Sierra 105gr Blitzking data - jasper2408 - 02-27-2023
For anyone that has the new Sierra version 6 manual is the Sierra 105gr Blitzking bullet load data in that manual?
TIA

It's not in the paid version of their reloading app for whatever that's worth. I'd assume that the app would usually be more current than the books but I don't know that for a fact.

Email Sierra and ask for data.

I downloaded the Android version but it is version 5 and didn't have it. The Android app that I downloaded hasn't been updated since 2019 so I canceled the subscription. On their Facebook page they have a link to version 6 for iphone but the page just sets there and does nothing once you click the link. If Sierra would put out an up-to-date mobile version I would buy it for sure as I use the Hornady mobile app all of the time.

Just emailed Sierra. I will post what they say when I get a response back.
I have worked up some max loads for several powders that I have using GRT and QL and will use them if I can't get any data. I had to measure the bullet and import it into both programs.
Thanks everyone.

use the 107 data, the 105 will be a few fps faster. work up as always.

Thanks for the tip grayfox.

107gr SMk and 107gr TMK have the same data in Sierras manual and online resources.
No reason to think 105gr Blitzking will have different data. I suspect they will lump it in with those in future editions/updates.
Xterminator at 29.8gr max
Power Pro Varmint (30.9gr max)
TAC (30.5gr max)
Gave the best velocities.

i just picked up a box of these bullets the other day at graffs...they do look good
i put a couple loads together using the 107 data for ar-comp...used 27.5 and 28gr at a 2.250oal.....think it was 1 gr under max...used the data from the new lyman book....sieara did the same thing with their game changer bullet..they told me for that to use close data ..like for the 64gr bullet use the 65 data and the 130 to use i forget now but it was a close weight ...so thats what i did here...start low and work up
i will say that the loads i put together are pretty full...so it is compressed...i do have some other powders i want to try with this bullet...it should make a good yote killer i think...sure looks good
now if the wind and rain will take a little break so i can get back at the testing....for the rifle and load work

Thanks for that info ocharry, AR COMP info is always welcome.

Based on testing with 123gr eldm today and just looking at these things... I'm going to start with 31gr of staball match and stop at 33 for the first run. Expecting 2780-2800 near the end of the test if I'm doing my math right and predictibality pans out.

What barrel length?
Sierras data shows 107gr maxing out at 2750fps from a 24 with Xterminator and PPV.
Did you try Staball Match under something else? If so, sorry I missed it. Looking forward to that.
ETA: Just saw it. Disregard.

Latest QL did not include this bullet, so I entered it based on measurements and threw it in QuickTarget. Indeed, a very interesting round.

it rained all day here yesterday so i spent some time in the load room putting some of these 105's together with different powders to try in my rifle...did some 95gr hornady bullets too...kinda christmas colors...red tips and green tips...lol
man this weather is so crazy...cold and windy...rainy as heck...just windy...lol... i got things to do
rifle function tests....load work up...but now i gots me lots of loads to test...
crappy day spent being productive in the load room...

Gonna go with SW Tactical and SW Match loads first. I have a bunch of 123gr HPBT already loaded using Match powder to fire-form my new Starline cases first then will start with load workups. I measured all of my magazines inside and they all are 2.330" so I can go longer COAL if I want, which I probably will eventually.
Gonna start with 29.12gr max with Tactical and 31.26gr max with Match. Gonna go 10% down from those maxs to start load developement.
QL shows velocities at max load of 2684fps with Tactical and 2781fps with Match. I imagine those velocities might be a a little high for a 20" but we will see. In GRT the load for Tactical was 28.62gr(.5gr less than QL) and for Match was 30.90gr(.36gr less than QL).
Load specs:
20" barrel
2.260" COAL
35.6gr case capacity-Starline brass
1.510" case length
70 deg temps
Disclaimer:
Do not use any loads from QuickLoad or Gordons Reloading Tool software that I post as they may be dangerous. The loads I am posting are worked up with QL or GRT for my bolt guns only and have not been tested by me yet or any pressure testing authority.

I'm about to do a run up with staball match. Mind if I post results here?

Not at all. Any data for this bullet is welcome. Anxious to see your results with Staball Match.
Sierra 105gr Blitzking data - Zeneffect - 03-05-2023
Loading up now, if using hornady bullet seating die, it seems the stem #397106 fits better than the one it comes with. This is the one you would use for the 135gr a-tip
Sierra 105gr Blitzking data - Zeneffect - 03-05-2023
Well... seems 32.5gr of staball match might be the limit. Pretty hard to get much more in the case and not observe coal growth due to compression. Going to blast over magnetospeed in an hour or so. 31.6-32.5gr in .3 steps (4x loads of 5 rounds each)
Sierra 105gr Blitzking data - Zeneffect - 03-06-2023
Well pulling results now. The tldr is the combination works, but there most certainly are better powders. 32.5gr gave me 2739fps average so my predictions seem to be spot on. External ballistics simulators show that I really want this as close to 2900fps or faster for my needs. Realistically I will be happy around 2850 out of a 22"
