Why aren't there more of these around? The 22BR doesn't have as much velocity as the dasher of course but can still send the 90's about 3050-3100. The dasher shooting 90grn VLD's has better ballistics than any 6mm or 308. The only thing that beats it are 6.5mm from 140grn+ and the 7mm.

Lower recoil, lower reloading costs, better ballistics. So? Anyone?
 
the 90's have not been around that long. There is also the issue of having to re-size your brass. The Big issue though, is just like the 180 Berger: There is only one real bullet choice. If your gun don't like 'em, it don't like em. Building a gun for one bullet is a risk. The SMK is close, but it isn't a 90 berger.

Having said that, there are MANY of them around. There are two guys in my club that use them and do very very well with them. Unfortunately, the overwhelming majority of competitive precision shooters have no use for this forum and thus you never hear from them. There are only 3 of 20 really active F-Class guys at our club that are on here.
 
I shoot a 22BR and it is very accurate but I am only shooting at approx 2950 fps. This load is so scary accurate that I haven't explored any accuracy nodes at the higher velocities because for me the wind drift advantage isn't significant and I would prefer to run at the lower pressures. BTW, the Sierra 90 is built for 223 velocities and will blow up at the 3100 fps levels. In my rifles, the Berger VLD is more accurate tha the 90 BT's. IMHO, if you need more speed use more case capacity. I been thinking of playing with a 22-47 Lapua. Steve
 
Max,

I am wondering about the 22 Dasher,, who's gun is a 22 Dasher,, a guy at gun at your range or his brother, in Edmonton??

Thanx NN

Well, I do need to get out more. It just seems like every man and his dog talk about their 6BR's, you just never hear too much about these. I agree it is a little risky to build a gun for a single bullet, but the selection of 80grn match bullets are decent and would work if the 90's didn't. Now if that was the case, you would lose that BC advantage, but you would still be able to drive 80grn VLD's or SMK's at crazy velocities.

Just quickly I did the drift comparisons between these and for a 90grn VLD going 3050 it has a drift of 69.18" in a 10mph wind at 1000yards. The 80grn VLD @ 3200 has a drift of 86.26 and the 6mm 105VLD @ 2950 has a drift of 83.60.

The drop over 1000 yards for the 90 is 263", the 80grn is 261" and the 6mm is 296".

So if the rifle could shoot the 90's, it would do very well in the right hands IMO.

Even if you could get 2700fps out of a .223 90grn combo, it would still only have a drift of 84.8. Mind you the drop would be 352" so a tapered mount would be in order :cool:
 
Max,,

I really don't think ### built a 22 Dasher,, so when you see the guy from your club I would check with him again.
 
I am all for doing stuff different, and with the excellent selection of components for a 22BR, it would make a great cartridge!!

There are many excellent choices out there for pushing 224 bullets FAST without the need to wildcate the brass. The 22-250 and the 220 swift are a couple that come to mind.

Honestly, I dont care how much drop or drift a bullet has. The bullet must be ACCURATE!!
I can adjust for drop... thats what the knurly thing is for on top of the scope. As for wind drift, that too is a matter of reading conditions. No matter what cartridge you're using, you need to know HOW MUCH to adjust for a given condition, especially at 1000M. A dialed-in 22BR could be wickedly accurate, but you have to know how much to steer it. SteveB is taking his to the US National F-Class Championships with CyaN1de and me. I'll be shooting 6.5-284, Cy will be shooting a 6BR and Steve a 22BR. SHould be interesting
 
I am about to do some testing to look at the 90gr Bergers in two directions.

F TR - love the idea that you can make a 223 into a 308 eater. Long throat, a case full of powder and go hard. Will not be the first doing this but it is still a fairly new concept. I have already shot these bullets in my tactical 223 and it shot just fine in that Shilen Nothing difficult to tune.

F open - will push them in a 22/250 and see if I can get them to scream 'UNCLE'. Although the 22BR/Dasher are very interesting for performance, run the numbers with the 90gr going 3200fps. no idea if the bullet will actually survive and shoot well but if it did, a very interesting combo.

Maybe a 22/250AI will be in my future :)

Building any rifle for 1 bullet is a risk but with Berger being the supplier, at least you know the bullets will be well made.

I have shot the 7mm 180gr Bergers in a couple of Shilens and they were pussycats to set up.

With quality barrels and proper load technique, I haven't bumped into a situation where a barrel sprays any match bullet. maybe not bughole but always V bull adequate.

The lower recoil will be a nice bonus...
