My rifle shoots good after removing the QLA. I used the tubing cutter as described by
Semisane to mark the barrel. This evidently works to keep the cut square; my rifle probably wouldn't shoot good if it didn't.
The pictured target was shot at 47 yard before the QLA was removed. The numbered holes were made by a 500g Conical cast by
Flounder They scared me so much i shot 3 more times using the 300g Deep Curl, just to see if something wasn't haywire. Those holes are dyed green.
After seeing how them conical shot in the rifle, i cut the QLA off .
Then i tried shooting them 500g conical again using the rifle now without the QLA.
The holes near center were shot at 100 yard. The holes dyed green were shot at 48 yard.
Then just to see if the rifle could still shoot the 300g Deep Curl in a sabot, i shot them at 200 yard a week or two ago. The following target is the result.
Semisane' technique works.
