Are you running a factory DT magazine for the 6.5 PRC and WSSM? Factory non modified mags can have issues feeding those short fat cartridges.I have noticed this problem with my 223 WSSM and 6.5 PRC barrels, never had this happen with my 300 WM or 338 LM barrels. I believe most of the problem is the front or neck of the shorter cases get tipped farther to the side when being pulled out through the barrel extension than the longer cases. This allows the ejector plunger spring to extend farther and lose the ability to "flip" the case hard enough to get it out of the rifle properly. I really, really love my SRS! I really like the two short case rounds I have barrels for too, but the DT doesn't run them near as well as the longer case rounds. Magazines are fussy too with these fat short rounds that are a long way from the chamber when leaving the Magazine lips.
Do you have any suggestions or ideas that you know of to make these run better? Available magazines? The 223 WSSM is not very practical in the DT although it is a fun round to shoot, but the 6.5 PRC is awfully nice when it runs semi reliably. I want to get it to run them better. What is the shortest round that you know of working well in the SRS? Who is making the SRS run these reliably?
The DT Magazines work wonderfully with the 338 LM's loaded long with 300 grain Bergers. I love the DT's long 4" cartridge length capability, I load mine at 3.9375" COAL and they run fine.
Any thoughts or suggestions are appreciated!
We have been selling modified mags to our customers with the 6.5 PRC and some of the WSM calibers. Desert tech is now starting to manufacture mags specifically for the 6.5 PRC.
As Second Of Angle recommended, running that bolt hard, especially on ejection is your friend.
