22-250 cast load

[buggybuilder]

Has anyone on this forum used a RCBS 52gr. gas-check mould?
If so, can you tell me what load you used and what kind of groups you shot?
Thanks

I must have a rare mould, in fact it apppears I have the only one they made!!
Thanks for all your help.

Maybe not the only mold but maybe the only one to use it in a 22/250.
I have the mold but have modified it to a 50gn PB.
I have recently been shooting a 22/250 I put together using a Turk action and a Rem take off barrel that was a 222 mag. The conversion worked well and I am pleased with it.
Just because I had a pound of E-3 that needed burned up and some odds and ends of 22 cal boolits I thought to put them together. Wonder of wonders it works great with 8 gn and about any boolit that will work in a 1/14" twist.
My favorite is now the NOE copy of the RCBS boolit with 8gn E-3. Its gives very consistant velocity at about 2000 fps.
I dont know if E-3 is even available anymore. Seems it came and went without so much as a pop let alone a bang.
Anyway if given a chance I will buy more just for this purpose. If you have some try it.
This load outclases the 22 mag RF by a good margin and is far cheaper to shoot.
With a 100 yard zero it is still flat enough for PDs with a center hold out to 150 yards, and holding just a wee bit over its good to 200 yards. The flat nose boolit still has an audible WHAK when it hits at 200 too.

15 grains Reloder 7 and the RCBS bullet will get in the 2100 fps vicinity and groups very well in my rifle, on the order of 1/2" or less at fifty yards.

Plenty good as a small varmint and small game shooter.

if it is the 55 FN then yes and also the 55 SP.In my 1-12 Savage barrels it shoots about 1"-1.5" at 100 yards.I use 13.5 5744 @1900 fps or so.
the 22 Varminter is my favorite 22 caliber cast cartridge over the Hornet and 223.

I have the RCBS 55gr FP

and now I have a Handi in 223, the Featherlight, or something like that... very small, light barrel.

I'd be happy with 2" at 100m for a coyote (Pronounced "Ki-ut"// i = eye sound) gun for around my acreage.

is there any advantage to the 22/250 over the 223?

[altheating]

Buggybuilder, I use the NOE 22-055 FN in my 22-250. I tried that RCBS boolit and it didn't shoot for beans. I think my mold was bad. It did not do well in my 223's or the 222's either. With 17 Gr of 4759, GC's and Speedgreen Lube the Ruger 77 it is a tack driver. I now use that NOE pill in two AR's, both 222's and two 223's plus the 22-250. Pigeons and crows out to 150-160 yards so far.

I have with 8.0 grains of Unique in my Rem 700. Ten days ago I was hitting a 4" wide plate at 250~300 yards with it under windy conditions. On a calm day I can hit a business card sized target at that range with it 50%+ of the time. I use std Lg Pistol primers. I have found that increasing the powder chg makes it much less accurate. The drop from 250 to 300 yards is about 30".

I think maybe yes. That would be equal velocity at lower pressure.
Of course there is also a disadvantage caused by the larger case and low load dencities.

The real advantage over most current .223s is the 22 -250 generally has a 14" twist in leiu of the 7 - 9" twist commonlt found in .223s these days.

Of course there is also a disadvantage caused by the larger case and low load dencities.

I've not found that to be a disadvantage if a filler is used with medium burning powders. With slower burning powders the filler is not needed. I use the 225462 in my Rem M700 with 14" twist. I am able to push 2400 fpsand get consistent 1 - 1.5 moa. I am able to bush 2600 fps with less than 2 moa concistent accuracy. 'm looking forward to testing the 22 NATO cast bullet from Mihec.

[runfiverun]

not too sure about any advantage.
the same rcbs 055-sp boolit works equally well in my 223/22-250/223
they all use the same load as well with about equal accuracy.
the faster powders do vary in how they perform in the different cases.
the slower ones are more equal.
for instance 13 grs of 2400 in the 223 is equal to 16.5 grs in the 250/swift accuracy wise.
but 22.5 grs of 4895 works to the same accuracy level in all three.
dunno how but that's how it's working so far for me.
eventually i'll move down in burn rate in them.
but i'm good with the accuracy/velocity level for now.

The Savage/Stevens 1-12" 22-250 have been very forgiving for me with 22 bullets from the 225438(no gc @ 1300) to to my original 62g Eagan @2100-2200.I haven't found the larger capacity to be disadvantage. (down to sub 3/4" groups anyhow) I use 4759-4227 and 2400 mostly with 13-15g charges.My smallest group with cast bullets I ever shot was my Savage 22-250 BVSS-S with 14.5 of 5744 and the 62 Eagan. it was a 5 shot group at 100 yards a bit under .200.The three other 5 shot groups in the string were all under 3/4".I never did it again.MyStevens 200 22-250 averaged 1.4 MOA for something like 100 consecutive 5 shot groups tabulated at 100 and 200 yards with the same loads..

Both my Rem 700's have a 1 in 12" twist (.223 Rem/.22-250 Rem). The .22-250 is more accurate with cast bullets....however the .22-250 is a Varmintmaster model (heavy target barrel). The .223 is quite good out to about 200 yards with cast loads. The "key" to accurate loads in the .22 Caliber is to seat the bullets long so they just touch the leade. I typically load single shot style.

Remington hasbeen switching the twists of several calibersthe last few years. .223, 22-250 and .308W in particular. A 14" twist was standard in the 22-250 for many, many years. Probably went to a 12" twist to use the "heavier" bullets or to simplify production for better proffit.

If you want to push cast above 2200 fps with varmint accuracy the 14" twist and case capacity for slower powders of the older 22-250s is the way to go. 12" twists are obviously working quite well up through the velocity you gus use them at. Same with my own 12" twist .223s.

"seat the bullets long so they just touch the leade"

I agree-I have an Eagan taper die in 22 i use to get the bullets into the throat to the first band at least.I had LBT make me a tapered 60 SP bullet that is wonderful.

I used the RCBS 55 SP-GC bullet but did not pay attention to the loading length--I detest not seating the bullet to cover the grease groove. I found that I have to seat it out, exposing the entire grease groove, in order to get good accuarcy with it. In the .23 Rem 700, with that same bullet, seating it enough just to the edge of the GC wasn't enough---it has a long throat. Only going to the Lyman 58 RN-GC (225462 I believe) solved the problem.

[Larry Gibson]

Yup, certainly concur with that Wally. The Lyman Lovrin design 225642 has thus far been my most accurate bullet in 22 CFs with twists of 14" or faster, especially if pushing above 2000 fps in 12 & 14" twist barrels.

However I sure like how that RCBS 55-SP-GC looks...my Lyman mold is a SC ..can you imagine how tedious it is to cast 1,000 of 'em?

[Larry Gibson]

Well, mine is only a double cavity so I'm only twice as fast.........[smilie=l:

I do have the DC RCBS .22 Cal mold...that bullet works very well in the .22-250 for me. 8.0 Grains of Unique gives me 1,875 FPS. The BC is so poor that at 200~300 yards one gains little ballistically to shoot at a much higher velocity. I used to use 10.0 grains of Unique (2,200 FPS)...it was not all that accurate. At 50 yards I'd get 3" groups. One day I tried 8.0 grains---groups shrunk to 1/2"...lesson learned. BTW I use Freechex GC's and found they are just as good as Factory made.

That's about where I ended up with the Lyman 225415 also. The FP with the longer nose are the probable limiting features of both bullets I think. I never did get much usable accuracy over 2000 fps with that bullet in any cartridge regardless of the twist.

Good to know that we have the same results. That one blessing about this forum---to share experiences with fellow shooters.

It is exhilerating to shoot the .22-250 with cast and hit index card sized targets at 250~300 yards. The fact that the cast bulelst are traveling so slow really makes no difference. Cannot wait to get out to shoot mine again.
