I finally got to the range today.
I used 4 long guns in the test (from left to right): Mossberg 500A, Marlin 1895GS 45-70, LE No.5, BRNO 602 .375 H&H
Here is a video of the Marlin 1895GS. The ammo is Federal 300 gr factory so it is very low power.

Here is the 45/70 group:
Here is a video of the BRNO 602 carbine. The ammo is Federal 300 gr factory ammo. It is not low power

but is still easy to control offhand.

Here is the .375 H&H group:
Here is a video of the Mossberg 500A shooting 2 3/4" 1 oz slugs. Even though it was difficult to extract the empties, it had the fastest elapsed time. The 6" group is pathetic but I am very wary of that short Choate stock. If I get a good cheek weld the hinge of the stock is very close to my nose and results in a good smack with slugs. I'll probably switch back to the OEM stock for better accuracy.

Here is the horrible 12 ga group:
Here is the video of the LE No.5. I had probems chambering the 2nd round of factory 170 gr softpoint ammo. It is coming off the left side of the magazine and hung up on each of the 3 strings I shot. You have to really hammer the bolt forward to get the tip of the bullet to slide up the ramp. Has anyone else seen this problem? Perhaps the OAL of this factory ammo is too long.
I don't think that the slow time is representative of a normal No.5 with good ammo.

Here is the .303 group:
The results are as follows:
1895GS, 4.52 seconds, 1 7/8" Score (Group size x time): 8.48
BRNO 602 6.58 seconds, 2 1/8" Score (Group size x time): 13.98
Moss500 4.11 seconds, 6" Score (Group size x time): 24.66
LE No.5 8.39 seconds, 2 1/2" Score (Group size x time): 20.98
Predictably the pump was the fastest, even with extraction problems. But I was less accurate with it due to the stock and the bead sight.
This was a valuable lesson for me as I had planned on loaning the LE No.5 to a friend who will be working in Northern Saskatchewan this year. I will resolve the feeding problem with the JC before I lend it out.
I feel confident with both the 1895GS and the BRNO 602. Either rifle will do the job at close range.
But man I gotta speed up a bunch if I want to get close to Camp Cook.
