I believe PVA uses a 0.145” freebore for 6.5x47L, which is perfect for Hybrids but ~0.050” short for ELDMs.
I had the opposite issue last year, my x47 was made with too long of a freebore, so I pretty much had to switch from the Hybrid to ELDM. At PRS style comps I didn’t notice any difference downrange, though I did feel dirty not shooting my precious Hybrids lol
If you’re using Varget, you will likely have plenty of case capacity left to stuff an ELDM down the neck a bit. If the cost savings is worth it to you there’s little harm in picking up a box of 100 and trying them out to see how they shoot. It’s a x47 so it’s very likely it’ll shoot lights out with any bullet you throw in there.
Or wait til you have 1000 rounds down the barrel and switch to the ELDMs, as the throat erosion should have you in a good spot.
