Honestly thinking I might need a custom reamer for .210-.220 as I want to jump it .050

I would personally seat it a bit deeper to avoid a custom reamer. You’ll never fill the case before reaching pressure and could mitigate potential feeding issues.

Heard on case fill, thanks for the thought

What are your concerns with feeding issues? Works in my MDT poly mag with my KS Arms action.

Total hypothetical, but could limit your options to extended length mags.

I wanted “optimal ” seating in my build but after realizing how much empty space is in the case I seated my dummy rounds a bit deeper but not much.

I guess I’m just wondering what you expect to gain from seating the bullet at the absolute edge of optimal that warrants a custom reamer for a specific bullet? It might not like 88’s or whatever and you have to load 80’s, etc.

Optimum seating depth for the 88's to avoid the donut on the case neck

I'm gonna run 80.5 bergers or 80 eldm they can be cranked to 3400-3480 pretty easily I'm not sure the extra bc from the 88 is worth it exp since if you lean on them a little to hard in excess of 3300 they tend to come apart. We've been testing these quite a bit in northern bc and the 80 grain is the sweet spot. The 88 eldm out of a 223 ai or 22 arc or similar at about 2900-3000 in a 1-7 twist is the sweet spot fir that bullet.

May want to check the 80 ELDX for the terminal performance, a lot of good feedback from @Formidilosus on it acting like the 77 TMK

Iv seen the eldx there not to bad some rifles like them some don't I tend to prefer the eldm for hunting even in 300 win mag I run 208 eldm.....6.5 prc 147 eldm or 140 berger vld.... 300 prc 245 eol or 208 eldm some times 212 eldx ... 223 I ran alot of 75 eldm , 243 ai was alot of 108 eldm.

I've shot a lot of the ELDM as well, the 22cal 80 ELDX is proving to be a better terminal performer though was my only point

Oh ok np.... I mean it be worth a try i havnt messed with them much yet.

Avoiding the donut could be an issue if it hates the 88s and your stuck with .1 to .2 jump with other projectiles.

They are longer than the 80 eld ms by a bit.

The 80 ELDX are?

 

[Stocky]

Yes sorry the 80 ELD X is longer than the 80 ELD M. Will try grab some pics and pics. At Sea level I can shoot 80 ELD Ms but 80 ELD X are unstable and tumbling.

 

[SouthPaw]

The 80 ELDX are?

Yes. 80eldm is 1.152 and 80eldx is 1.192.

 

[justin davis]

Yes. 80eldm is 1.152 and 80eldx is 1.192.

Interesting

Wild. Thanks for enlightening, 1.243 on the 88 ELDM. I’ll try and throat it so I can still pop the 80 ELDx’s then

 

[B_Reynolds_AK]

In light of the longer OAL of the 80 eld-x vs the eld-m, despite having the same BC, has anyone seen any point of impact differences between the two? Have you had to adjust your DOPE when going from one to the other?

 

[coleman]

I bought a saami reamer and sent a dummy round with the 88 eldm to the gunsmith. He used a throating reamer, so I was seated optimal with the 88’s. I don’t know the cbto of the dummy round off the top of my head, but I gave myself some room to seat the 88’s with decent jump and still be above the shoulder/neck. I’d like to try the 80 eldx to see how much jump they have with the longer throat.

How much consideration are you giving to the BC between the 77TMKs vs the 80ELDMs? Running them through AB the 77s are a 4mph gun for my load (1.5Mil in a 90* 10mph @ 600M and 59% WEZ on a deer) vs the 80s being a 5 almost 6mph gun (1Mil in a 90* 10mph @600M and 87% WEZ on a deer).

I want to shoot the 77s so my 223 and 22CM are shooting the same thing, but the wind advantage / hit probability of the 80s seems too big of an advantage? Does that make sense? And if it does why the cult following for the 77? Seems that hitting what you're aiming at trumps whatever incremental terminal performance might be gained.

I think your #s are off. My 22CM w 77s is a 7mph gun out to 700 yards
