Fast Double reloads

Well I tried out the fast double reload this weekend.No Video's yet as I'm not ready, but results are promising. I shot my O/U CZ 589 double in 458 Lott at bowling pins at 25 yrds. I used a sound activated Pact Timer and it took exactly 10.5 seconds for four shots with four hits. 1st two shots were in 3 seconds as were the last two. I learned that Loading the lower chamber in an O/U is slower than the upper one. I think I will be 1-2 seconds faster with a SXS and/or with more practice. I need to compare this speed with four aimed shots from my M70 in 450 Ackley. So far so good!-Rob

Robgunbuilder:

Thanks for the information. I will be looking forward to your results for the bolt rifle...

One thing people don't usually bring into the argument about which is faster, a bolt or a double, is the fifth or sixth shot...

You should be able to get off 4 aimed shots in 6-8 seconds with a SXS. That's pretty good for a bolt also.

Great stuff Rob! Many thanks for taking the time to do this for us curious folk!

For comparison's sake only, here are the numbers from the video I shot of Dave E. taking 4 aimed (and accurate) shots with his 470 Mbogo. (watch video here if you haven't watched it already)

Elapsed time from first shot to second shot: 2.09 seconds
Elapsed time from first shot to third shot: 4.10 seconds
Elapsed time from first shot to fourth shot: 6.62 seconds

Note that Dave did this absolutely cold (I was the witness running the camera), and slightly fumbled the bolt between shot 3 and 4, which probably added a half second or so to his time.

These were also 500gr loads at 2500 fps (ie. not reduced loads).

It's interesting to note that Dave's time on the first two shots (ie. while the advantage is still tipped in favor of doubles) are in the ballpark with aimed shots from a double!

It'll be very interesting to compare the O/U with the S/S, and to have a relative comparison with you shooting your bolt gun.

Thanks again Rob. I sure do appreciate your effort. Nice to see people actually get off the computer and try some things!

As someone said, talk is cheap and actions speak louder than words.

Cheers,

Also for comparison's sake, here are the numbers from me taking 3 aimed shots from my 470 Mbogo at a pie plate at 25 yards. This is actually my VERY FIRST attempt ever at shooting a true big bore in rapid-fire succession. I was actually a hair faster than Dave, but was not quite as accurate. I hit the pie plate each time, but did not get direct center hits like Dave did on the water buckets.

The video of me can be seen here.

My times were as follows:

Elapsed time from first shot to second shot: 1.81 seconds
Elapsed time from first shot to third shot: 3.99 seconds

Since it was my first attempt at this, I chickened out and didn't go for four shots.

This points to why I am so curious how fast doubles really are. Its tough for me to imagine getting off a second aimed shot much faster than 1.5 seconds with any big bore firearm.

Cheers,
Canuck

Canuck-I'm going to repeat the test with my 9.3X74R SXS next week and also compare it to my 450 Ackley or 470 MBOGO. The O/U is definately slower than a SXS and easy to hang up the action if the lower case doesn't seat. 4 aimed shots under 7 seconds is not too shabby with any kind of gun. I'm gonna have to put a shoulder stock on my .500 S&W to beat those times.-Rob. -Rob

Last one...

Dave also has a video of him shooting three fast shots from his 470 Mbogo. You can see it here.

This one was intended to demonstrate that the recoil on a 470 Mbogo is manageable. It does not verify the accuracy of the three shots, but you can see that Dave has the rifle under control before shooting again.

The time for the three shots are as follows:

Elapsed time from first shot to second shot: 1.53 seconds
Elapsed time from first shot to third shot: 3.62 seconds.

Dave was blazin' fast on this one

, and its cool video too (facing the shooter).

Cheers,

Great videos Canuck. Thanks very much for posting. Let's make sure we get some doubles. We know how fast a bolt with a full mag can go.

The primary consideration of speed with any rifle or shotgun is gunfit, balance and stock design.
These factors combined with appropiate weight for caliber will allow for the best "control" over the firearm.
Then practice and familiarity will lead to smooth gunhandling = speed.
"Try" to go fast and see how things stuff up - keep smooth and be surprised how little time is taken.
Practice the processes slowly and get the movements required economical and precise.
Once we have done this the subconscious will come into play and do the required job.
Give it a try - dryfire with dummy rounds etc and I guarantee this method works.
