Just joined the forum and hoping for some answers. I bought my new Tikka Superlite in 6.5 Creedmoor on Monday, and today I finally got to shoot it. Worst day ever shooting a rifle. I tried out three different types of factory ammo (Hornady ELD Match, Norma HPBT Match, and Federal Premium with Nosler Accubond). Had problems with all three. Groups looked pretty good until I came across a round of Norma that wasn't hollow point. It looked like lead was filled all the way to the tip. I should have thrown it out because my groups started getting bigger after firing that round. One grouping later, I shot a round of the Hornady and I could barely eject the casing. Turns out that the primer blasted out of its pocket and welded itself to the bolt (not literally). It took about 40 minutes to remove the carbon scoring from the bolt after I got home. Frustrated with Hornady and Norma, I switched to Federal which would not even load into the chamber. The box says 6.5 Creedmoor, but the casings definitely have different dimensions than the other two. I was really looking forward to seeing the performance of Nosler's Accubond because I have heard so many good things about it and was hoping to use it for hunting whitetail this year. Sorry for the long post, but I needed to vent. I never had any of these issues (even with cheap ammo) with my .223. Are these manufacturer defects normal? Do you think it has something to do with the Creedmoor being fairly new to the market? I love the rifle, but maybe it's cursed.
