75 Hornady ELD and AR15s are a no go.

[Member 34319]

It was worth trying.

Was going to see how these do through the AR. Well, that's likely not going to happen. Bullets are too freaking long to fit the magazine. I kept pushing the pull down, test mag, push a little further, test mag. Nope. Ogive is starting to go under the case mouth.

Sometimes stuff just don't want to work together! Irony is I should have known as Hornady lists the COAL at 2.390. Something I should have noticed before starting! Hint hint, read your reloading books!

Anyways, I'll pull the one I sat and they will end up in the classifieds if I don't find a use for them (cough cough looking at Savage rifles online in 223)

What is the shortest COAL you can get to before hitting ogive? ASC Stainless mags supposedly allow for 2.3"

I think a bolt gun would be the ticket.

My Savage 223 has a 1:9 twist. I wonder if faster twist rates are hard to find in bolt guns. If these were being used at bench for target shooting I would hand feed them or modify a single mag.

My savage is also a 1:9 twist and shoots lights out with 77gr SMKs, and Nosler CCs

3 shots @ 100yds with 77gr Nosler CCs

Looking at some of the 110s. The predator model.

I'll go take a look see. I think it was LC brass but I'll check.

Mine were dicks and cabelas specials. Not the Axis, but the next step up.

Interesting. i wonder what the bullet length difference is between the 75gr Hornday ELD and the 77gr Sierras they use for Mk 262 mod 0/1. never saw an M4/SPR/DMR rifle that wouldnt eat them from the mag.

FOR REFERENCE ONLY DEEMED SAFE IN MY RIFLE!!

LC 08' brass
CCI 400
77gr Nosler CC
IMR8208XBR (22.4gr)
2.263" COAL
2.892" Base to ogive (Sinclair comparator)
.016" jump to the lands
.003" neck tension

Note:
This load gave a 3-shot group .108" in my older .223 bolt action savage from Dicks.

The same load produced the group above in another newer savage .223 bolt action I got on sale several years later as a Cabelas special. It was cool to see it worked so well in two different rifles made several years apart!

I had a feeling your specs would include that wonderful pixie dust 8208...

People load those for single shots.

 

[Towhead]

Amax are too long also.

Mk 262 is loaded to 2.245.

My 8208 load is 23.6 with 75 Prvi
and 77 Nosler CC.

Some bolts, like the RAR take an AR mag now - but the cartridge could be loaded singly.

 

[eb in oregon]

The 75 grain ELD (and those heavier) was designed to be single loaded for long range competition, it was never intended to be magazine fed. And those I know that shoot it competition all acknowledge that fact.

 

[ma96782]

YUP. I can remember back in the day. When I was into service rifle shooting and some of the bullet manufacturers warned that certain bullets (longer/heavier) would have to be single-loaded (directly into the chamber).

But....since it would probably only be for the 600 yd (and beyond) slow fire match......well, it was acceptable for some.

BTW, the Sierra 69 grn BTHP will work out of a magazine.
