SIRJ,
IMHO, you're idea has sound merit. If you can find them, the Hornady 154 gr. RN (#2835) and the 175gr. RN (#2855) Interlock's are fine bullets. I have used both of these out of my 7mm Rem. Mags, and they work very well on deer out to 200yds. IF YOU SLOW THEM DOWN ! 2550fps. or so for the 154 grainer and about 2450fps. or so for the 175gr.
They do not have the higher B.C. of their like weighted spire points, but they have adequate sectional density for their bore size that carries very good momentum when they get to the target. Yes, they will have more of a rainbow trajectory than the spire points, but you can factor for that with just about any good scope, and yes, I said out to 200 yds. The 4th edition (1991) Hornady Reloading Manual has recipes for both bullets. I hope you can find them. Good Luck.........
