We are working on the 177 production. Our HP pins right now are a problem in the manufacturing process - breaking. I machined new pins and had them heat treated. I dropped them off at the grinder and will be a few weeks until I get them back still. These pins are held to +- .0001 so I can not hold that on my machine and the bottle neck is the grinder.Once we get them back we will restart our testing. Results so far looking pretty good, like any ammo, some guns love em and some don't. Should restart testing mid April but the shutdowns my effect that well.

However, if breakage persist, I would suggest S-7 as it has very high impact resistance, and torque resistance. If yo are using any type of stainless what so ever, Don't there is no true stainless hat has superior shock resistance other that the exotics which are not true stainless Steels although marketed as such. These are 154-cm. ATS-35 154-CPM and Powdered metallurgy D-2 and D-4. Knife/Mike
Scott, your knowledge of fine accurate pellet shooters is beyond approach. If I were searching for a very accurate combo, you would be #1 on on my list of the people who know exactly what they are talking about thru you vast experience. It would no doubt strike you a little odd If not down right insulting if I told you sure Scott, but I have to call JSB to see what the real truth is. LOL! Particularly in an application they have no experience in what so ever. this is pretty much where Travis left the conversation. Odd, considering my experience on the subject, and Nicks lack of same. Not disrespecting Nick, he is just now venturing into .177 slugs. At this time, Tofazfou is the first I would consider consulting on the subject. Luckily, he and Nick are friends as well as is Dyotat100. I will fully admit, the listings of the TJ's can be confusing. There is really no reason you should be up on it as it just isn't what you normally do. (Although it seems you may very well be about to be.) For those wanting to shoot the forthcoming NSA .177 offerings in the .172 slug barrel, it is an easy matter to futher size down using the NOE System. Easy-Peasy. The catch is the twist to length ratio. (not the weight), Only by testing will we learn the feasibility of them in the actual slug barrels. I have simply got to find room for a small lathe. I have a TJ's here in .172 that I need to fit in the Mini. Knife/Mike
