I am really thinking about reloading for SD purposes and was trying to decide on a projectile. I am going to list what i have come across and my findings. Please let me know if any of the assumptions are correct. Hornady XTP= great all around, but to me it seems not enough expansion but great penetration. Golden Sabers= ok round but hear too many reports of jacket separation when pushed Gold Dots= Great expansion and penetration. Trying to decide if i should look for 165 or 180s for Glock 20 with extended barrel. I have seen the 165s perform better in a g29 since a little slower the petals dont seem to fold back as much. I am thinking that the 180s pushed to 1250-1300 would do the trick. Nosler JHP= Seem to get great expansion and reviews over all and price is very reasonable. Barnes= great except at close to a $1 a bullet it is way too much for my taste So please share your opinion the above. What are your thoughts between the GD 165 vs 180. And also your opinion on the Nosler JHPs. Would a 155gr XTP pushed 1400ft/sec expand better than 180XTP at 1300ft/sec?
