[QUOTE="AZShooter, post: 1197734, member: 5219"] I agree with ksubuck, you might be into the lands. An easy way to SEE is to polish the jacket with fine steel wool then chamber the round. If it is contacting the rifling you will see evenly spaced rectangular or square marks on the jacket. The creator of this round, [url=http://www.ballisticstudies.com/Knowledgebase/7mm+Practical.html]7mm Practical[/url] states load data of 71-74 grains of h1000 for the 190 gr bullet. No mention of the heavier 195 berger. Perhaps your load of 70 gr of h1000 is just too much for this bullet? Have you tried lower powder charges? It sure sounds like you are way over the top with the powder charges. I too want to hear what you are getting for velocity. [/QUOTE]
