Has anyone toyed with this combination? I bought a couple of boxes of these bullets a while back with the idea of seeing what kind of accuracy I could wring out of my old Model 70. I haven't had the opportunity to try anything yet so thought I'd ask here and see what ya'll have tried.
Thanks!
Thanks!

I use H4831SC and Winchester LRP primer. O'Connor used the original H4831 long grain powder, he used magnum primers to be sure he got that old stick powder lit. I have 2 pre 64 M70s, a rifle and a featherweight, I have a post 64 M70 270 built in 1972, supposedly the worst of the post 64 vintage. That 1972 vintage 270 shoots better than either of the pre 64s.

My dad killed a bunch of elk with his pre 64 featherweight 270. He read everything O'Connor wrote and swore by the 270. I've killed white tail, mule dear, local black tail, Caribou and a couple of elk with a 270. I'm a believer.

On their website Sierra says the 135 grain bullet is not recommended for hunting so I guess for handloads I'll stick with their 140 grain sbt's for that. The 140's give great accuracy from my rifle with a moderate load of 44.5 grains of 4064. For some reason it doesn't do as well with the 4831SC that so many favor/ Doesn't appear that many folks have played with the 135's so I guess I'll have to start from scratch and see where things go.
Here's an odd thing I found out about them....If you have a rifle with
a bad crown on the muzzle, the SMK seemed to be the best to tighten back group sizes. Must be the big boat tail they have.
I shoot the Matrix 165 and 175 VLDs out of my .270 AI. I have pushed the 175 near 3100 FPS out of my 30" Lilja 1:8" 3-groove but my current accuracy load is 2993 FPS.
