Sierra 175 tipped match kings load data

[Darkside-Six]

I just picked up a box of these to try out. I usually shoot the regular 175 match kings. Anyone have good results with these? did your charge weight change between the SMK and TMK at all?

Thanks in advance.

We've had a few people recently try them out. Both had an optimal charge weight of 44.7 grains of Varget. They are jumping .020" and shoot exceptionally well.

I was shooting both the SMK and TMK Lapua brass 43.2 Varget for both. They both shot ok but I changed to the 178 ELD Hornady and got better groups at 100yards and shot better out to a1000 yards.
Shooting a 1-12 twist 26 in barrel.

175 TMK's out of a Snowy Mountain 308
2700 fps and tiny groups with 42.5 grains of IMR 4064
CCI 200
Federal Cases
1350' above sea level

I don't have any SMK load data. But I know TMK's don't like to jump as much as SMK's will

Im running them in my LaRue 18 inch, 44.6 gr Varget, FGMM Lr primer, Lapua brass, 175 TMK at 2.840 COAL is getting me 2600 fps with a SD of around 5 across 10 rounds. Most consistent round ive shot at 1100 yards from a semi auto, prior to this I had Hornady 178 Amax, and also tried the Berger Jugg 185s. The groups opened up past 44.6 and I wasn't picking up much velocity, pressure signs started at 44.9 gr with popped primers, but its a semi auto, so likely youre going to be able to stretch that OAL out and get more consistency with a bolt gun.

I just shot a 1000 ya match yesterday and had 3 tmk blow up out of 75 shots. My load was 44.3 of Varget . Has anyone else had these bullets come apart on them?

I shot some out of a 300WM @3000fps. No problems

Now how do you know they blow up

Now how do you know they blow up

All my shots were good and the guys in the pits said they heard a weird sound on the shots in question
