Fancy new mold...

[44Blam]

I recently acquired a 350 legend upper...
I inspected it when I got it and then ordered a mold that *should* work (according to my calculations) from Accurate...

It is the Accurate 36-180LG. I had the lube grove removed since I powder coat all my boolits.

Bear Creek Arsenal had a good sale on complete uppers ($269.99, $293.10 total) a couple weeks back, but the prices are back up...

Let me know how that shoots. I came up with that bullet going off of the prints that were out back last year. I never did order one as I wanted a HP mold. I ended up with a mp360-200 hp RCBS clone.

Will do - it'll be about a month or so. I haven't cast any yet. Now that it's here I do have the itch to cast a pile of boolits with it, but I think it's gonna be a few days before I get around tuit.

I do have another design that is an Accurate 35-125YG. I shoot these in 357 sig, but it should work in the 350 legend as well. I have a bunch of those just ready to load.

I was looking at load data for that 125 grainer and it looks like you can push 2500 fps. With the 1:16 twist, 2500fps is 112500 rpm -- well within hard lead limits... And the 180 grainer (probably more like 190 or so cast) should be going in the 2000-2200 fps range.

I am excited to play with these.

[cwlongshot]

I have been liking the 190 ranch Dog bullet!! I have a copy without the TL grooves and it dosent shoot as well. Its also got a slightly thicker nose. My MAXI LOVES IT, the legend dont. Go figure!

My plinker is a Saeco 396 its a 180 tc looks allot like the RCBS Silhouette bullet.

I shot this with mine yesterday. It has a BCA barrel. On Target software says it is the following.
The max spread (CTC) is 1.077" MOA is 1.029"
Group height is 1.058"
Group width is 0.737"

Looks good TB!!

I finally found my extra brass last night!!! I have been searchin for over a month!!! Now I can start some More ladders! Pretty much decided on a AR bbl in 350 next. I just need to find the right profile. I think I want 18" but want light (er) contour.

This is 16" with a 15" hand guard. 45 irons/2x8 scope. Here in Komiefornia, you can't have a flash hider, but a muzzle brake is fine - so muzzle brake it is.

Yep - I'm in the process of PC'ing my first batch of these. I got the mold without a lube grove, so they will be a bit heavier.

I've got some fired brass, so I can just seat a boolit way too far out and chamber it. Then back out about 0.01" or so... Hopefully it is similar seating to what you have done.

I am very excited about this caliber. I cannot wait to see what a bore-riding 180 grainer will do.

[44Blam]

Got around to loading these guys...
They are powder coated, gas check'd and tossed in BLL. The boolits were air dropped but water dropped out of the oven after PCing. They're about 15-16 BHN. Pretty hard.

I decided to start out my testing with the hodgdon reloading W296 suggestion, but I believe their bullet is seated a bit further in the case since their max listed load still has a little room in my case - I might do some testing with maybe +1 more grain or maybe 1.5 or so just to fill up the case.

I did identical loads of W296 and AA 11FS - the powders are nearly identical with the exception of AA 11FS is a little darker and EVER so slightly bulkier.

Note the COL is right around 2.20" and measuring 1.80" from the base to the start of the forward band was right on in my upper. I tried a little further out initially, but some of the fatter boolits got bound up a little.

Most of these guys weighed in around 181 grain with some up to 184.

Here is one of the max load AA 11FS:
265458

And my initial test box:
265459

Will report back. I'm really curious to see how close W296 and AA 11FS are. Should shoot 'em on Monday.

[cwlongshot]

Looking forward to it 44!!

I hit the range last might with some loads myself. I was excited to try some
Subs.
I had one loading with two bullets. Herco was the powder. Winchester SR prime and a 270 & 235 Cast bullet. QL suggested 7g for a 1100 fps vel. It was nearly spot on with a 1060/27g & 1090/235g.

Accuracy was 1.5" @ 50 using top Of bottom duplex post as aiming point.

The 270 showed just a bit of tail yaw. I kinda expected this. But the 235 was perfect round holes a d just a tad larger group. If I give these 270's a bit of a kick in the **** they should stabulize. As I am NOT shooting theu supressor Im not at all limited to this velocity. Super happy with this!! That 270 is delivering 1K FPE on target at the 1100 fps. Super light recoil too.

[Hanzy4200]

Its a Accurate mold. They will shoot great. I had a iron Accurate mold out today trading off between a Lyman. The Accurate casts SO much better. Sprues just slide off and the bullets drop with ease.

[cwlongshot]

I was testing more subs today.

Those 7g loads had a bit of a yaw. So I tried 7.5 & 8. Out at 100, the 8g with still under sonic at 1090 and shot real well! Tightened up to under 1" @ 50. Out @ 100 I didnt have a solid aim point so my groups where just 4+ but that yaw was just noticeable. Im pretty happy. Im gonna go .5 more and see what 8.5g does. Should hold under super.

I am real happy with this powder. I loaded up a the 230's with more Herco and these where doing 1475 fps and also shot very well.

Ill be loading alot more of these!!!

CW - funny enough I bought a shotshell loader the other day and got a nice keg of Herco -- since it seemed like a good powder (that was available) for shotshells... Maybe I'll see what these 180s do under it... Tomorrow I get to test those W296/AA11FS rounds, and some shot shells AND a pet project 'trail boss' load in 10 mm...

It's gonna be a fun day, I think!

[cwlongshot]

Good luck!!

Im really impressed with Herco!! I havent used it in near 30 years!! My cardboard tube container says 10.99$.

What is the baseline shell? ie what is this ctg made from?

[mehavey]

What is the baseline shell?
ie what is this ctg made from?If you're speaking of the 350 Legend, it's rim is based on the 223/556
But the body is larger diameter.
It is therefore it's own design.

[cwlongshot]

Correct.

This isnt made from anything. But its case head dia is a 223/556. The legend case is more tapered so its fatter at the web.

CW

[44Blam]

Well... I didn't get any #s today... My stupid chrono is a *** - at least some of the times.

I did shoot some and my max load W296 loads were showing signs of high pressure (24 grn w296 with the Accurate 36-180LG) but the accuracy was good.

The AA11FS at 24 grain had less pressure - also good accuracy. I think I'd load 23.5 or 23.3 of W296 and maybe go up to 24.5 or maybe 25 of the AA11FS. And I'll do that when I can get good accurate chrono info. :-/

Trailboss in 10mm is fun.

AND the good news of the day... My first shotgun reloads were GREAT. It was 1 1/8 oz #4 birdshot under about 26 grain of herco. I was by myself at the trap range so I had to load the trap flinger and hold on to my shotgun. Then pull the handle, raise the gun and *POW*. Took me about 20 rounds to get 3 in a row... But after that I was hitting most of them. :D

I thought the 350 Legend case was less tapered on the outside but more taper on the inside?

it is a rebated rim cartridge. The taper is the outside.

44Blam, have you done anymore testing yet. I am still considering getting this mold. Interested in velocity #'s if you have them.

[mehavey]

Tom's ACC 36-180LG:
https://i.postimg.cc/kXYTSTSz/350-Legend-ACC36-180-LG-Red-Mirror.jpg
QL Predicted Velocity above was 2,068fps @ 95°
Actual velocity (LABRADAR) @ 99° was 2,096±05 SD

It shoots just as well/same load, with ALOX

44Blam, have you done anymore testing yet. I am still considering getting this mold. Interested in velocity #'s if you have them.

The load(s) that seemed most accurate and had the best #s was 23.5 grain of either W296 or AA11FS. They were both very consistent around 2175 fps. Higher charges got a little erratic and lower charges were also erratic. Also, the 23.5 grain was not compressed, but was around 90 or so % of the case fill. In my magnum revolvers, this is also where I found a sweet spot...

I've got 100 rounds of that Accurate 36-180LG (but without the lube grove) loaded under 23.5 grain of AA11fs and I'm going to do some longer range shooting tomorrow. We'll see where it goes subsonic and how far out we can get it to ding a steel plate. ;)

[cwlongshot]

Since my last post. I have acquired a NOE 360-197 RN HP aL2 mold.

I have multiple alloys cast but waiting for them to season.

I did load some 357 Mag with the bullet. Just 10 pcs. But with a first shot flyer I got a SINGKE HOLE @ 50 yards!!!

WOOHOO Im excited for this one!!

The Bullet is quite close to the Lyman 358430. But only two grease grooves and a .25 longer nose. Same weight.

I love all my Accurate Molds. Tom is the first place I look when adding a new caliber.

[44Blam]

Well, this mold works. :)

This is a boolit going about 2175 fps to a pig at 300 yards:

It is but an example of what Moderate hardness, Properly-sized (.357), Coated-Cast projectiles can handle.

Mehavey, did you have pressure signs on the case/primer? I shot a bunch of rounds that were 24.2 grain of AA11FS (similar) and shot some (I think 5 of the W296 at 24 grain) but with an OAL of 2.195"... (Shooting an AR style rifle) But I didn't see pressure signs in the primer/case...

[mehavey]

Np pressure signs of any kind.
It is, in fact, within Hodgdon's loading spec for 180Win jacketed

but their loading is at
- 2.11" OAL (mine is 2.23")
- 2,075 fps (mine is 150fps faster)
- Out of a 24" barrel (my rifled portion is 15")
- Jacketed (mine is cast and likely seals barrel better)

All he "analytical" signs are that it's "operating outside of manufacturer's spec"
But no physical signs.

I wouldn't ordinarily get too excited.... but.

I ask because my AA11FS #s at 24.2 grain are:
2163 2167 2152 2211 2216
But 24.0 grain are:
2202 2142 2216 ERR ERR
23.5 was:
2173 2176 2182 ERR 2194

With W296 my 23.5 grain load was:
2158 2178 2184 2196 2176
And 24.0 grain was:
2242 2201 ERR ERR ERR

I saw no pressure issues - that's why I went with 24.2 grain of AA11FS on some loads. I am loading my "standard" loads with 23.5 grain. But my COL is also a little different: 2.195".

[44Blam]

So one thing I always understood about W296/H110/AA1FS is that it doesn't like to be loaded less than 90% cartridge space. (Old info from 44 mag loads).

I almost think I should see what a 4198 load with a full case does...

With this load, I'm sitting at 80% useable-volume/case fill now.
Can't put more w/ H110/W296 into the case w/o going off the pressure charts.

But bullet handles high pressure, and rifle/bullet combo likes those high velocities.
I'll go back and stuff max Volume/Compression Norma-200 into it. I trust that powder
(calibrated QUICKLOAD@lower load says --> 107% Fill/49ksi/2,180fps)

If it quits raining, we'll see.

Wow. I have not seen that much of a spike but I found better accuacy / consistency with 23.5 grain - but I do worry a little since my COL is shorter than yours. You are seating 2.23" and I'm seating 2.195" - this is what gets right up to my lands and cycles properly. Just that fact would lead me to believe that I'm pushing higher pressures that what you are seeing.
