6mm Dasher project

I had a 6mm Swiss match for a while, basically the same cartridge as your 6-6.5x47. Very accurate and easy to load case. I was using the 115 DTAC,s from memory.

Chose the 6mm Dasher as I wanted a pure accurate range rifle. 2900+ is all I was looking for with the 105’s which my rifle is easily achieving with the 4166. My gut feeling is there is another load a bit faster than the 2940fps but it is not necessary.

Out of interest what speed were you looking for?

Thibben,

I wasn't being greedy, 2900 - 3000fps or thereabouts would have been acceptable, subject to accuracy, but I couldn't achieve 2800fps without ejector marks on the brass, two different bullets and three different powders didn't make any difference, must have just been a 'slow' barrel. It did and does shoot accurately enough for my needs, short and mid range F class, but you are potentially leaving too many points on the table at those low speeds when your competitors are shooting 7mm cartridges!
