Speed kills is the mantra nowdays for bullets. In the discussion about twist rate I decided to experiment a little . I chose one of my fast twist guns. it is 1:18 twist. Normally I shoot either a 500 gr lead bullet or a 405 gr lead bullet. For this experiment I chose a 300 gr jacketed hollowpoint, knowing the gun doesnt shoot them very well . But what if I slowed them down some. Would that help.?
I went with loads that according to my program would give me about 1200 to 1300 fps max. ( just a guestimate)
The wind was 19 mph with gusts even higher so I decided to do all the shooting at 50 yards .The gun is sighted in at 100 yards.
The first bullet which was 200 gr lighter than normal and 50 yards closer shot high. That's the top hole on the target.
I didnt want to change my sight so I just held under the orange a hair. it put 2 in one hole



I was shooting without a steady rest, like hunting conditions
the next group wasnt bad but it did have a flyer



then I decided to try 6 shots as fast as I could. , the barrel was really warm. You can see the results



Overall I came to the conclusion that I could shoot even light bullets in a 1:18 twist if I kept them slow . They would still be deadly on game and produce hunting accuracy.
This was all done with open sights. The bullets were .459
