Testing with new bolt nose and BP from Elkman
After listening to Carl………Elkman, bust my gonads about sticking Fed. And CCI primers, I finally relented and sent him my barreled action to see what he could do.
Mind you, I had NO, ZIP, ZERO problems shooting Win. 209’s in this rifle with ANY loads and NOT having a problem with sticking primers.
So, he built a new bolt nose to his design (does not have that recess in it like the Hunter bolt nose and opened the dimension on the slot. The BP was built to have a more crush fit with the nose of the primer. Carl sent some ten rounds down range with both CCI and Federal primer with no sticking.
Yesterday was the first I shot it since getting it back. Carl does nice work and if you saw those pictures of the pedestal bench rest’s he makes, you would know why. So, the burning question is:……………do the CCI and FED. Primers stick??? NO! But are these primers all they are cracked up to be? IDUNNO? For one thing, the CCI’s still show signs of leakage up along ¾ of the sides. The Federal had never shown leakage but did stick………..And the Winchester look just like they did before the “operation!” Again, no sticking by any primers with straight and duplex loads.
Oh, BTW, that damage to the front photo cell on my PACT chronograph? That is what a .060” veggie wad will do at 10’ from the muzzle driven by a 10/60 --- Clays/H-4198 duplex with no bullet. Man, the report sounded a little different but still had a good BANG to it. I forgot to load the bullet and just pushed down the wad. I wondered why I got no reading on the chronograph and no impact on the target. Did not see he damage until I was done shooting and packed up the chronograph.
Carl is a big proponent of using wool wads behind the 300 gr. SST with around70 to 73 gr. of IMR 4198 so I did want to try the combination along with the Fed. Primers.
Starting with a clean barrel I shot three fouling shots on the red bull attached to the Pittman target. These are nice targets and give you many aiming points to use and are made of some thick type of paper. Kyle has them on his web site. I have a lot of my own targets I had printed on card stock so these will be used intermittently for the time being.
Note the first shot much higher in velocity than the next two.
The second group was with 72 gr. of H-4198, a wool wad and Fed. Primers. Note the second shot about 165 fps slower than one and three? Wool wads???
Group #3 used this same 300 gr. XTP with Win. 209’s and veggie wads on the first four shots then wool on the last three. Velocity decreased over 50 fps when switching to the wool wad. POI also changed and went a bit lower. Why was shot #1 out of the group? Maybe the switch for the single powder charge to the duplex needed a fouler? IDUNNO? The velocity was a little lower but at 100 that should not have made a difference? Another reason I favor shooting more than three shots. It is not always the first three that group together?
Moving on to Carl’s exact load (give or take a grain or two), It did not set the world on fire for me and my rifle. It did average 2667 fps with a nice 20 fps ES. These guns are all different and what works in yours may not work in mine!
While I was shooting the straight charge of IMR 4198 I wanted to shoot the three 300 gr. AccuMax’s I had brought with me. Here again, I wished I had at least two more as the first shot was out of the group formed by shots 2 and 3. Maybe I needed a fouler going from a Hornady bullet to the AccuMax? All things that go thru my head!!
And lastly, back to my old reliable 10/60 Clays/H-4198 with a 300 gr. SST with a veggie wad and Win. 209 primer. Here the first four were really nice at .728” but the sombitch fifth one?
? Dropped 2” out of the group? That crosshair was dead nuts on the POA just like the previous four. The bullet loaded exactly the same and the velocity was right where it should be. That caused some foul language, let me tell you!
My explaination? “Bullet Integrity!” A factory pistol bullet shot at twice its intended velocity and being spun way faster than if fired from a hand gun. Any defect or imbalance would be greatly magnified. It could have just as easily landed high or right or left?

Elkman: They do not stick but they still stink with the wool.
