[QUOTE="Echo Charlie, post: 1618027, member: 109774"] Would you please give me your opinion about this 6.5CM load? Any comments are appreciated. Lapua SR primer cases. CCI BR4. Vihtavuori N550 powder 147grain ELD match 24" barrel COL: 2.880" (Maximum for magazine). Lands @ 2.913" (.033" Jump). [B]1st test done @ 100 meter.[/B] Before this test fired 10 shots with N150/140ELD_M to harm and foul the barrel. New cases (0 firing). Oheler 35P didnt read velocity of the 38 grain charge [ATTACH=full]130831[/ATTACH] Photo of the case loaded with 41.5 grain. Cratered primer and also visible a light round ejector hole mark around the last "A" of LAPUA lettering. This case measured a slightly larger OD near the base than the other ones. Not noticed signs on the other cases and no bolt lift increased force. [ATTACH=full]130836[/ATTACH] [ATTACH=full]130832[/ATTACH] [ATTACH=full]130834[/ATTACH] [ATTACH=full]130837[/ATTACH] [/QUOTE]
