Back from the prairie, we aren't golf ball mortar newbies any more! We experienced the same huge variation in range that others have written about. Our Mallet's mortar junior GB mortar worked very well; no problems with it, just standard learning curves issues, that's all. We fired 7 shot for practice and 7 for record. For once the wind was nil; no excuses due to wind. Darn!
We tried 15 grains of FFFg first with 45 degrees elevation. The ball went 40 Yards over! We tried 11 grains next; only 15 yards over. 9.4 grains was next for two shots. We had 4 yards over and 9 yards under. A thin paper patch with 9.4 grains yielded 30 yards over! We tried 60 degrees next and found more consistent results with a 9.4 grain scoops slightly rounded. We stuck with that and got the following;
SHOT No. Distance from Dowel Vector from Tube Angle Charge
Dowel

2. 10' 5" 2 " '' " "

4. 46' 2" 12 " " " "
5. 15' 4" 6 " " " "
6. 8' 9" 1 " " " "
7. 65' 7" 1 " " " "
Aggregate minus shot #s 4 and 7. is (59' 6") or 714 inches.
Well, we sure did have fun, even if we didn't place all the balls into one gofer hole.

Mike and Tracy
