Spent a little testing some loads this morning and thought I would share them.
7.62x39 with 165gr LBT, LFN sized .314” 5shot strings
All loads fired in Mini-Mauser, 20” barrel
Use any load data at your own risk
1. 11.5gr/1.0cc dipper of bluedot averaged 1528fps with a SD of 28.3
2. 13.5gr/1.0cc dipper of 2400 averaged 1590fps, no SD as I hit the clear button early
3. 26gr/1.9cc dipper of IMR 4895 averaged 1828fps, SD of 34.7
4. 24gr/1.6cc dipper of Data 68 averaged 1930fps, SD of 15.1
5. 4.6gr/.5cc dipper of Unique averaged 853fps, SD of 13.7
6. 17gr/1.3cc dipper of IMR 4227 averaged 1810fps, SD of 35.4
Data 68 load proved to be the most accurate, 3 shots into less than a ¾” square with two other shots shots opening group up to just under 1.5” center to center. DP-68 also had the lowest SD. Groups fired at 100 yards with only a 3 power scope and shooting out of my truck window, not a really bench rest. The 4895 is the next best load with 3 shots in a tight cluster and two other’s opening things up to 2”. The Unique loads also shot very well and would be a good bunny/squirrel load. The three remaining loads all produced about 3”-4” groups, so it seems that I need to do some experimenting and find a midrange load(1400-1500fps) that shoots good. Bullets were lubed by dipping into lee Alox thinned with mineral spirits, two coats applied. Bullets seated just to the rifling. I am very happy how the new boolit shoots.
