Yessir. For the lots of bullets I’m using, and in my barrels, an average G7 value of 0.351 has worked very well. BC obviously depends on multiple variables, including the engraving/deformation caused by individual barrels, so drag profiles vary.
In terms of the "best bullet here," I can agree to disagree, and I'll afford you the same luxury of continuing to buy and shoot your bullet of choice. Leaves more 147s for me. :)
Yeah, that looks like a very unstable design. I make brackets out of electrical conduit (they each accept two legs and a crossbar) but use rebar for the legs and crossbar themselves.
Thanks. I'll disagree that the 147 provides no advantage over the 140 ELD-M or 140 Hybrid within 600 yards. Winds are seldom constant, and any advantage to decrease the variability in wind drift is meaningful, at least to me.
Your point about 2000 fps minimum impact speed threshold is not...
One other benefit to the slow, heavy bullets, such as the 147 ELD-M in the 6.5 CM, is the consistent terminal performance. Most C&C bullets tend to behave pretty predictably when impacting at <2700 fps, and the high BC of the 147 means that it loses speed at a slower rate, so the impact speed is...
At what distance and in what environmental conditions? The relative wind drift between those three bullets changes with distance, with the 147 gaining advantage as distance increases.
I don't have a pic handy right at the moment, but I use Grade 8 bolts and washers on the face of the target, with a ~3" wide strip of mud flap on the back of the target with Grade 8 nuts and washers back there. I also add some washers between the target and the strap to give the target a bit of...
