This is a small sample size, but our sniper element uses the Black Hills ELD-M 168gr for everything up to and including light glass. Past that, it’s Fed 168gr Bonded Tip (LE308TT2). The zero change between the two is minimal. The ELD-M isn’t quite as accurate as the match kings in our rifles, but in gel and through light glass, it’s performs much better. Black hills will send you the bare gel info on request. The matchking almost always sheds its jacket through glass, and you have two impacts on paper. The ELD-M in our testing did this much less, even though it isn’t a bonded core. It’s not perfect, but it’s better.
The FBI hasn’t done the ELD-M yet, but has done the similar AMAX (slightly different tip, very similar terminal performance. BTW - the ELD-M isn’t like swapping to a 6.5 creed at the ranges we shoot (vast majority under 100, but we shoot regularly out to 500 since we have the range that goes that far). BH is a little less expensive than the Hornady with the same bullet last I checked (last year at the beginning of the fiscal year).
