Anybody used these? Real interested in the 160 grain 7mm bullets. That bc is crazy for a mono. Wondering how accurate that is and if mag feed vs single feed really doesn't have poi shift. Also curious about performance on game.

Probably cost prohibitive for most people. Even if your forced to shoot leadfree there's much cheaper options

Agree on price, to me $2.50 per bullet is way too steep for something with little data provided. Estimated BC...how so, from drops, or with Chrono data? If they are a true long-range bullet, how about impact testing at 1600fps instead of overbore magnums with 2200+fps at impact? Do they shed nose/petals at high speed or just mushroom like a barnes at all speeds? Why does the magazine-feed version "have less range" than the single-feed, is the design affecting BC and is the terminal performance/impact velocity altered?

Add “minimal expansion test” that is using water. Water, which shows over expansion/the maximum expansion you will see. Measurably more than muscle tissue and vital organs.

The videos explain some of this. And I get the cost being high, but I'm still curious about real world experience. Supposedly the single feed are softer for lower velocity impacts and the mag feed are a bit harder. But like others have pointed out, that makes me wonder how similar they are in terms of poi.

Hey Sam. Are these bullets easy to load for? Are they finicky at all with seating depth?

I've been asking a few questions on here and couldn't get anyone with experience to chime in. My understanding is Ryan Avery may have some experience, so hopefully after season he can add something. I'm curious if bcs have been verified via Doppler yet? Is there a poi shift between mag feed and single? Is there anything someone would need to take into account in loading these like reduced powder or something?

The BCs have not been doppler tested. We
do drop tests and run them through different ballistic programs. BCs have held up with many different testers.No poi shift between single and magazine feed bullets. Identical profile. As far as loading I can't give recommendations but in my guns it has been in the middle of the pack as far as powder charges. I am available for calls to get as much info out as possible.

30 Sherman mag, 195gr going 3050fps. Used .700 G1 for bc. This shot was at 700’ elevation and 981yds. Sure looks like they work to me. Bullet was found on offside hide through shoulder. So close to exiting, it actually punctured a hole with blood on the outside of the hide. Impressive.

That's interesting that you can get the BC's that high with all those drive bands/displacement grooves. What do you do different with the drive bands than say barnes or hammer? I realize yours are longer with a sleeker overall profile, but you normally get a ton of drag out of those bands.

Also, it appears these have hollow cores to some extent but no hollow point at all on it? The pics make it look like an FMJ if you will, but you're clearly getting expansion. Care to explain what's going on there?

Can you go into detail on the magazine vs not? Is there a separate tip on the magazine fed bullets?

We have been very conservative with the BCs and people have been suspicious of them until they shoot them and verify for themselves. I'm not going to get into much detail but every part of this bullet has been optimized. Feel free to contact if you have any concerns.

It's not concerns, I genuinly would like to know how you're doing this better than everyone else.

I'm not going to test them at $2.75 per bullet unless there's a LOT going for them. The other niche copper bullet manufacturers are really transparent about their process, alloy selection, how they intend the bullet to work.


I'd suggest that approach, but you do you.

I can vouch for these bullets having reloaded and hunted with them for 3 years in a variety of rifles from 6.5x284, 280AI, 28 Nosler, and 300 win. They have expanded on all game from antelope, deer, bear, bighorn sheep and elk at close range < 100 yds and long ranges to 650 yds. I have shot them at steel & rocks out to 1100 yards at the estimated bc’s.
I think you like them.
