Lots of good standing work to be done at 25.
I frequently run the 20 yard portion of the “Half and Half” at 25.
Initial Drill:
5x8 card, placed vertically.
10 second par time.
10 shots from a standing low ready/alert.
When you are consistently passing, reduce target size to a 4x5 card, oriented vertically (just fold the 5x8 in half and/or cut it in half).
When you are consistently passing, reduce target to a vertical 3x5 card.
One drill that I had to do for a competition overseas was a pretty good one as well. Modified here for your training pleasure:
3" circle at 25 yards.
3 second par time.
Goal is 100% accuracy.
Starting position: Standing alert
Intro: 2 shots/2 hits in 3 seconds.
Beginner: 3 shots/3 hits in 3 seconds.
Intermediate: 4 shots/4 hits in 3 seconds.
Advanced: 5 shots/5 hits in 3 seconds.
Just keep working to get as many hits as you can in the 3 second par time. This is a great drill to work on a fast, precise presentation and recoil management.
The Cabbage Patch:
Shoulder transition drill.
5x8 card placed vertically.
3 magazines of 10 rounds.
No time requirement, priority is placed on smooth, secure hand positioning, safety engagement, manipulations, and accuracy.
Starting position: Standing alert.
Fire single hit from dominant shoulder. Move selector to “Safe”.
Transition carbine to support shoulder, leaving hands in place (support hand on handguard, dominant hand on pistol grip, stock in support side shoulder, aiming with support side eye) and fire a hit. Engage safety.
Move hands to a “traditional” support side grip (move dominant hand to handguard, just forward of support hand, and then move the support side hand back to the pistol grip) and fire a hit. Move selector to “Safe”.
Without changing hand position, move carbine back to dominant side shoulder and fire a hit. Place selector on “Safe”.
Switch hands to traditional dominant side firing grip and get a hit. Place selector on “Safe”.
And so on.
When you run out of rounds, perform reload from the position that you are in when you run out of rounds.
You can switch the drill around to keep from falling into a rut:
Fire 2 hit per position instead of a single hit.
Switch up sequence of hand changes, i.e.: go from traditional grip to reversed hand positions before switching shoulders.
Randomly fill 3 to 5 magazines for use during the drill to force reloads from different positions.
Notes:
If you are uncomfortable with the reverse grip, it helps to allow the hand on the handguard to move further rearward than normal. You can also just do traditional shoulder transitions and leave out the reverse grip until you feel more comfortable with it.
If you have never reloaded from the support side, or if you just want to work on the mechanics of the grip/shoulder swap, it’s fine to limit the string to a single magazine (normally 30 rounds, but if your range only permits 10 rounds in a mag, then go with 10 rounds).
Safety is engaged prior to ANY and ALL hand or shoulder transitions.
Dry-fire this before going live.
Modified 400 point Aggregate.
B8 Target (I use 2, one high and one low. First 2 strings are fired on top B8, last 2 on bottom B8) You can just get the reface as nothing outside the “8” ring will count for score.
All strings of fire will have a par time of 30 seconds.
All strings of fire will be 10 rounds and include a reload after the first 5 shots.
Starting position for all strings of fire will be the standing alert.
First string: Standing.
Second string: Standing to kneeling.
Third String: Standing to sitting.
Fourth String: Standing to Prone.
Upon completion ensure that all 40 rounds are accounted for and conduct scoring. Score as indicated, except that any shot outside the “8” ring counts as “0” points, or “-10” from possible.
This drill will give you a consistent reference point for measuring performance.
If you have 100, 75, 50, and 25 meters/yards available, you can simply shoot the “normal” 400 point Agg though, which I prefer over the 25 only modification.
Have fun.
