Bambi-basher Posted June 20, 2011 Report Share Posted June 20, 2011 Hi Chaps I have a Browning A-Bolt that I am thinking of re-barrelling with a 1-8 twist Walther barrel. The rifle is a mini-mauser length action, so I can’t use a 308 based case so a 6X47 is a no no, at the minute it is a 243 WSSM while I don’t have a problem with that I was thinking of going to a 6mm Dasher. Because the rifle is used with a moderator and always will, (I have enough hearing damage as it is,) I want to keep the barrel as short as possible, 20” maybe 22” max. All the velocity figures I am seeing are quoting long target barrels, I want to run it on 105s and really need 2850fps to keep it big deer legal for up here in Scotland. I know some of you guys have had Dashers but what velocity could I expect with a short barrel? My second concern is the primer, I have read recently of problems when using a bolt which was originally made for a large primer, but then re-chambered to a small primer calibre. Now this is not a big problem as I can sleeve the primer hole in the bolt head and turn down the firing pin myself but the question is, is this necessary?

Scotch_egg Posted June 21, 2011 Report Share Posted June 21, 2011 The 6.5x47 isn't as big as a .308 would it be worth getting hold of a piece of brass and seeing if it would fit in your mag? I'm not sure how well a dasher would mag feed with improved shoulders. Link to comment Share on other sites More sharing options...
Bambi-basher Posted June 21, 2011 Author Report Share Posted June 21, 2011 Hi S.E. I have been there and done that, a 6.5X47 case will not fit in the action I have tried it, also I don’t want a 6.5 cal’ I want a 6mm. It will be using a custom magazine feeding from the central position; I have the WSSM feeding reliably so I will hopefully get the Dasher to do so also.

Scotch_egg Posted June 21, 2011 Report Share Posted June 21, 2011 Only reason I said 6.5x47 was because it would have been pretty much the same dimension as the 6-6.5x47 shame it won't fit. I hope some one can help with the dasher ballistics. Link to comment Share on other sites More sharing options...
Bambi-basher Posted June 21, 2011 Author Report Share Posted June 21, 2011 Yeh it was the first thing I tried, the other thing is I have a 6.5X47 coming to my cabinet anyway, although this will be a heavy barreled model were the A-Bolt is a light stalking rifle.

Scotch_egg Posted June 21, 2011 Report Share Posted June 21, 2011 Just done a bit of googling and found this topic. Half way down a BRX is mentioned out of a 22" barrel achieving over 3000fps with a 107gr SMK http://forum.accurateshooter.com/index.php?topic=3746685.0 I recon the dasher would do the job.

Bambi-basher Posted June 23, 2011 Author Report Share Posted June 23, 2011 Thanks for that Dave I guess I could chamber it for the Dasher and if it didn't work out rechamber it for the WSSM. ATB B-b Link to comment Share on other sites More sharing options...

Cheers Andy nice one Andy. i love the br but i use it for long range foxing with a 70 gr pill, and the 100s for deer, the 20 tac is the tool of choice for the moment, i also still have the 17hmr but would like to sell it for a fireball i have in the planning with neil. sadly i too have a nice 22lr, but it will never see the light of day on bunnies, just to far away now for the wee 22lr. to help Link to comment Share on other sites More sharing options...
