Nielsen Specialty Ammo .457 EPP Slugs
« on: February 20, 2016, 04:37:58 PM »
Nick at NielsenSpecialtyAmmo.com was extremely kind to send me a bag of .457 EPP Slugs in 168 grains to give a go in my still not broken in Sam Yang 909s.

I took a handful of the slugs and ran through my .457 sizer, and there was almost no resistance at all, and they all felt the same, leading me to believe I'm probably wasting my time sizing them. But it's what I've been doing with other .457 bullets I've been trying. Other cast .457 slugs have been all over the place in size, and a few require a lot of effort required to get through the sizer.

I have some EPP-UG Airgun slugs I got from http://www.whyteleatherworks.com/BigLube.html and they are about the same size, and look almost the same. The Nielsen slugs have a 2x wider front ring than the Whyte's, and I think the Nielsen's have a little better quality cast. Both have some tiny defects, but nothing that I think will affect accuracy.

Filled the 909s up with air, and set up the Chrono, and my two layers of duct seal putty silent pellet trap (made with 2x lumber). Shot off 4 shots initially to sight in the rifle, then filled up the rifle again with air, then fired off 5 more shots. Chrono gave an error for the fifth shot of the second set.

Niesen Specialty Ammo .457 EPP Slug - 168 grain Results:

First set to sight in rifle.
1. 739.1 fps
2. 721.4 fps
3. 682.1 fps
4. 652.1 fps


Second set to test accuracy.
1. 751.9 fps
2. 724.2 fps
3. 695.6 fps
4. 662.0 fps
5. error

Now I will have to admit that I spent 3 hours this morning doing Jujutsu and my whole body is aching, especially my arms. One hour was spent swinging around a "Jo". My arms felt like rubber as I was cocking that rifle and then taking aim. But considering the rubber arms I think the group is pretty good. Yeah, I know, 50' ain't squat, but that's what I have to work with.  I had fun for that little bit of time, and am excited to get that 909s out in the field and stretch out my distance. And given I have a nice tight group at 50' I see no reason why I won't get a nice tight group at 50 yards.

I found my ammo that the 909s loves. The round balls are ok, but not nearly as tight as the Nielsen EPP. Ohhhhhh Nick, I'm wondering what a nice round number would be for 500 of these things?  8)

One thing I've noticed about the 909s is how hard it is to load the ammo. You really can't get the slugs all the way in the breech, and you end up with perhaps 1/8" sticking out. But the 909s doesn't really care. It fires off the slugs just like it's meant to.  So no worries.

Note: My silent pellet trap stopped the .457 EPP Slugs, but at the cost of splitting the 2x10 redwood I used for the back wall of the trap. Bah... Back to the drawing board on that.

Based on my rather short set of tests, I am convinced these are some mighty fine .457 slugs that the Sam Yang 909s truly loves. I'm a gonna order up a bunch.  Niesen Specialty Ammo .457 EPP Slug

Thanks for the write up.  Glad you liked the slugs.  I already sized them to .457 before sending them to you, they come out bigger than that out of the mold.

I now have .457 ~265 grain slug I need to test but need something with power like a hopped up 909 or a Texan to push something that heavy.

Being new to casting and selling in a larger bulk than my swaged stuff I am not sure how many people want to buy at a time.  I put pricing for 100 and 200, I am sure if you want to do 500 we could work something out.

Thank you again for the review.

Great grouping and a good weight for the 909 and its power level.

Nick, The weight of these is really appealing for my 454 Dragon Slayer gun.  If they shoot good in my Dragon Slayer 454, i will be buying plenty.  I DON"T CAST FOR THE DSlaye :-[

I will email ya..............

I shot these in my Texan today. 950fps and 50yd groups were 3/4" C-C. And obliterated a 1/2 gallon frozen milk jug. Clean pass through. First time shooting the Texan and 360ft lb with these is devastating.
