Do you use bushing dies and expander Mandrels? Together with frequent annealing that’s the best way I know to get consistent neck interference/tension.
I’m hoping it will hold stability out to 500-600 maximum.
Im thinking 9tw would be safe.
Safer anyhow.
I’ve got faster barrels for big Berger/monos. And more capacity to push them with!
The bullet is absolutely capable, typical Nosler results in my experience.
Those groups are from a 25 Sherman...
Anybody using a 1-10 twist with the ,257 115gr BT?
Ive got someone trying to talk me into that barrel but I think 1-8 or 9 covers my tail.
Im expecting 3200fps after FF/break in.
Get an external trigger for the Labradar, and a steady mount with 3 points of contact on the bottom, preferably hard rubber “feet”.
in addition an external power source.
You will enjoy it more with consistent shot readings and a longer lasting power supply.
I ran out of patience and swapped to the 153.5 Berger, it’s the bullet I had in mind when I built the gun.
I’ve got a good supply. Still FF’ing brass but I wanted to start playing with seating depth on it anyhow.
after sighting in at 100, these are my first 2 groups at 300yds. Measly 2780 fps...
Great info! I assume Bartlein hand laps. I’ve put about 60 through It now, might have to let it get a layer.
It WONT be difficult.
it gets clean quickly with Boretech.
Is the jacket material used on ABLR softer than what is used on BT/AB?
I know it’s a new barrel but I’m still getting a good bit of copper, now. And I’m cleaning every 10 after starting out at 1-3 shot intervals. new territory for me with this bullet, so I’m full of questions here. Thank you...
Got it repeating today from 1/2-3/4” at 100. 50 shots fired on new barrel now.
Moving to 300 this week hopefully, kept powder and primer constant and just went deeper and watched it tighten up.👍
Taking it easy on the new brass, 300 fps under max at least.
For a little while…
I do appreciate the first hand knowledge you share. After I get this Bartlein loose I’m going to give them a serious go.
pulled my LE Wilson seater out today, and realized it’s not the Mic version.
But the lathe is only a few miles away to get that fixed, thankfully, when the new one arrives.
I...
I’ve always wanted to try these but…seems some people can never get in a comfortable groove with them. And yet others say they are simple to tune!
im looking for general recs to apply here, concerning seating depth. And anything else pertinent.
looking at the 6.5 142 gr specifically, and I’m...
I’m thinking you have the possibility of shooting animals lot farther than 100yds with that cartridge.
stretch it out to 300 or more on paper and see what happens.
It’s not exactly terrible there, if it gets no worse at distance I’d be leary of making much of a change!
Good luck with it.
