Data is scarce for HiTek coated 18 HBN 240 gr RNFP and SWC data.

Anybody have source of data for medium/hard cast COATED bullets for the 44 magnum?

Again, these are 18 HBN hardness AND Hi Tek coated.

My googlefu is not coming thru for me.

I purchased these from Missouri Bullet Company:

.44 Smasher - Hi-Tek
#HT-430240H
.430 Diameter
.44 Magnum
240 Grain RNFP
Brinell 18
Bullet OAL .686 +/-
For Magnum Loads
Hi-Tek 2-Extreme Coating from J&M Specialized

.44 Elmer K - Hi-Tek
#HT-430240EK
.430 Diameter
.44 Magnum
240 Grain SWC
Brinell 18
Bullet OAL .747 +/-
Keith-style, but with bevel-base
for reloading ease

I'm running 800-x. Lyman has data for cast bullets. I just used data for a 240 grain cast of similar shape.
I've used jacketed data for hitec coated also. But only do that if I can't find appropriate cast data.
PSA A 4" 44 mag and h110 aren't friends.
 
I use these MBC bullets or very similar with 18 BHN. In my M629 6.5" using H110 I've pushed them to just over 1,460fps and using AA#9 got right at 1,440fps. No issues at all, these bullets can take it. 2400 and Universal also work well for acuurate mid-velocity rounds.
 
Are you wanting to push them hard? Or just a pleasant target load? I've shot thousands of each over 7.3 grains of TiteGroup, light crimp. Tack driver, and pleasant shooting. Right about 1000 fps from a Blackhawk 7.5 inch. The RNFP's are my go to plinking round for 44 Mag. The SWCs are a little more accurate, and cut cleaner holes in paper...but the lip hangs on lever guns now and again.
 
L'il Gun is great, if you want full power magnums.
I use the cast bullet loads and work up. The Hy-Tek bullets shoot great.

I don't load Trail Boss so "HOT"
I shoot the 185gr @830fps with 6.4gr
 
Thank you. This is the first time, that I needed data from fellow reloaders.

As these bullets are middle of the road hard AND coated, makes a BIG difference in the load.

Will end with a load in the middle. Not too slow, not too fast.....but.....juuuuuuust right. :)
 
Found time to shoot two strings using the modified Audette load ladder method.

Both bullets seated to 2.600".

Started at 12.2 gr and top load was 14.0.

Shot at 15 yards with excellent results across the board. Will be loading at 13.6 gr of HS6 with both bullet flavors.

Again, thank you for the help with Hi Tek COATED 18 HBN lead bullet load info.

I would be very, very careful with L'il Gun in revolvers. There are better powders on the market:

Here is the post from one of our members on this forum

Hey all, I had a thought on a subject that I wanted to run up the flag pole. It's been documented, and I have seen personally in 2 of my revolvers (44 Mag & 460 Mag), that handloads using Lil' Gun powder lead to very fast forcing cone erosion & top strap cutting.

Since link in his post isn't working, I found text he mentioned on another place:

"Here is a post from Bob Baker of Freedom Arms:

We have seen numerous barrels damaged by using Lil'Gun. According to customers, some had as few as 30 rounds using Lil Gun through them, some had several hundred. Before we figured out what was happening one customer had sent his gun in for a new barrel. Then 600 rounds later it came back for another new barrel.

A couple years ago we did a test with a M83, .357 Mag. using Hornady 180 gr. bullets. We loaded 50 rds. of three different loads. One was a heavy H-110 load and the other two both used Lil Gun in different quantities.

We fired the H-110 loads first, then cut off the threaded end of the barrel. Rethreaded the barrel and shot one of the Lil Gun loads then rethreaded the barrel and shot the last Lil Gun load.

We found even the light load of Lil Gun caused the gun to get extremely hot. The heavy Lil Gun load had the gun so hot the only place we could touch the gun was on the grips and they were very hot.

Under magnification the surface appeared to have heated to a point of flowing using the Lil Gun loads and the heavy load was worse than the light load. This is probably due to Lil Gun having about 10% more nitro glycerin in it than H-110."

11.5 HS6 and a Magnum primer. 10-11.5 Unique. Should equal in velocity with accuracy edge to HS6. Use magnum primer.
HS-6 is one of my favorites in 44 Mag.

Someone on CastBoolits forum got me started on it several years ago, it truly is a wonderful powder for "not full power" loads.

I use a Winchester LPP, they claim their primer is good for regular or Mag loads. I've had no trouble with that primer and HS-6.

There is plentiful data out there for 240 gr RNFP/SWC in .44 mag. Hardness and type of lube is pretty much moot compared to profile when looking for a powder/charge rate. If your bullet profile is similar to a published load and you start low and work your way up(as we should with every new load), you should be good to go. Reloaders have to extrapolate data for different bullets all the time, especially nowadays when everyone and their brother is making "hard cast coated". One reason most of those manufacturers do not publish data is because they use a common profile and know that extrapolated loads will work just fine.
