I couldn't stand waiting around any longer for my tang peep to come in so I grabbed the Hawken with the new .54 GM 1:70 twist barrel. Now I realize why you guys like these so much. I never was a .54 fan - until now.
First target I dialed in the sights. First shot high right was entirely my fault. The shot went off before I was set. The next ones were low and did a few sight adjustments. Target was set at 50 yds.
First load attempt was 90 gr of FFg/.015" Ox Yoke patch - 3 shots; 0.72". Not too bad for a virgin barrel.
Second load was 80 gr of FFg/.018" pillow tick/bore butter lube - 3 shots; 1.32" Ok Not too impressed.
Third loading I went back to 90 gr FFg/.018" pillow tick/bore butter lube- 3 shots; 0.45" Now that is pretty awesome for iron sights.
I was fortunate that I stopped at the gun shop and picked up some .530" balls. I tried loading .535" balls and they were waaay too tight. I had to literally pound the first one down the bore. Even the .530" were tight but loaded fine even with the .018" patches.
At this point I was low on powder so I had to quit. Next time out I am going to try the pillow tick with olive oil. And I will adjust the sights a tad to the left.
