🇦🇺😎👍I brought about 5000 Remington pistol primers about 6 years ago and I had about a 10% failure rate…great video🏁big fella🏁

Really like the format of your videos, straight up to the point. Don’t suppose you chrono your load development? I’d be interested to see how groups correlate to velocities

[@2clicksup910]

Firstly, thanks for the positive comments. I have never chronographed anything; I avoid chronographs, as they can (and often do) fill your head with too much information. I vividly remember remember back in my old Trapshooting days and speeds wet staring get printed on boxes; shooters were driven mad in the quest for the perfect speed. They became obsessed and believed 25 feet per second was the difference between success and failure. That speed difference was equivalent to a clay target travelling about 10-12 inches, and I always said that if that was your difference between a hit and a miss, maybe you’ll should consider another endeavour.

Id maybe redo the 53.5gn of the 2209 & the SST. Just to see if it was you that made a mistake on the flyer. On your previous 22" barrel the SSTs worked a treat better then the currant barrel IMHO, maybe because it was well run in. If you did favour the 130gn SST id go back to those. The HPs are more for maybe roos & goats, the speer SPBT might be abit hard, where the SST is somewhere inbetween. Before i rebarrelled my CMC 270 it had just a std 22" barrel, it shot best with most projectiles 53.5 or 54gns 2209.

That does seem to be something like a “sweet spot” for that weight projectile, so I think that’s where it’s going to end up. It was the first day out with the new barrel, with a lot of shots fired and the barrel getting quite “warm” at times. I’m quite confident that barrel will settle down more as time goes on, and the large number of rounds and high-ish barrel temperatures are both situations that would rarely occur in the field, so I think we’re OK at this stage.

why didnt you just go a stainless barrel just wondering

[@2clicksup910]

At the time I did it, stainless was in something of short supply. As it turns out, I’m more than happy with the end result…
