1. Some people say yes, some say no. I have never had a feed problem. Both my Garands are 7.62. I generally use new or good condition en-blocs.1. Is the spacer block required for reliable feeding.
2. I have heard that the legs on en bloc clips need to separated a bit because of taper of .308 vs 30-06 rounds. Myth or not?
My rebarrel to .308 is due home this week.
That ejection into the head is no joke. 42 gr of Varget and a 175 and my forehead looks like I went a round with Mike Tyson ( alight exaggeration)I have had no problems without a spacer. Always have used FMJ or HPBT bullets - with cartridge OAL ~2.83 inch.
Have never needed to do any bending or alteration to enbloc. I slide the last cartridge into the enbloc by pushing it rearward into the clip - NOT by trying snap it lengthwise alongside the others.
Only functional change has been to slightly shorten the ejector spring to prevent cases thrown backwards into my head.
Both cases have the same head diameter of 0.473 inch.2. I have heard that the legs on en bloc clips need to separated a bit because of taper of .308 vs 30-06 rounds. Myth or not?
IIRC there are clips that dont play well with the smaller/thinner extractor groove. Same problem with 30-06 especially later prouction HXP M2 with "original" GI clips .Somewhere I have a pictorial of what clip fits what ammo base. If I can find it I'll post it.
My match rifle that I had Shuff build my M1D with is 7.62 & I only use JMO clips for it.
There is a particular combo of clip type, cartridge rim style & mfg for this.
