I played with the Crosman DPMS a little bit today.

I chronographed eight 25 shot strings. 68°F in the basement.
I shot each 25 round magazine with a 3 second delay between each shot and reloaded each magazine promptly and continued firing the next mag.
Mag 1. 373 fps ave
Mag 2. 357 fps ave
Mag 3. 346 fps ave
Mag 4. 335 fps ave
Mag 5. 327 fps ave
Mag 6. 332 fps ave
Mag 7. 312 fps ave
Mag 8. 297 fps ave

Mag 9. the velocities dropped significantly with BB's flying errantly.



dust cover opens and closes...bolt holds open after last shot



the upper and lower receivers separate







magazine loaded using provided speed loader





you have the choice of using 1 or 2 CO2 carts



25 rounds semi auto rapid fire left target...25 rounds full auto in 5 shot bursts right target...6 yards offhand



 
I found some targets on the UBC Comp site that will work well for me to practice rapid and full auto fire with the Crosman DPMS.

starting position with gun down at a 45° angle

using a count down timer

targets at 6 yards

8 second time limit to burst shoot each man with a minimum of 4 hits


20 second time limit to tap 3 shots into each man


3 second time limit to acquire target and dump 25 round magazine


Also did a couple of runs on my shop built reset-able pin rack. Can never have enough practice to get tuned up for pin shooting with powderburners :) First run was 3.53 seconds and 3.56 on second...room for lots of improvement.
