[QUOTE="BryanLitz, post: 910503, member: 7848"] [b]Re: 300 grain Berger Disappointment - What am I doing wrong?[/b] montana_native, Please verify the twist rate of your barrel. What you're describing is consistent with a twist rate slower than 1:10". A 1:11" would shoot SMK's well but Berger Hybrids not so well since the Berger's are longer they need a true 1:10". You can check barrel twist using a cleaning rod with a tight fitting patch. Measure how far the cleaning rod travels to complete 1 full turn. Repeat the measurement several times and take an average. Another thought, has the rifle shot SMK's well since you started trying with the Bergers? Maybe something happened about the time you switched bullets? But if the rifle shoots SMK's well, then Bergers poorly at the same time, that would indicate the difference really is related to the bullet. Take care, -Bryan [/QUOTE]
