That one has also been on my radar for tests in the grendel, and in the 6.5x30/30 Ackley. Hope to see some
bullet expansion tests on pork-sized targets.
No, but thanks for the heads up. I’ll have a Grendel eventually, been saying that for a year. I ordered a 20” 6.5 CM today instead for a handy little Encore “carbine” project.
After seeing your post, I read about these 120’s on Sierra’s website, then shopped around for them. Everywhere seems to be out of stock.
I am going to try them at some point in my XP-100 .260 Remington. I also plan to try the 120 grain Pro Hunter flat base.
It's better to shoot for the moon and hit the fencepost than to shoot for the fencepost and hit the ground!
Well, I did some load work with these tipped Sierras today. I started with the BRM. I got acceptable accuracy but decided not to waste more time or bullets since it previously didn't do its best with sharp-heeled boattailed bullets. Remembering I had an open bag of new Starline 30-30 brass on my loading desk, I decided to give the 6.5 Bullberry a whirl.
I lubed a batch of cases, ran them into a Pacific Durachrome 30-30 neck die to remove imperfections and true the necks and then ran them into a full-length Redding 6.5 BB die with the decapping assembly removed. Next, I ran them into a neck-size die. Doing them this way minimizes the creation of the false shoulder or doughnut. I then trimmed, chamferered and deburred.
I started and ended with SW Precision powder. The accuracy was exceptional. The first three still showed a good bit of sooting on the neck, indicating the load was rather mild and not developing enough pressure to fully seal. I bumped it up a half-grain and then another 0.3 and was rewarded with the same type of gilt-edged accuracy at each level.
Now I just need some cooperative swine so I can check terminal performance...
Below are three of the loads in newly-formed Starline brass. Please pardon the low-rez (and canted!) phone picture. I don't get along too well with the phone camera ha ha...
looking forward to seeing your report on these. I have some of the 130's that I bought a couple of years ago but was unaware of the 120's. Probably because I stopped looking for Sierra's over a year ago because they were never in stock except for some of the Pro-Hunter flat based bullets.
