6.5x47 lapua reamer

[bulldog284]

Hello

I am building a 6.5x47 lapua I need a reamer the only bullet weight that I will be shooting are the 123 to the 130 burgers not interested to much in the 140
This rifle will be magazine fed so the over all length with a 130 Berger vld can't be over 2.850
Would like to know what the free bore should be? Any info would be very helpful

Would a .163 free bore be to long?I want to be able to touch the lands with the 130 and still feed threw the magazine

Thank you Darin

my freebore is .167 and I run 130 bergers with no problem tohching the lands and you can get full case capacity of powder but there are a lot with .120-.130 freebore and that will work too had a .110 and it still worked fine just had to a loooonnnggg drop tube for powder unless you don't mind crunching your powder. the 123 scenars will actually take up more case room than the bergers because of the difference in bearing surface than the bergers and my gun likes them better

My freebore is .175" and works well with 123's and 130's.

Thanks for the info what do you think a reasonable speed would be out of a 26 inch tube?

130 bergers I use 41.5 of H4350 and get 2920 but the scenars I use a little faster powder RL15 or varget 37-39 grains and 3000 is pretty easy to get to
