Lazzeroni used to offer factory ammo loaded with 130 grain bullets, I think they were Barnes. I had some questions myself so I e-mailed Lazzeroni and they gave me some helpful advice.I started out with a conservative load of Reloader 25 (101 grains)with 125 grain Sierras just for fun and slowly worked up to a load that was a bit too hot (111 grains, 3953 fps). Of course I have backed it down, but the light Sierras never shot well, so I tried 124 g Nosler bullets.They shoot great (well, off the bench, anyway), but I never intended to hunt deer with the gun when I bought it.(I use a Marlin 30-30 for that, just about right for TN woods. I just wanted a powerhousefor the fun of it, kinda like my Ruger 454.)Anyway,there is something fascinatingto me abouthigh velocity guns and I was just thinking of trying it in the woods this year...
