First tried it about 6 months ago after a few people had last comment on it. Easy draw weight than 1745 and boy it sends 8mms steel fast, however it is noisy compared to other tubes which was a big turn off for me. I shoot bareback style and over the last few months 3050 has real grown on me to the point where I take it out all the time now. I use a 14" single loop mainly shooting 8mm steels and 10mm clay balls, however I have used 8mms leads on occasion and have been very impressed. In the last few weeks I have put a few 10mms leads out and was quite shocked at how far it would send them and their impacted????. Longevity so far seems good well over 500 shots with no sign of damage or dip in performance.
3050 seems to me to be well behaved and versatile tube. In the future I will be looking to try 1/4" leads but am still looking for a mould at the minute, don't know about cold weather performance but will find out in coming months????
