Thank you, appreciate the effort - Sierra Game Changer's should be useful bullets for me, especially when the data includes Re23 for the 6mm Rem

Did an OCW and seating depth test in my 260 Rem 1:8 Sporter 22” Lapua WLR. Accuracy was, at worst, .5MOA. As I got within 20 thou of lands groups got very tight. I think the H4350 load data in the doc above is pretty conservative and easily worked up to 43.7g at 2.825”. Nodes were at 42.5 and 43.2. Sierra’s guidance on load data suggest a max around 43.5* (see 130 Tmk)

Overall consistency of weights and measurements is excellent, far exceeding my needs as a deer hunter. I’m very happy to have these tipped gamekings and have six whitetail tags to test them out on this season. Maybe I’ll get two each of lung, high shoulder, and neck shots.

I’ll be working up some .308 soon for the upcoming deer season

Posting on this thread is resurrecting the dead but the topic is right. We shall see!

Has anyone seen load data for the .277-175 TGK? I actually called Sierra and even though the conversation was congenial he had nothing to offer. I did learn more of what I already knew about load development and the tremendous work load the demand for products has placed upon the industry. He said they were ecstatic to get them into shooters hands and all he could offer is they are working on load data.

Soooooo... The best I can come up with is data for Berger 170s and progress slowly since the TGKs seem to have much more bearing success surface. Feedback? Suggestions? Place to look?

Start with Bergers starting load and work up. Make sure your barrel has enough twist.

I've been playing with the 100 grainers in my 243 8 twist. Not to shabby so far. The price doesn't hurt either ($28.95 per box). Using N-165 and Tula primers.
