I just got my very first Savage Tactical 110 6.5 Creedmoor. When I removed it from the box and looked at all of the components that came with it, something stuck out about the PMAG 10. It said on it '7.62 X 51'. I was thinking my rifle only took 6.5 Creedmoor ammo. Is 7.62 X 51 an alternative ammo for this rifle? Thx!
What does it say on your barrel?Originally Posted by Rlharwood
Sounds like you got the wrong mag. 7.62 x 51 (aka .308) is not even close to 6.5 Creedmoor.
The barrel says '6.5 Creedmoor'. So it looks like I will need to find some establishment local that could take a last look st it and make some kind of trade.
The parent case to the 6.5CM is the 308Win/7.62x51. There is not a dedicated 6.5CM magazine. Pmag does not stamp every caliber that will work on the magazines, only the parent case.
That is great news! I had a feeling this is a very good forum! And it is! I learned something today! Thx!!
It's the right mag. The ".308" PMAG will hold .308/7.62 X 51, .243, 6.5 Creed, and a lot of others with the same width case.
Parent case for the 6.5 Creedmoor is .30 TC.
This is exactly right. The 30 TC was the parent to the 6.5 Creedmoor. The 30 TC is just a 308 that has been shortened a bit though. As far as the magazine is concerned they are all the same, because the body diameter is the same of the cartridge.
I believe that the reason Hornady chose the .30TC (1.910 case length) for the parent case of the the 6.5mm CM was that they had plans to use it in an AR 10 frame.
The 6.5mm bullets are much longer than the .30 cal bullets and would have to be seated back further into necked down .308 case at 2.005 case length and SAAMI recommended 2.800 O.A.L. for a .308 - (7.63x51) to fit in an AR-10 mag.
The 30 TC case would give about 0.095 more space for the longer .264 bullet to be seated out of the magazine when loaded to the SAAMI recommmended2.810 O.A.L. for the 6.5mm CM.
6.5 cm uses same magazine as 308. 6.5cm is based on 308 TC, 308 TC based on 308 win. Virtually Identical case dimensions. At least in AR10 world you use 7.62x51 magazine for 6.5 cm
