I bet this is a fun project for whoever is working on it large frame AR/short action DBM mag length restrictions for OAL, low case capacity for typical bullet weights in that bore, long but slow bullets to stabilize at two different velocity thresholds, most customers probably won’t want a barrel much longer than 20”, that’s a lot of compromises to fit into one package. any supersonic advantage gained from higher SAAMI pressure will be reduced a bit from a smaller case capacity, The shorter shoulder length would help a bit with seating longer bullets at mag length which will help on both the sub and super end of the spectrum. 030 to keep bolts from chambering on a 6.5 creedmoor in an 8.6 chamber meaning even less capacity. 338 Fed/.358 win cases but the creedmoor case already has less capacity and they will probably do something legally well advised like push the shoulder back. I can see some of the argument for using a creedmoor case from being able to run at slightly higher pressures than the. Maybe some companies will make some 338 bullets better suited for this cartridge? The 230 ELD-X seems like the best to me but if I'm missing something I'd love to hear it. I'd love a 12.5" large frame that is as versatile as this cartridge seems.
Very curious how fast the 230's will be pushed with this cartridge. Would love to hear more thoughts / comparisons. Heavy subs for <100 yds and supersonic capability to 200-250 yds.įor comparison, I used the 6.5 Grendel shooting a 130gr Berger at 2400 fps. The 375 Raptor seems much more like the AR10 version of the 300blk. It can obviously shoot heavy subs as well. This comparison only gets better if the 8.6 can shoot the 230's faster. Both these cartridges are within 0.5 mil to 750 yds. The only downside is obviously trajectory (13.4 mils to 1k vs. JBM says the 230 ELD-X stays supersonic to just over 1,000 at 2k elevation with a MV of 2,200 fps. To me, it almost seems like the 6.5G big brother if it can push the 230 ELD-X at a decent speed.
