It's a .308. I think I'll go with the 'about 4 oz per inch' Link to comment Share on other sites More sharing options...
Brillo Posted September 13, 2016 Author Report Share Posted September 13, 2016 Taking the straight taper into account and the equation above I make it 91g (3.12 oz) for the first inch. Link to comment Share on other sites More sharing options...
justin credible Posted September 13, 2016 Report Share Posted September 13, 2016 That'll do then mate, you won't need to take half your stock off to get underweight next time then:)) Link to comment Share on other sites More sharing options...
The_Dogge Posted September 13, 2016 Report Share Posted September 13, 2016 I just remembered there's a spreadsheet for this at http://www.jacksonrifles.com/articles.htm if you want to be accurate with tapered barrels. Link to comment Share on other sites More sharing options...

furrybean Posted September 13, 2016 Report Share Posted September 13, 2016 Can't remember but I was on the last 1000 yard detail and got piss wet through lol Link to comment Share on other sites More sharing options...
justin credible Posted September 13, 2016 Report Share Posted September 13, 2016 Lol ah that was you. Good effort shooting like that matey!! Mark shot better using the "head levitation technique" than he did using the conventional "head on stock technique" I'm going to give it a try next time cos I couldn't hit a barn door.

"Head levitation technique" - love it. Furrybean, I was on that detail too, on Tgt 48. What a contrast to the following day. Still, it was an enjoyable event.

furrybean Posted September 14, 2016 Report Share Posted September 14, 2016 How much weight do you normally loose with fluting? Link to comment Share on other sites More sharing options...
Brillo Posted September 14, 2016 Author Report Share Posted September 14, 2016 How much weight do you normally loose with fluting? According to the Victrix catalogue, a Benchmark 32" barrel fluted barrel is 500g lighter than a non-fluted. Obviously, this would be slightly different for other makes and profiles but it's good ball-park figure. Link to comment Share on other sites More sharing options...
