I agree with everything you said. And that being said I shot a 6 br with 107's for a good while. It was not a dasher but I could handle the drift with it. My hat is off to Gene that was great!! And fun to watch. But the 223 is just too much different than my other guns. And I can barley shoot them. If I can get 6br performance out of the 22br I will take it and run. Those 1000 bullets may be all the barrel has in it anyway. By the way it was good to meet you in St. Louis. Was telling someone about your experience with four shots in the target today. Surely someone out there has some info. or has it all been tried and give up on.In the past I've played around on paper with the idea of pushing 90s in a 22BR. My recollection is that upper 2900s to low 3000s is about where you might expect to end up at reasonable operating pressures, but it's been a while since I ran the numbers. If that holds up, you're talking about very similar performance to a 6BR with 105 Hybrids, but probably not as good as a Dasher. There are several people here that have run the 90s in a 22BR, hopefully someone will chime in with some firsthand experience.
With regard to .223 Rem/90 VLD performance, certainly there are .308/200+ gr bullet combinations that will outperform the .223. However, that comes at the cost of significantly more recoil, which is one reason the .223 with 90s really shines at 600 yd in relatively benign conditions. It's just extremely easy to shoot one with outstanding precision. Wind drift is wind drift, some cartridges and bullets will give you less, but they also generally come at the cost of greater recoil. Just remember that Gene Novaczek won F-TR at the Sierra Cup shooting 90s in a .223. He had to earn it to be sure, but the combination gave him the tools he needed to get the job done. In general, selecting a bullet with a better BC will buy you more in terms of wind resistance than simply pushing a bullet of given BC a little faster. In other words, increasing velocity doesn't normally gain you as much as moving up to the next higher BC class of bullets, whether in the same or a different caliber. Without a doubt pushing the 90s at ~ 3000 fps would buy you a little better resistance to wind deflection than a .223 pushing them in the mid 2800s. But it's not a HUGE improvement. A Dasher pushing 105s at better than 3000 fps would buy you a little more forgiveness, but should still have the relatively mild recoil of the smaller caliber cartridges. Moving up to 6.5-47 Lapua, 6.5 Creedmore, or even a straight .284 Win would buy a LOT more resistance to wind deflection, but they would no longer have the mild recoil associated with .22s or 6mms.
22 DASHER WILL SERVE YOU BETTER WITH THE 90'SWell said Greg. This barrel is off of my 223 FTR gun I shot in the sierra cup with you. I don't think I will ever make a FTR shooter. Cant stand the wind drift. So Back to the 6 dasher. I'm looking to make a 22br to shoot a local shoot with a hunter class stock. I may be wrong but I'm thinking more speed may keep the bullet on track better at 600. The 223 was great in less wind. I just cant keep up with it at 600. 2' of drift is not for me. Not enough wind flags to keep up with the changes. So yes I'm looking for loads for 600 yds. stuff. Bergers manual is not in the ball park. Was getting that stuff from a 223. By the way I have 1000 sierra 90gr smk's that I'm going to use for this load. And if I need to go to a 22 dasher to get this to work I will. Thanks
I built one several years ago and shot 90's from it. I found that it was extremely sensitive to the winds also and the bullets were the limiting factor. The bullet design isn't as stable as it could be and, in part, the cause of the wind issues. I eventually went away from it and built something else. The 80 grain series of bullets are better bullets for the winds. I did use H4350 in the case and it was extremely accurate. The reason I built it was that, other than the case itself, it used common supplies to my other 223. I used H4350 in it also.
I did the ladder test 32.0 gr h4350 shot a .152 group at 100yds. So I loaded some more a week later it shot about the same. Was going to set up croney and then I saw a fly on the target. We can talk about that fly in pastince. I will take it to a 600 yd varmint match for the next test. It will make one great varmint gun at least.Or he likes them so much that he doesn't want other people to try them.![]()
I'm have a 22br with a 1 in 7- 28 1/2" long barrel throated for 90 grainers. Looking for starter loads. would like to be around 3050 fps. I was thinking vv540 powder or h4350. I have read everything I can find but not much out there. Thanks in advance
