Hello there from the "Newbie Canuck!"

I have an BRNO 602 in 8x68. I have a Leupold VXIII 3.5-10x40 on it. It's a fantastic calibre. Just this morning I was reading an article by Karl Stumpfe about it. The articles are actually from this forum from 2010. The article is a bit blurry unfortunately but here is the link: nitroexpress.info/ezine/Articles/KarlStumpfe/germanysgreateight.pdf

I like the 200gr Nosler partition, or Speer 175 or 200gr Spitzer depending on game being hunted. 8x68 is on par with the 8mm Rem Mag, or 338 Win Mag just more pleasurable to shoot.

200gr bullet is going to give you around 2900fps at the muzzle. ME would be about 3700ftlbs. If you hold 3" high at 100m your drop at 400m would be about 17". 400m velocity would be around 2100fps & ME around 1440ftlbs.

175gr Sierra is going to be around 3025fps at the muzzle. ME is 3550ftlbs. 400m stats MV 2114fps. ME 1740ftlbs. Drop about 15" if holding 3" high at 100m
If you're 2.5" high at 100m then it drops an additional 2.5" for both loads at 400m.
Data is from RCBS Load V3 program using 25.5" barrel.

I'm sure the Speer Hot-Cor, Swift A Frame, North Fork, or Lapua 180gr Naturalis would be decent choices as well. Barnes 200gr TSXbt would be interesting to play around with also.

I used to use the Hornady 150gr Sppt to hunt groundhogs with devastating effect.

If you need anymore info I'll see what I can do.
