No, I assume these were designed for modest ranges (0 - 250 yards) and meant for deep penetration and expansion.SD is off the charts though. Gotta be a great hunting bullet if you can get them to shoot. I’m guessing not originally intended for long range application
My main hunting load is 175 gr Hornady round nose at roughly 2700 fps. The round nose seems to penetrate straight and expand well. It's also one of the most accurate loads for my rifle. I agree with you that the focus is on extreme distances that border on what I'd consider unethical.the 7x64 should be able to throw those about 2,400-2,500fps. IF your gun will stabilize them. That is like trying to spin a pencil on its point and keep it upright like a top. 7x64 is usually a 1:9 or 1:10 twist. according to Berger's Stability calculator and This data about the bullet, if your gun is 1:10, it will be really on the brink of solid stability at 2,450fps. At 1:9 it should be fine down to a muzzle velocity of 1,500fps or maybe below.
I wish more people made bullets like the older style. I would love to find someone selling hornady 175 grain .284 RNSP bullets to load in my .280 Rem.
best of luck!
I loaded with H4831 SC with an almost max load. I fear that I could push them faster, and they may stabilize for a short distance and then start to tumble. I don't think my rifle has a fast enough twist rate to stabilize reliably, even though the calculator on the berger website stated it would.I believe that they were originally intended to be used in the 7 mm Remington Mag at full hilt. Back in the 80's, one of my friends used them in a Rem 700 with a full case of H870. If I remember right, he got acceptable hunting accuracy (1 1/2"-2" groups at 100), but nothing stellar. When he bought them, he got some Barnes data to go with them, this was pre Barnes reloading manual era.
@Nomore606I stumbled a cross these, and they are in pristine condition. I'm planning on loading these for my 7x64 with H4831SC. Does anyone have any experience with these bullets?View attachment 570754
