I talked to a friend of mine and he said he had just recently bought one and said it helped his group out alot at 200yrds. does anybody use these things if so how much does it help. i have a 22-250 26" bull barell, cheap remington synthetic stock, bedded and free floated, trigger adjusted down not sure on lbs but light enough for me. get some good groups alot under .5" almost every time. would it help tighten my group and keep it more consistant? also i shoot a 300wby and it shoots .5" groups all day long. i hand load for both rifles just want anybodys in put on these cheap things?
