Yeah!!!
Back from the range. I gotta tell someone.
I had been chaseing the paper patched boolitt hitting at least the berm for months.
Today, today, I got a five shot, 3" group at 100yds!
C312/185R Lee Mold, sized .308.
Starting load for 4895.
THREE wraps of Meade Traceing paper.
Large rifle primers.
I had gotten so shy of my loads, that I only made 20 this time. I had on hand 20 other sized .312 with paper. These I smeared lightly 400 grit lapping compound. I originally figuired, I would fire the lapped ones, fire the thicker ones not expecting much.
The lapped ones were not on the paper, however, they were real close. I fired those off. The barrel is showing less tool chatter marks inside it now.
I chambered a paper patched one at .3135. Set it off. First shot, within inches of a random bowling pin on the berm! Dang. The next one hit the same spot! That hadn't happened before.
I had put three pie plates on the stand. I fired at the center one. One on the edge. I was not even able to hit the berm before!
I fired the last 20. I got some serious groups. As the barrel heated up, the group changed. I had not bed the barrel yet. Cold, they are dead on as sighted with the scope for milsurp.
Firing the paper jacketeds, it is like firing a .22. You can feel the difference between the jacketeds and paper. The jacketed is sized at .311. It does not feel right. The paper feels solid when fired. Very little recoil, relaxed point of aim.
Once the barrel got hot, and it did indeed get hot, groups went out the door.
Untill that point, at least as good as the milsurp I had fired before.
I am going to try, two wraps of notebook paper. That gives with the casting sized at .311, .314 dry. Also the three wraps of meade making .3135. I will be also doing some serious bedding before the next session.
So, what did I learn?
Lapping compound, smeared on loose fitting paper patches makes the barrel shine. Worked real well.
Tight patches to bore work real well.
Today, jacketeds did not fire as well as paper patched. I loaded both the same amount of powder.
I had my wife look for confetti.
None. No evidence of paper patching aside from seeing the loaded shells.
I use water quenched wheel weights.
I do plan on trying paper patched zinc one of these days.
Last time at the range, people were watching me. This time, people were gathered around me.
Last time, they offered advice, this time they asked questions.
Dang, I feel ok about this.
I will say, if it hadn't been for this forum, and the folks here, I would have thrown in the towel long ago. I am glad I did not. I would have missed something really special.
Thanks to all of us.
We hung in there, and it worked.
Yeah.
