Hi all I'm new to this site and have a few Savage wildcats (223 AI, 6mm TCU and 6BR). My 223AI is a Savage model 11 with a factory barrel. I had a good load working with 26.6 gr of 748 in federal brass with CCI primer and 60 gr Nosler Ballistic tips when it was just a 223. I had it reamed out and I shot the rest of that load I had worked up while fire forming and they shot well, 3 shots touching at 300 yards. After fire forming I can't get anything to shoot accurate ( less than 1" 3 shot group) at 100 yards. I have tried many different loads of 748 with the 60gr Noslers and then switched to H335, H322 and messed with seating depths and then I moved to 52 Sierra Matchkings and still couldn't get it to shoot. I checked the action screws and gave it a good cleaning with wipe out and no difference. I'm at a lose and frustrated. I have noticed that I'm showing signs of pressure at book max loads for a 223. Any suggestions?
