I have accumulated parts for my next varmint build and have never used a HS Precision DBM. I will be building off a Kodiak repeater with built in 20moa pic rail from Kelblys and using his varmint stock also. The stock is completely inletted except for the bottom metal. I would like to use the HS DBM as the magazines will fit flush. Are they a quality DBM and do they feed well or do they have problems and I should look into another DBM to use. I will be building a 6 creedmoor and not sure if you would use the 308 or 22-250 magazines for it.
