i'm having a new rifle built and i'm having a tough time deciding on which caliber to have built. its between a 22 dasher and a 22-250AI. does anyone have any pros/cons on these two calibers? i'm wanting to shoot both heavy and lighter bullets (52 gr). the barrel has already been ordered with a 1 in 8 twist.
thanks

it will be mostly used for varmints. i don't do many compititions but i do spend a lot of time with my rifles trying to get the best groups i can so i want a rifle that will shoot very consistantly yet has enough speed for varmints.

Having used both of these rounds as well as the .243AI, .220 Swift and a bunch of others "similar" let me state that the small primer pocket of the DASher round offers an enormous pressure advantage to the DASher case over others using the large primer.

Either the 6BR case or the new 6.5X47case will absolutely SMOKE any any .22cal based on 22-250/.243/.257/.220 brass or any similar variant............ all variants based on tough Lapua brass.

The .22DASher is a truly inspired round. Remember to have your reamer sized and your rifle chambered in such a way that you can set your crush-fit fireforming HEADSPACE when you neck down to .22 and that the resultant GAP SPACE will be acceptable. I like the Gapspace to be such that you must trim ALL of the cases to just fit the chamber for OAL fior fireforming and then you RE-TRIM for a couple thou clearance after your first fireform. This will result in a gapspace of less than 5 thou for cleanliness' sake.

The .22 DASher is a much more logical choice, or at least an easier round to make than the so-called "6 Dasher". I'll lean heavily towards it. I will never again spend money on a large primer pocket 22/6mm round. They ALL suck.

thanks for the info and it sounds like the dasher would be a fun cartridge. when i get closer to having it chambered would you mind if i asked a few more questions on the subject?

Absolutely! :)

This IS where the answers may be found BUT.......Since this isn't a competitive round for short range centerfire BR may I suggest that the questions be asked over on the Factory/Hybrid board :)

This round is perfectly suited for discussion there.

Getting this chambering RIGHT is not simple. There are tons of "dasher" variants out there and few who really understand them. The .22 variant as designed by Dowling and Ashton is really a well thought out gem. It'll pay big dividends to do your research. A search of "Dowling", "Dan Dowling" and .22 DASher will probably turn up some interesting info also.

See ya' over on the other board soon ;)
