[QUOTE="Capt RB, post: 1507049, member: 85987"] ELR starts beyond 1000yds. Time of flight doesn't matter on steel/paper. Live animals can and will move with the extended time of flight involved. The energy standards of #1000 for whitetail and 1500 for elk are well entrenched. Can you kill either with less of course. Inside of 1000 yds time of flight is 1 sec or less for alot of cartridges. My creedmore load hits 1000#between 950 and 1000yds. This is a 147@2830 sea level standards. Time of flight is 1.26-1.35 between 950/1000. I'd shoot a coyote in a heart beat here. A deer would have to be perfect conditions for me to consider a shot. If I stepped up to the 7mag I would feel better about it if my 7 shoots as well as the 6.5 does. Have not sorted it out yet. If I can get to the upper end of the velocity expected I will have much more energy and a 1/10th second faster tof to 1000yds. Step up to stw or nosler and you get more energy and a few 1/100's quicker tof. Plus the option of running a higher bc/heavier bullet without a huge tof penalty. It is these aspects of elr that really need to be addressed A 1.71 second tof to 1300yds for a hot 180/7mm load would need a dead still animal. Only a bedded one provides that. Being able to 100% make that shot weeds out alot of folks. Using a big 30 with a 230smk@ .8 bc at 3100fps can deliver 500# more energy @1400 than that hot 180gn load does at the same 1400yds. Now you would need the bullet to transfer it to the animal. That would mean using a lower BC bullet like the 225eldm and your down to #350-400# more than a fast 180. The 195/7mm 3100fps would be 250# less energy and a solid 1/10+ longer tof. This all expecting you to be able to 100% call the conditions and be able to shoot better than 1/2 moa cold bore. I purposely used 1400yds because of the elr standards used in the event early this year. 2 shooters did this @ 1500 and 1 other did it at 1760 and 2011yds. 1 was using a 7mm stw. The other 2 were using big 375's with bullets with much higher bc's on a static target larger than the kill zone of a deer and pretty close to that of an elk. You can look up on youtube some of the videos of that event. I recognized most of the shooters that didn't do that.
