SIERRA 107gr. HPBT load data, accuracy issues?

[GREYBUFF]

Bought a box of these and was looking at some data provided by a major supplier and there was a review that these don't work well in a GRENDEL.
Any one have any experience with these? Thx.......paul

I'm still doing the load development (slowly, ugh) but they shoot as well as anything I've tried so far.

I tried them in my 12.5" 264 LBC pistol. I had single digit SDs across as well as decent groups across the board doing load workup with Benchmark. I might be there at max at 2440 with no pressure signs but my last groups were a bit disappointing. I finished my box and will probably wait for warmer weather so I can get a bit more comfy trying to shoot a pistol with "Precision". I may just end up going with 123 Scenars instead since they are the same price and I buy them buy the 1k.

Add: I also tried them with XBR. Had good accuracy and really low SDs in the low 2300s which doesn't cut it (I should be able to do low 2300s with 123s in a BHW). Started getting some pretty serious ejector marks 0.7 grain off max and called it quits. As much as I love XBR with 77s in 223, I honestly don't know how anyone else uses it with Grendel. This was the 3rd barrel where I couldn't get near Hodgdon max.

I've only ever shot the 107 SMK in my Moscow Match development (taking Wolf steel case, pulling the stock bullet and replacing it with another). Sub minute out of my AA 16".

My guess is that like every other bullet/barrel combo some barrels gonna like 'em, some not.

BFT:

It seems like over the years more guys have commented on the 107 Sierra being either outstanding or absolutely horrible than any other bullet I can recall. I never got it to shoot well from any of my Grendels but other guys had absolutely no problem. Never was able to figure it out.

The 107SMK shoots the tightest groups out of all the bullets I have tried from a Lilja 18".
