[QUOTE="vitaminado, post: 1779730, member: 90319"] Hello I'm reloading a 6.5 creedmoor with reloader 17 and berger vld hunting 140gr. I've been doing the seat depth test. I have found the best groups at 0.050 "and 0.130" from the lands. At 0.050 I was able to easily reach 2800fps without any signs , but at 0.130 ", I have seen signs of pressure and have only reached 2680 fps. I took 0.130 "because it gives me a better brass fill, but I don't get good speed. I have read this in the forum: My opinion and observation is that when the VLD's are seated deeper, they tend to slow down due to the absence of the pressure spike that occurs when the bullets starts out touching the rifling. What can you tell me about this? Thank you very much and greetings [IMG]https://ssl.gstatic.com/ui/v1/icons/mail/images/cleardot.gif[/IMG] [/QUOTE]
