WFN design for casting/reloading

[RobS]

I was able to get out today and do some work up.  I had to seat to 1.240" so they would fit in my metalform OEM Rock Island magazines.  I don't know if this is how other 1911 single stack magazines are for 10mm or not but figured others reading might want to know.  I did plan on a 1.250 to 1.240" seating depth when I had the boolit drawn up.  Pretty decent day and accurate to around 2.0" at 20 yards off of a bag.  Zero leading with the Hi-Tek coating so that is a plus too.



Firearm: Rock Island 5" FS with 20 lbs recoil spring, 25 pound main spring and flat bottom firing pin stop.

Bullet:  Accurate Arms 40-190R, Hi-Tek coated (three coats), Wheel Weight alloy and sized at .4015

COAL:  Seated at  1.240"

Powder:  Ramshot Enforcer

Grains: 14

Velocity avg. 1150fps


I would like to push this one out at 1200 to 1250 fps and should be able to do it safety using the slower powder.  Additionally I designed this bullet to maximize case volume which will help put more of the slower powder in the case.


I have used 15 grains of Enforcer with the Lee 401-175-TC mold and it is a good 1280 fps load.

Enforcer in 10mm?

Correct.............I have nearly 10 lbs of Enforcer and it's a tick lower than #9

My Accurate 40-195G arrived last week, and I cast a few yesterday - nice mold

Good lookin' bullet!!  195 is nice too... I like the sounds of it... still shoot able from my 40's and not too light for heavy loads allowing for extra PC in the 10.

Well now I have a problem....  I was looking at the NOE but they don't have the configuration I want available and they don't bother answering my emails as to when it might be available... I've bought several molds from Tom and his service is great...

I was about to order the Accurate 40-215F but I really like that newly designed 40-190R...

Winn442...have you chronographed any loads with that bullet yet?  What powder are you using?

RobS...was wondering what you expect for velocity out of your design...that is a nice looking bullet.

Got some loaded but haven't got out to the range yet....damn work keeps getting in the way......and I fatally shot my chronograph a few months ago and haven't replaced it yet....got some Blue Dot in the first few, and will try some Longshot later if I'm not happy with the BD.

Interesting.

I tried it with 180s @ 1,170 and ran into case expansion (no room left in case, was at 110% of capacity).

Guess I should try it with 200s

I was running 15 grains with the Lee 175 grain TC seated at 1.250" and it maxed out case capacity.

14.5 grains today with the  40-190R grain WFN and I was pushing 1240-1250fps.  There is no more room at 14.5 grains with the current seating depth of 1.240"

Well after running a few hundred rounds through I found that Enforcer is just a touch too slow.  I don't have enough case volume to build enough pressure to get a clean enough burn that the unburnt powder after time starts to mess with the full chambering of rounds.  I was ending up later on with rounds not going full battery. 

So onto two different powders.  I used 8.3 grains of Power Pistol and 8.2 gains of Longshot.  COAL was at 1.240" with my 190 grain WFN design, Hi-
Tek coated, wheel weight bullet. 

The Power Pistol load was running 1,218 - 1,244 fps and accuracy was very good.

The Longshot load was running 1,238 - 1,247 fps and accuracy also very good.


The Power Pistol load seemed to have more recoil but burned a bit cleaner.  Accuracy for both was MOA of a shotgun shell at 15 to 16 yards off a bench  .  All in all I'm pretty happy with these loads and plan do more testing but I am leaning to the Longshot load.

My ria fs hc 10mm has run everything through it i can find. I am expecting some rim rock 220 grain cast(same underwood and buffalo bore use) as i REALLY liked what the buffalo bore did. didnt notice any leading but im going to try them with longshot and 800x.

im looking for molds and i may look into that 215.

thanks for the report on how those did!

I apologize for bringing up a potentially dead thread, but I'm curious if RobS is still using these bullets at these speeds successfully out of the RIA. What kind of pressure signs if any are you getting and have you tried AA#9 maybe?

This is the exact type of load I bought my Ultra FS to shoot and carry for mountain lion/black bear backup while out hunting.

I'm not Robs but he is a good friend. as of a week ago he is still running the same bullet 1250 with long shot.  I think he has moved to a 22lb recoil spring.
