[QUOTE="Mule, post: 129467, member: 6897"] I have a stock grade 308 varmiter which has the typical long throat. I have read this is purposly done by the big gun companies to limit the possiblity of pressure spikes from rounds "jammed against the lands". Does this pressure spike occure anyway even when off the lands or is it proportional to the jump distance? Also, since I am looking for accuracy, what is the recommended (general) jump distance. Thanks Mule [/QUOTE]
