Hi Sam,
First of well done, great story, and good pictures to go along with it. I’m interested in how this rifle is bedded,and could you elaborate further.
Good shooting!

The reason behind the 29.5 inch barrel was: for one that was all length we could get out of the blank. Two, if I ever shot the barrel out I could cut a few inches off and still have, say, a 26 inch barrel. The length had nothing to do with accuracy in my opinion. I have wondered myself if a shorter stiffer barrel is more accurate. I have not seen this in the longrange game. I have shot 6 Dashers with 25.5 to 32 inch barrels, and in between, and got each to shoot extremely well. What is more important than length is to fine tune the load to the barrel. For instance, if I took the 32 inch barrel that shoots very well with a load I tuned and cut 2 inches off of it, I will bet it would not shoot that same load as well as it did before. I would have to re-tune the load to the barrel. I guess this is where harmonics come to play. Hope this answers your question. Samuel Hall

To answer the question about barrel length. I have tried different barrel lengths in a 6MM Dasher, from 25.5 to 32 inches and in between. Fact is they all shot good. You just have to tune for every barrel and barrel length. Now if I took my 32 inch barrel and cut 2 inches off of it, more than likely I would have to completely retune the barrel.
The only reason I went with 29.5 inches on this barrel was that was all the length we could get out of the blank. When I shoot it out I could cut off 3.5 inches or so off the chamber end and still have a 26 inch barrel.

Robert,
I had made a mistake when I wrote down the primer I was using. I used a CCI-BR-4 also, not a CCI-450.

Currently building a 6.5×47 to launch JLK 130 VLDs for F-Class. I was thinking of using RL15 in similar loads. Can you share the thinking behind the 29.5″ barrel?

It’s interesting because when I did a fair amount of work with the 6.5 x 47 Lapua, my final load for 600 yards was 37 gr of RL15 with the 123 Scenar bullet and a CCI BR-4 primer, and I was running a 30″ long 8.5″ twist Brux barrel too. That load in that barrel always shot very well for me.
