I thought this would be a lot more interesting than just writing "HEAVY". We'll see if this 100# box of linotype arrives at the new place.

Yeah, if you plug in a decent case vol and length, it's been good within 50fps.

Lee, Lyman, and RCBS cast bullets in there too (including some that are out of production).

This run shows loads with the same barrel times. Sorry for the crappy formatting. They are listed fastest to slowest by MV for a 1.129 ms barrel time. Varget is certainly going to work but it...

I had to fudge your case vol some (in the bigger direction) to get stuff to line up with your 45gr velocities. I suspect your fired cases may be quite a bit bigger than the brand new ones--or it may...

Where's the pics?

I've got a 257 Rob AI. It's done superbly with the 257312GC (frequently 5 shot groups inside an inch at 100yds). I also have a 257325 clone from NOE (260325 I think it's around 117gr) and that's...

With pretty soft bullets (I use 1:1 ww to soft lead and the 257420 bullet), I do well with Win231/unique powders and no gas check. I go with a harder alloy when pushing harder with 4227, 4198, etc.

Nice. That's the kinda thing I was looking for. Did a search but nothing popped in the first 4 or so pages.

Thanks

The mold rest under my Lee 20# pot does not work well with my new Mihec 455 220gr HB mold. Hitting the hole requires a very precise geometry and the pins are gettin in the way. Anybody got a good...

I cast about a hundred of these in poor light as soon as dinner was done last night. I have a S&W 2nd Model HE with enormous cylinders and bore (4585) so I went with the 457 flavor. With the 3:1...

Mike, thanks for the response

The last round I went with it was in March with temps between 35 and 40F (I think that's around 7C). 5 shots and then a long slow trudge through the knee deep snow...

Woohoo!!

I don't think you're going to stay supersonic at 1000yds, at least not with that 308 combo. The 168Sierra won't do it at 2550; the SST looks like it poops out at 900yds. If they drop below about...

I'm interested. What alloy and lube are you using?

I've got an old Savage in 257 Rob Ackley Improved that I've been tinkering with. I can get about 10 shots sub-moa but then it opens up to...

I know I'm very late to the game here, but providing info for prosperity.

My 9mm powder funnel mics at .353. My 38/357 funnel mics at .355

To get the 357 funnel into action for 9mm, I ground...

Yay! This has turned into a spendy month for me 455-wise.

That's excellent info! Thanks! I've got my PC bullets in the oven at 455-460F. I'll drop them in water after a half hour or so and see how they shoot. My Lyman Cast Bullet HB says HT is done at...

Thanks for the ideas. Last thing I shot with the rifle was a doe back in December. I know I at least patched the bore after that. Maybe not though.

Bullets were all sized in the same manner.

I tumble PC'd some bullets and shot them today using a load that has delivered great accuracy with a non-PC bullet (frequently well under 1MOA w/ fliers occasionally).

257 Roberts AI, 257312 GC,...

I have a 257312 mold. It shoots amazing groups from a 257 Roberts. But through a Win92 25-20, I have to push them at Max just to keep them from keyholing. The 257420 bullet shoots beautifully...

1. 3 fouling shots
2. PC: HF red, dump and bake on a wire rack, 13min @400F.
3. Bullet: Ideal 257312, 2:1 COWW to SOWW. No culling. Sized .257 after PC
4. Powder/vel: alliant 2400; 1960fps

Rem 722 257 Roberts

I shot moly'd bullets (Neco) for I think 2 or 3 seasons in my match mule. Shot it twice a month and the bore was mopped out usually on the same day. I ended up with pitting in last 6" of the bore. ...

I've got a Winchester 92 in 25-20. It really likes the 257420 bullet. Don't bother with a GC for 3'ish gr loads of stuff like unique, Win231, etc. When I shoot 2400, 4198, 4759, etc, I use the GC....

Been doing some work recently with my 257 Roberts Ackley and have been very pleased with every bullet I've tried in it. Pretty much everything drops inside an inch without much fuss. Shot some...
