I messaged Jeremy months ago about doing a prefit with a reamer from Blackjack but he wasn't sure about it working with his CNC lathe. They are so backed up with work that I didn't follow up anymore.

Very surprising though. I used 140gr BTHP that hornady offers and had great results this season. I took 2 bucks and 2 javalinas. All but the biggest buck were DRT. The big buck, that did run, left huge massive pools of blood in the brush.
At 155 yards they came apart. Massive damage but not what i’m looking for. I shot three between 365 and 375. One behind the shoulder. It ran about 100 yards and expired. Very little exit wound. Maybe a quarter. The bullet didnt expand. The other two were shot just in front of the front shoulder (my favorite spot). I had to cut both their throats. This has never happened before at any distance and with any other cartridge. My .30 carbine at 100 yards will drop them in their tracks. The 147 eldm held together up close and expanded nicely at distance just as any good cup and core bullet would.
Ive seen just the opposite, a 147 (from a 260ai) than didnt open at all on an elk shoulder (at 600 yds tho). And we used the Hornady 140 BTHP (260rem) to take a big bull elk a couple months ago, they worked as expected.
Interesting feedback on the 147. Have seen some guys with good success with it, but I shot a big axis deer in the (thick) neck with a 130 ELDM at 200 yds and it completely penciled through. Literally 0 expansion. Deer dropped dead like most neck shots, but I was not impressed.
Did some initial load development for the 25 Creed. Looking good but I’m going to get a non-bushing sizer made.

Could you let me know where and when you are getting it made? I would be interested in one of those as well.
Not to be personal, but any idea about how much one of those would run?
This is good to know. Been waiting on a Nucleus 25 cm barrel
I put an order in with Whidden for a custom die and attached the reamer print with some additional notes on my neck measurements.
$165-185? Can’t remember right now but you can check his site.

Depends on what you mean by hard to beat. Im sure people were saying the same thing about 22-250’s and .243’s, then along came the Creedmoor.
Just so everyone is aware been waiting on a reamer from blackjack for a few weeks now. They seem to be back logged a bit.
Late last year they were told by Manson that they would be in by January and the most recent estimate was "after SHOT," with JGS following a couple weeks behind. I'm also waiting for one as well.
Yes, BJB is at the mercy of the manufacture at this point. We have passed on every update we have gotten and expect them to be here soon. SHOT has delayed delivery by a couple weeks and currently a major storm has hit MI and not helping matters.
I’ve never been accused of being a patient man, and I understand they are at the mercy of the manufacturer. Looking forward to receiving it.
As others have said, Logan and Miles are standup guys and will do right by you when given the chance.
What size bushing are you running?
Coldboremiracle has this info in his writeup. Go with .281 or .282
That sounds like something I said.
1.415
I’ve got a 25-06 that shoots incredible, but I’m limited because the guy that built the rifle put a 12 twist on it for whatever reason. I already have all the brass, dies etc, so I’m thinking of redoing it with one of these fast twist barrels and putting some bottom metal on it. Right now a 100 gr NBT and a stout load of R22 will get me 3450, but that’s the biggest bullet that I can shoot. Would be interesting to see what it would do with these bullets.
My new rig will have a steady diet of 131g bullets. I Ordered 2k of them. For any skeptics - just plug this bullet into your ballistic calculator and try to control the mouth drop. Then adjust the B.C from .330 to the real world reports of .350. It’s legit.

Can’t believe I didn’t put that in there?
Of corse! Both of those are absolute top notch components! Prime em with FGMM Small Rifle Primers and fill em with H4350, had an SD of 9 while fire forming brass. Need to do a final chrono because I’m sure my barrel has sped up a bit since I checked it before the match!
Thank you sir!
Necking up 6mm Creed will push everything to the outside of the case and won't cause internal donuts. I suggest using a 21st Century expander mandrel to neck up 6mm brass to .257.
I’ve been told necking up can shorten necks and was advised to neck down. This was after I had already necked up 6 Creed Peterson brass. My observations were my concentricity remained perfect but the Peterson necks were too thick for my .289 reamer and I was getting weird random pressure signs. I switched to 6.5 Creed Lapua and necked down. Pressure signs went away but concentricity is pretty bad after first pass in die. Pressure problems went away though. I don’t like how I can’t size down to neck shoulder junction with bushing dies and so I’m waiting on a sizer from Whidden. I’ll have to do next reloads still with the bushing die so hopefully concentricity improves since it is floating and sizing down less.
I haven't necked up 6 Creedmoor to 25 Creedmoor, but I have necked 243 up to 260 without issue. If it shortened the necks at all it was too little to matter. This was with Lapua brass.
I neck up Winchester 243 cases for my 260.
I have 30+ shots in some of them.
I usually size up to .257 then .264 in a 21st century expander die.
You can get donuts necking up thick shouldered brass but they are easily dealt with.
I like seeing the quarter bore get some love.
Me too, and I have never had any problems necking 6.5 brass to 25
Lilja told me he does not offer a .25 caliber 7,5 twist MTU
well im sticking with the 250 savage, mcgowan makes savage prefit in 1:8 twist barrels.
i have easily got 42grs of reloader 17 under berger 115 gr hunter/match bullets. started seeing flattened primers.
bumped back to 40grs and much better and an avg 3065 fps but the 1:10 twist barrel doesnt give good accuracy with it.
i think i can get the 131's to 2850fps. so ill post what happens with the tighter twist barrel.

Has anybody worked up a load for the 25 with a powder other than H4350? If so, what were your results?
42.6grs RL 16 with the 131 Blackjack. I couldn’t get decent speed with H4350. Rock Creek barrels always seem slow though.
That's the option I was considering.... What kind of speed are you getting?
2945 FPS from 24” Rock Creek. 7.25 twist I believe. Forgot to mention in last post I’m using Alpha brass.
Thank you, that's the node I want to be in. What do the groups look like?
For what it's worth, in my rifle at least (26" barrel), H4350 is about 25 fps faster than R16 grain for grain. Now R16 can take velocity higher to say 3050 without as much pressure, but it is highly compressed in Lapua brass.
