Running down a rabbit hole, and I wish I had not.
I was building everything up on my reloads based around the Hornady ELD - which is spooky accurate factory ammo.
Then I get to running numbers for my Moscow Match and came out with this....JBM ballistics all factors being equal except the bullet and MV. Using my known velocity numbers for the 123 ELD, and based on my own results, I am pretty sure I can hit the max load MV of 2680 on the Lapuas.
I think LRRPF52, or someone else already ran the numbers like this and was contemplating the switch as well.
200 rounds of ladder loads, 3 different powders 2 days of loading and shooting to find what I need to do with the ELD, and now I have to go through it all again. CRAP!
Less drop, less wind drift, and only 19FT# less energy at 1k. What is not to like?
If this proves to be the case, and my barrel happens to like the 108s, cost of this hobby just went up 15% (more powder, expensive pill...)
