Quick Drop vs Danger Space

[SDHNTR]

When I go hunting, the only quick drop I want is to keep me out of danger space when the morning coffee hits.

I dont want to take this post off topic. Im not sure if this is a tangent or if its a subset of the DS vs QD conversation. So @B_Reynolds_AK if this seems off topic please feel free to shut me down.

Re bdc @solarshooter I may very well be doing things wrong or only in part. But I shoot 2 rifles mainly, a 6.5cm and a .270win. The 6.5 fits into quickdrop well. I basically dont use my calculator except as an occasional double check. Out to the range I routinely practice (generally 550yards and under just based on available place to shoot) the error is always less than .2mil and generally .1 so theres really no relevant correction factor. If I go up 8000’ in da—that is from my local areas at 500-2000’, going up to where we hunt in the rockies at 8 or 9k’ elavation—the amount of error actually is less. So theres is NO correction to make.

My 270 on the other hand does not fit well into quick drop, I have to use a correction factor to make the same hits that I do with the 6.5. Then when I go up in elevation I need an additional correction factor, it ends up being over .6mil off. Im too dumb to effectively manage this mental load, and I commonly make mistakes applying the right correction. I DONT think the correction changes enough in the course of one hunt that it requires much of a change in real life. BUT I havent been able with my level of practice to apply it effectively even within one zone of DA.

Bottom line: quick drop is not the bottleneck on my 6.5. But it may be the bottleneck on my 270. I would not bother with a bdc turret on my 6.5 for all the reasons you outlined. But I think a bdc solution might be a benefit for me on my .270. Id be curious what form or some of the other folks have to say about that, especially given how forgiving of ranging errors some of the flat shooting cartridges can be at more moderate distances.

What bullet and speed out of your 270? I know some folks are getting basically 6.5 PRC performance from a 270. Which I would consider right at the top end if not above the threshold of tolerable recoil for any decent volume of shooting.

BUT Im not talking volume of shooting. Im talking a ballistic solution for any shot. I practice with the 6.5, they are +\- the same gun so my practice easily transfers. Yes, recoil matters and thats a reason why someone might not choose a super-flat cartridge. Yet, the 270, 6.5prc and plenty of other flatter-shooting cartridges still exist, and those folks using them are still left to find a shooting solution—a corrected QD or a BDC turret of some sort are options for those folks. So while I agree that recoil matters, its not relevant for the question of “qd vs ds” or “if qd then why not bdc?”. Substitute a 22cm if you need, I just tossed out the example Im most familiar with.
