a few pics of some groups from surefire .25 round nose…
…bullets.
Jerry was kind enough to send me 50 to sample. I shot them out of my AAA .25. (This rifle has achieved a high of over 100 fpe with surefire slugs).
I was very impressed with the potential of these bullets and I will buy more to continue testing. What I found in my results can also be said of what I found with the surefire six or seven rings.
My first five shots are always the tightest group. As my fill pressure dropped, my subsequent groups began to open up. The faster I can move these bullets, and the surefires…the better they group.
My starting fill pressure on these groups below was 2900 psi. My hammer preload spring is set on 7. My next test will be with the preload maxed out and a start pressure from 3300 psi. I will work my way down if I experience any valve lock.
I am very impressed with how tight these bullets grouped on the first grouping. See for yourself. Groups were shot at 35 yards.

Those round nose slugs are the same ones Roach was making for himself before his mold was destroyed during modification. I think we’ve learned how to cast then consistently to reduce bullet caused flyers. We’re going to sell them at the same price as the ring slugs. Now, if we can get joe to chrony that first group, we’ll know how fast they like to fly.
hey 80, what’s the muzzle velocity? how much is Jerry getting for these? inquiring minds want to know.
Thanks 80 Grit, I feel so much better now, LOL and these slugs look really nice and the weight, I think I could hurl them quite fast. Even if you get 5 good shots it would be great for a hunt.
Didn’t take any but since you guys are so special I came home after a 14 hour shift at work and reached for the camera before anything else. They weigh 53 gr. I am going to get them moving a little faster so I can get those subsequent groups looking more like the first group. I hope I have at least 3200 left in my tank otherwise I need to plan a trip to the firehouse…

This is new to me round nose when did these come out? maybe I don’t get on enough and like synopsy what are the weights?

Nice groups though… 😉
Tight groups…perfect for that coyote you are after…

Jerry,
I think I have around 10 of them left. I will chrony them on the 2900 SP to see how fast. I won’t be able to get to it till sometime on Tues…if not, my next chance will be on Thursday.
Joe
