The 17.5 gr. load I have listed would still be fine as a starting load in Starline brass...

Yes, Remington brass is stronger.

................................................

Starting load -

CASE: Remington or Starline 357 Maximum brass

PRIMER: Remington 7 1/2

POWDER: Winchester 296 / 17.5 gr.

BULLET: 200 gr. Spire Points

COMMENTS: You can also use this same load with H-110 powder...

just got back with 9 lbs of Lil Gun, bought out the last that was in a gun shop that recently close. Got it at dealers cost so bought all he had. All he had left for primers was 1 flat of Remington 7 1/2 and 1 flat of Federal 205. Only other primers he had were CCI No41 5.56 Military Primers. He claimed that they are hotter than standard small rifle, more like Remington 7 1/2 Bench Rest primers. I am not familiar with CCI No41 so decided against them until I check them out.
Anyone have experience with CCI No41 primers?
I am loading 5 rds of each, Lil Gun, 296 and H110 tonight starting with 17.5 gr loads, hope to try them tomorrow.

Good score on the powder!

Keep us posted on how your load development goes...

With the 180 XTP, I settled on 22gr of Lil Gun for 2050fps in 16.5" barrel in Rem cases and 7 1/2 Primer. I've found the Lil Gun shoots almost as well as H110/W296 and 75-100fps faster in my gun in both Maximum as well as Magnum loads with the 180 XTP's, but H110 has superior accuracy and equal velocity in all of my loads using bullets <180 gr.(which are 158XTP/FP, 140FTX, 125XTP/FP).

Long time "Lurker" here but I finally jumped in I am now addicted to the 357 Maximum.  This forum has been invaluable.

I have a TC Encore with an MGM 16" 1 in 14 twist (since I shoot heavyweight suppressed also) and a brand new Tromix AR-15 with a 358 SOCOM upper (essentially a 458 SOCOM necked down to 358).  Its pretty much a semi-auto 357 Maxi.  I swage my own projectiles using Brian Thurner's (BTSniper) wonderful swaging dies, recycling annealed 9mm cases and creating jacketed bullet weights from 110gr to 290gr.  I have point forming dies for JHP, S6 Ogive Flat Point and Truncated Cone.

I have quite a bit of Vihtavuori powder and I am developing some loads for the Encore presently.  I know there are other powders better suited for top performing loads, but I am not necessarily looking for ultimate performance, but rather boringly accurate and useful hunting loads effective out to 150-200yds at most for this fall's hunting.

I have settled on the following loads to continue workups (all have room to increase charge weights).  I have only shot them at 50yds to begin accuracy testing and collect chrono data:

Bullet: 358dia - Swaged 182gr JHP
Brass: Starline
Powder: VV N110 - 22gr
Primer: CCI SRP
OAL: 2.25
Chrono: 1964 FPS / 1559 FPE
ES: 52 / SD: 19

I am not sure why, but this cartridge is super exciting to fiddle around with and incredibly versitile.  My large bore, heavyweight guns are in the back of the safe pouting.

Meatpuppet,

welcome to the forum and God Bless.

Those are some interesting looking swaged bullets you have there. It looks like your initial testing is showing some potential for this Fall's hunting season. Have you done any type of expansion testing with your swaged bullets? I hope you will continue to give range reports with both your bullets and loads...

Thank you David.  I'm really exited about the potential here.  

I'm going to try some water-jug testing once this annoying Hurricane Irma gets through South Florida. I do know the subsonic 230 grain opens up with all that soft lead out front. I've dug some out of the backstop before.  I'll include photos and do proper 100 / 150 yard testing as soon as I can.

I'm learning that the grain weight of 9mm brass is all over the place, so I'm going to separate brass by headstamp next time I anneal and swage up some projectiles.

So darned interesting!

Since I am a 6mm nut, I use to form and swaged my own 6mm bullets, and learned a lot from it. Now days though, shooting 9 different cartridges in various 6mm chamberings, without exception, they all shoot the same bullet - Sierra's 85 gr. B.T.-H.P. Game King...

Please keep us posted!

I have a 21" 357 bbl cut to 357 Max by Mike Bellm & I have forgotten who its mfg by? It"s been so long ago Bellm did it 3 or 4 years ago maybe longer it is in my basement somewhere. Oh, I believe it"s a Bullberry Barrel,  after reading some of the posts on here I may dig it out and give it a try.

The 357 max is an amazing round.  With David gunsmithing  I have this max.  The barrel is 16.5 inches.  I restocked so my wife could use it for Indiana deer but she has never went with me.

I have a CVA V2 Pistol 14" in 357 rechambered to 357 Max by David.
Over the weekend I worked up to and shot 3 rounds with 200g Sierra RN and 23.5g of W296.  Primers were beginning to show some minor flattening, but these bullets shot very true.

Am I pushing my luck with these loads ???

Thanks,
Steve

How difficult is extraction? Will the fired cases just fall out of the chamber or does it take considerable force to remove them?

If the cases do not stick in the chamber, and this load shoots good, then shoot it. I however would NOT shoot this load in hot weather...

Thank you for the feedback David.
The extraction was as normal...no sticking.
Now I know I'm right on the edge and weather can become a variable.
Never considered that before.

Regards,
Steve

I've been playing with the 357 max for a little over a year now. Encore frame and a 24" MGM barrel. I've been a rifle cartridge reloaded for many many years and the max case dosent show any pressure signs as far as I can tell, until you go to seat a primer in the cases when reloading them for the next round of fun. The only powder I'm running is Lil gun, tried some h-110 and really didn't like it. Shooting my load of lil gun over my chronograph with the 180gr speer flat point hot core i get a consistent 2450 fps. Give or take 10 or 20 fps, shoots very well if I do my part. The brass I'm using is Jamison right now, not real happy with it because of the enlarged primer pockets but not real sure if its the load or the brass right now cabelas has Remington 357 Maximum brass get on there website and look it up I just received 2 100 rd bags of the stuff and I think it's being dropped shipped from remington. On sale for $31 something a bag. The charge I'm running is a very compressed charge. And I have to run a pretty heave crimp to get the gun to shoot good, it's a pretty heavy compressed load..

Yoda,

welcome to the forum and God Blees.

Jamison brass is the worse brass I have ever seen, bar none!

When you get your Remington brass in hand, throw the Jamison brass in the trash! The only thing you'll be missing is the headache from not having it around...
