GeoJRP Custom bullets: 25-gr .224 cal bullets?
Has anyone used these before? I believe he also produces a 40-50 gr .243 cal and 80-gr .308 cal bullet as well. They have been mentioned a few times in Rifle Shooter, most recently in the July/Aug 2001 issue. They were running 25-gr HP's from a .22 Hornet at 4000 fps with 0.3-0.5" groups!
I was wondering about the BC of these rounds, though. They are lightweight, but the pictures show them as being longer and more streamlined than the 35 gr V-Max or 45 gr SP's. They also mentioned that the OAL of the JRP load was too long to function in a standard Hornet magazine. Is it possible for these to have a higher BC despite the light weight? After all, weight isn't supposed to be important in BC, just sectional density and external shape. Thanks.
PS: anyone know the price per 100? I have the address, and plan on buying some to find out for myself.

<eldeguello>I have used them, using the info from the Rifleshooter mag. you mention. My results were nowhere as good as the mag. author got. I could obtain neither the accuracy nor the velocity he got. I went back to "regular" bullets in my Hornet.

<eldeguello>Sorry, forget to address the BC part of your question. Weight IS IMPORTANT in BC- because, weight DETERMINES sectional density. SD=weight(grains)/7000/bullet diameter squared.
