Stuck on Quick Drop

[JDMBEND]

By optimal lethality, I was mostly referring to bullet type and weight. Certainly not referring to barrel length as I own a 6cm with a 16.5” barrel.

Example: A rifle that is hammer with Y barrel length and X load. Are you going to adjust barrel length/Load to get quick drop and forgo accuracy?

I get the idea but I’ve never had a barrel shoot better at 22” than 18”

It’s not really an issue.

Reading this thread I am getting a very basic understanding of quick drop. What I am trying to wrap my head around is you all are essentially building your rifle and loads to utilize quick drop?

Yes.

So you are potentially compromising optimal lethality for quick drop?

No. You might lose a little lethal range out past 600 yards where most of us have no business shooting at animals unless they are huge.

There are some guys that are intentionally down-loading loads to match up with QD. I personally don’t like this method, but to each their own.

Y'all are still fixating on neutering. It works both ways.

Here are 3 examples from my own life:

1) 18" 6.5mm barrel. It has to be 6.5 PRC instead of a standard case to make quick drop with 147 ELD and 156 EOL. Just like that, I'm a magnum guy.

2) Goal was to send 200gr bullets and make quick drop with a 22" unthreaded factory 308 barrel already in hand. Testing shows the 308 chamber might need a 26" barrel (probably longer that that) to make quick drop with a heavy bullet. I bump it up to Sig Fury brass to make it, since regular 308 loads won't make it. Research shows it probably needs to be a little longer than 20" to make speed. I threaded the barrel without cutting it and it worked. Just like that, I have one long barrel rifle.

3) It would be nice to have a 223 that makes quick drop with heavy hunting bullets. I'm at sea level. The barrel would have to be 22". No thanks. I have tons of 6.5 creed once fired brass. 22 Creed it is.

Example: A rifle that is hammer with Y barrel length and X load. Are you going to adjust barrel length/Load to get quick drop and forgo accuracy?

This is getting into mythology about "loads and nodes" and too theoretical for something that won't play out in the real world.

QD is pointless if you have a rangefinder that does ballistic calculations.

...until something goes wrong.

If your range finder breaks, qd is out the window too

My thoughts go like this:
Plan A is obviously use my own ballistic rangefinder.

If that goes down, resort to plan B. I’ll have a dumb rangefinder back at the truck or on my hunting partner.

QD lets me make accurate shots off other people’s or my own back up equipment beyond MPBR. Without it I’m flying blind, and really limiting myself to whatever the MPBR of the gun is (also something I practice).

It may even keep me in the field, rather then needing to bail back to the truck so long as my buddy has a working rangefinder.

It’s certainly a useful tool. But I’m not selling my range finding binos any time soon. And I’ll certainly hunt with a non QD rifle when it’s the right tool for the job.

 

[HuntHarder]

That is a scenario where it could be useful. My backup plan is still a laminated dope card in my pack and also one on taped to my stock.

QD prints 200/300/400(+) in your brain in a way that does not require math. It's liberating.

Seems I have read on here velocity's numbers from 2500-2850 working with Qd.
If you get past 5-600 yards does that number need to be on the higher end?
Just curious about the velocity difference and how that plays out.
All my rifles (223/6.5cm) are 16 inch so i probably handicap myself some with factory loads.

A few minutes with a ballistic calculator will answer all of that for you, for your guns- or any other.
