[QUOTE="cape cove, post: 2192106, member: 95503"] I have read in several articles that plastic tips don't have much of an effect on stability. I most certainly don't agree with this as I have had 2 different experiences with plastic tips and stability that lead me to think differently.. A few years back I had a 22/250 with a 14 twist. I thought I would be good for all bullets up to at least 55 grs. I purchased a box of Hornady 53 gr V-max, loaded and shot some. Right away I knew I was in trouble because the bullet holes were oval and accuracy was bad. I got in touch with Hornady and was told that a 14 twist may not stabilize this bullet. Having 80 bullets left and no other 224 rifle to shoot them in I decided to experiment with them. I cut the tips off taking them from .830 to .711 in length . No other change. I then proceed to shoot the same load. The bullet holes were nice and round and accuracy was .75 MOA. Not benchrest accuracy but decent none the less. The next experience I had was when a friend purchased some Barnes 168 LRX for his 9 twist 7mm Rem Mag, not realizing it required an 8 twist. They didn't work for him and he asked me if I wanted to try them in my 7/08. I loaded some up for my 9 1/4 twist 7mm/08. The load was 41 grs of H-380 WW primer in a RP case.

This was the only changer I made and the accuracy went from a pattern to one of the best groups I had ever shot with this rifle .340 . This is just my experience which led me to believe that plastic tips have a serious effect on stability and accuracy. [/QUOTE]
