A lot of you are quoting a COL this high; are you shooting in an AR-15? I made my first Grendel reloads, and used the exact COL specified at the AA site for 123gr Lapua Scenars, which is 2.265. At that length, the bolt would not even close all the way. (Not only that, they would BARELY fit in a standard USGI AR-15 magazine.)
I measured about 10 factory loaded rounds (by AA), with 123gr bullets, and they were from 2.241 to 2.249, with an average of 2.246. Those work great in my rifle. However, I can't find any official published load data for those Lapua bullets and a shorter COL like that.
For those you actually shooting an AR-15 platform, what COL do you use for the Grendel? Do you have problems with the longer bullets? I am assuming it's not too safe to just seat my loads deeper by .015 with the same powder charge.
Thanks! </div></div>
I follow all of Alexander Arms load data.
Yes, I shoot from a AR-platform and do not have any problems with mags when I seat out to 2.260". Thats what I seat 90% of ALL my bullets out to. Also 2.265" will even fit in my mags and run fine.
I dont have any problems with the longer bullets either.
I dont understand why you are having that problem. It sounds like there is something wrong somewhere.
I am using specific AA or C-products 6.5 grendel magazines NOT USGI AR-15 (.223) Magazines. The 2 types of mags are different.
