Hornady 75gr ELD Match for AR-15 loads

[dwalker]

Has anyone worked up or are working up loads for these?
I picked up a couple hundred of these to develop a new midrange- 400-600yd- load for my 3-gun AR's. I am going to start wit my standby TAC but may also load some 748, AR-Comp,4064, etc.

I think I am going to start with 24gr of Tac and go up to 24.3 and 24.5 from there. 24.3 is a great load with the existing 75gr BTHP-M.

Report how you do.

On Sniper's Hide, some were saying that because of the length of the 75s, loading to mag length caused them to lose effectiveness and stability. People were saying the 73s were better and could be loaded to mag length without compromising stability. Someone posted good groups out his AR, but he was single loading them.

I use the 75 gr BTHP

I used these in my 16in LMT, I used CCI 41 primers and PMC brass. I used the following powders.

TAC - Best group .80 - average 1.05 - worst 1.25
Varget - Best group .65 - average .85 - worst 1.05
RL15 - Best group 1.00 - - average 1.23 - worst 1.50
BL-C(2) - Best group .85 - average 1.10 - worst 1.33

All off the above were shoot at 100 yards. LMT is by know means precision barrel but it is my most accurate AR. I seated the bullets to the standard length and crimped. Each powder was on the mid to higher end of powder weight but not close to max. PM me if you need more info.

I was wondering about the length, but not really that concerned about it. In my 6x45 I shoot the 90gr bullets just fine. The hope is obiously is can I push them fast enough in the 1-8 to stabilize. According to Hornady the 1-7 is optimal for the 75's and 1-8 optimal for the 73's. All the data i have found for either has the COL at 2.260, but lets be honest, there just is not a lot of data out there for the ELD's as yet. If I do not get good results out of the 75's I will pick up some 73's, no big deal there.

My 75gr BTHP-M loads are .7 or tighter @100yards, off a rest, no rear bag or lead sled etc.. I seat to 2.260 using the RCBS competition seating die, no crimp. I use Wolf primers and 24.3gr of TAC. Generically I use LC brass, although Winchester brass seems to give as good or better results. If I do my job they go one for one on 600+ yard targets, on the clock.

The 75gr ELD is a completely different bullet than the BTHP-M, which is why it may or may not deliver the accuracy I want. Might have to go to the 73gr, should have bought a couple hundred when I bought these.

Pic is 75gr BTHP-M @100yards, the two shots left and right were testing click movement

Case Neck Appearance

Hi - I'm just getting into reloading 75Gr Hornaday ELDs for the first time. When I seat the projo to achieve the correct OAL there is a gap at the top of the case between the outside surface of the projo and the case mouth. Obviously this is because the projo has such a long ogive. Am I to crimp enough to close the gap so the case mouth is tight around the projo? Or not crimp at all? Or something in between?

Thanks, Tim

Today I was able to visit a range for a little practice/r&d session.I used the 73gr eld with 24.8gr of Varget,velocity unknown,but would expect to see something near 2800fps based on testing recently with the 75gr bthp and 80gr eld,both had a avg nearly identical of 2,780fps using the same 24.8 charge of Varget.

Do not crimp and do not expect to load these bullets mag length as they are to long.

Jump?

Got it - single load rounds. How much jump do you recommend?

Thanks!

Thanks!

I go with .020 jump.The 73s I shot yesterday ,15rds had .020 jump,50rds mag length.

[Intiminator]

okay - new question - assume you have an 308 cal AR10. Do you crimp your ammo?

[jtake]

I do not crimp any of my loads for large or small frame ARs. I have not had any issue with set-back or stuck bullets after ejecting a live round for over 10k rounds I have loaded.

[dwalker]

I could not get the 75's to seat at 2.260, so they are single load fodder. The 73's seem to be OK at 2.260.

No!

Thanks all for your support and guidance.

I loaded 75gr ELD, OAL is 2.500-inch with 0.015 jump. Shooting these and some variations tomorrow, will share results FYI.
