[QUOTE="Justice1327, post: 2113821, member: 117337"] I have experimented with small primer and large primer Lapua 6.5 Creedmoor brass. Each of my handloads loads get me 2900 to 3000 ft./s which is definitely on the upper end. I saw very little velocity variation between the two. however, I did see lower ES/SD using the small primers. I even drilled out the small primer brass to the same size/hole as would be in a large primer case. This actually netted me slightly higher velocity and still maintain the lower ES/SD. If small primers are thinner I didn’t notice it. [/QUOTE]
