What powder are you trying?
Have RE17
Try mag primers with different powders behind the LRAB.
You might get them to shoot.

Alreadt using them. Always have.
Very nice rig.
Good to know the FF loads shoot well. Is the speed on the FF loads still usable for deer etc?
Bloody batteries were flat in the Chrony. Seriously considering a Magneto V3.
0.92" Seekins rings?
Not sure...were laying around. Individually engraved numbering...similar to vortex.
Magneto V3 purchased...might have to wait until Xmas to speed test :(
Wish I had realised you were so close when I lived in waipara. In timaru now though. Inspiring to hurry up and build mine now
Tikka do you come from Amberley? think I recognise the Defender in you pics, seen it at Amberley Z station the other day?
No. North Loburn.

Nice looking range setup. Is that on your patch in North Loburn? My brother lived on Carters Road for a while with a similar pine outlook.
In-law's farm next door.

142gn LRABs 2909fps 44gns RE19. Going to try hotter and should easily make 2950fps.

140gn Amax 2987fps with 43gn RE17.
Primer fine but noticed bolt lift tight...I didn't change the seating die from the LRABs...but primer AOK?
Definitely promising.

Bloody windy day too. Magneto V3 worked well.

Nice velocities! What length barrel are you running?
As R93 said, you won't see normal pressure signs like a standard case shows. My 257 AI would indicate high pressure with a stiff bolt handle and the primer still looked ok.
Good speed & group looks decent too
24" barrel. What I couldn't figure is 44gn with the LRABs was fine but 43gn with the Amax had stiff bolt lift. I think it must be because the LRABs were seated with 20 thou jump but the AMax's are into the lands as I didn't change the seating depth from the LRABS.
What shot is the "one" out of those 3. Just wondering about the 1 and 2 patterns
The bottom right group is from a 7mm08. The LRABS ES was in the 20s, the Amax's were 7. I found the LRABs vary in weight a fair bit so will weight sort next lot.
Where did you get your magneto? Bloody awesome bits of kit
I got it from Wilson's for $899. They were great to deal with.
Thanks. None im stock atm.
Will this wind ever go away...probably can't tell from photo but blowing so hard the MS is shaking on barrel. 1" 100 yard group with 44.5gn RE17 2959fps av and SD 15.1. Still 45.0gn and 45.5gn to try.http://images.tapatalk-cdn.com/16/01...3016d73ae4.jpg

Looking good.
I use a bit more powder to achieve similar velocities but I coat my projectiles.

Yep sitting here waiting for the wind to die (not likely) and v.happy to have 2950fps from 24" barrel with 142gn. Will try others but might then sit on that and play with seating depth...these are 0.01 jump so quite close. 100yard zero and nowhere near 1 rev on the NF F1 Moar for 1000y.
A photo of where the MS sits relative to the muzzle. Have found it likes to have the muzzle a fair way forward.

45.5gn RE17 3007fps av and 10.7SD. Group opened a little but was most likely me rushing. No hard bolt lift, no difference from mild load. Thinking I will play with seating depth with 45.5gn...?
Sent from my SM-G925I using Tapatalk
That's what I would be doing now too. Speed is there so adjust seating depth until you find accuracy your happy with.
The last few load developments that I have done, I have found where I wanted to be speed wise with acceptable pressure, then just played with seating depth to get the accuracy I wanted.
Has worked very well!
Also on mine it shoots a lot better once I take the magneto off
Sent from my SM-G900I using Tapatalk
Possibly less affected as stiffer...will find out when I shoot with it off as now playing with depth for accuracy so don't need it attached. 3000fps is more than hoped for so need to chase more pressure.
Having a play with this now...7mmSaum. Not so pleasant shoot with radial break. 66.5gn 2217 3020fps and 7.1SD.http://images.tapatalk-cdn.com/16/01...3b3d93d862.jpg

162 amaxs?
Yes. Got some 140ABs over 67.5gn to try too.
