Few things on speed of firing and let's agree, it takes practice, training. Something that most war time soldiers didn't get.
In the use back in 50s through 90s (?) they shot service rifle competitions with bolt guns and M-1s (M-14s) before the AR invasion. Bolt gun catagory was a bit loose, yes you had to use the 30-06 or .308/7.62x51 cartridge. NO it did not have to be a 1903 or 1917 rifle, 11lb Winchester M-70s with very fancy sights and very nice triggers were allowed, just use a 5 round magazine feed by a stripper clip.
The rules allowed 10 more seconds for the bolt guns than for the semi autos.
200 yds rapid 10 rounds sitting was either 50 seconds for the semi-auto or 60 seconds for the bolt guns.
300 yds rapid 10 rounds prone was either 60 second for the semi-auto or 70 seconds for the bolt guns.
Semi autos were loaded with 2 rounds and then reloaded with 8.
Bolt guns were loaded with 5 and 5.
Time started with the targets in the pits (if the ranged was set up for it) and the shooters standing, crouching, or imitating a pretzel.
Shooters had to drop down into their desired position for sitting (or for prone) which often took about 20 seconds to start shooting.
when the initial load of ammo used up the semi auto gunners either stuffed a an 8 round clip into the M-1 or changed boxes on the M-14.
Bolt gunners used a 5 round stripper clip.
This often took another 10 or more seconds.
Good bolt gunners could fire about one shot every 3 seconds.
Semi auto gunners were a bit faster. I was couched to count to 4 between shots. fast count

to keep form shooting too fast.
targets changed from the 10in A-5 to the 12in SR target during that time. A5 was a 5 - V scoring system, hit the black and you got the 5. The SR target black included the 9 ring.
This was for 200yds. At 300 yds the SR target was enlarged to 18in but the black now included the 8 ring. The 9 ring was the same nominal 12ins.
Everybody used slings and shooting coats and gloves.
We had better sights (gas guns had their front sights cut down to the exact width of the black instead of being too wide like service sights) and most bolt guns shooters used an aperture front sight. Put the ring around the black.
If you are over about 22 years old trying to use a Mauser, or Japanese or Italian or French rifle is NOT going to work. Trying to use what ever front sight they are using with those little V notch rear sights was too much of a handicap unless you have 20/20 vision (or better). The Enfield No 4 with the good rear sight may be doable.
Now this was target shooting and the good shooters were keeping everything in the black or at least 8-9 shots in the black and perhaps they kept them in tight enough to make up for the one 8 or 7 on the SR target.
We also were shooting on a buff colored target that was over 5 ft tall and close to 4 ft wide with that black dot in the middle, not some soldier trying to hide next to bush or tree or wall in crappy light. We also were at known distance. Not guessing if the target was at 280 yds or 340 yds or????????
Nobody was shooting back either.
If you have crappy sights and poor light you need to take more time with either gun. IF all you want to do is hit that 5ft by 4 ft target you can shoot really fast (although I have seen people only get 5-6 hits on the whole paper when beginning)
What some guy can do on You-tube in a demonstration is not what most people can do, I have been driving for over 50 years, doesn't mean I can drive a race car at over 120mph on an oval track.
