Anyone tried it yet? What do you think--and how does it compare to alternatives? I'd like to try Lapua's but it's unobtanium.
Looks like a fairly typical RN profile to me, the only thing that jumps out to me as that the bearing surface ribs are not as pronounced as they are on other 22lr bullets. I'll do some measurements and comparisons.I have seen both companies claim that they "optimized the ballistic coefficient [or drag]" of the bullet.
Seems like they just tried to increase weight and give them a flat point.
It's counterintuitive--we tend to think of 22 lr bullets as arcing little things which get "pushed around" by even the slightest puff of wind (which is true)--but the basic 22lr round nose design is exceptionally good in low rate of velocity decay.A low velocity 50 yard round might not carry up to longer range.
I don't know what is terrible about it--other than it seems to be very hard to get performance optimized in just one ammo type for all distances. The subsonic still seems to reign supreme in the 50 yd range it seems to me. As for the barrel length, I just put a 24" CZ barrel set on my other 457 and it seems to do just as well as my jaguar so far, but I haven't been able to shoot it at 200 yards or more due to heavy construction activity in the quarry I normally shoot at. Major bummer as I really need to do some testing of more than one rifle out to 300 yards.While shooting groups, I noticed that terrible trend that we have been talking about for some time.
Ammo that leaves that barrel 'just barely' super-sonic tends to group better than ammo that is well into super territory, or ammo that is totally subsonic.
Totally unreasonable conclusion reached: I need a CZ 457 Jaguar with its 28" barrel, for further testing.
Mine came in and can't wait to try it out--the configuration numbers look good to me, the velocity is very close to what I get with R100 which has done very well out of my jaguar at 200 to 300 yards--but the Norma is using a 43 gr bullet.
Beautiful day here today on the coast of Maine--except that it's blowing around 20+ mph.
Must be a misprint--it says right on the box what the velocity is. 1300 fps or more--especially with a heavier bullet--is a very fast load. I ordered mine direct from Norma.
RWS R 50 and R100 shoot great out of my CZ jaguar; R100 in particular I've had very good results all the way out to 300 yards provided the air is dead-calm. Like the Norma supa dupah stuff, I wonder if the "extra long range" means it will hold its own when the others finally start dispersing worse.
