I've got cases grouped by capacity from 31.5gr up to 34.8gr water capacity depending on the headstamp and how they were modified.  It is important to know what the water capacity of your case is before working up to a max load using someone elses data based off of a different water capacity.  Little changes in seating depths & case capacity can result in big changes in pressure.  With that in mind here are a few of the bullets I've shot with some of the powders I've used in cases that have a 33.5gr average water capacity.  Velocities are for 16" barrels.

When you measure water capacity...is that a case with a bullet seated ??

Empty case- filled to top of neck with h2o. (resized with spent primer placed back in to plug primer hole)

I generally will do a sized cased to get the initial capacity, but after that use a fired case as it's closer to the true capacity since the case will easily expand up to chamber size. Use a the side of a utility knife blade to card the extra water off of the case so that the square back edge pushes the excess water off of the case, then slide the blade back off of the case. Except for the reflective surface the case almost looks empty when doe this way.

All of the MDWS 357AR are 16" right now.

Yes, I use the 16" as the basis for velocity unless stated otherwise.  At 16" you've got the majority of the velocity although you will still see increases with a longer barrel.  Here's one of the loads listed from above that my son got his deer with this year.  The actual magneto speed chronograph average was about 20fps faster. If it's hard to read just push the control button and use the mouse wheel to make it bigger.

Thanks.  So what are we looking at for a muzzle blast out of a 16" barrel.  I have had several 357 max handguns (Blackhawk, Dan Wesson, Contender) and the muzzle blast/eardrum breaking is god awful.  My 22" barrel handi not so much and I am getting 2,180 with a 180grn XTP from the 22" barrel and not much muzzle blast.  But after deer season here in Iowa thinking an upper for my AR would be great.

22KHORNET,  You should be able to match the same speed with 24.5gr W296 and a COl of 2.080" at 56K if that load performs well for you.    So far I've had a 20", 18.5", 16" and a 9.5" 357AR.  The 9.5" is louder than my 44 mag pistols.  The 16" and 18" seem more like shooting a 12ga with field loads.  Not something you should be doing a lot of, but likely most of us have done while rabbit or squirrel hunting.  Don't have my 20" any more and never took it hunting so we always had ear muffs on while shooting it.   Where we hunt about half the time the deer pop out or come running at us so it's either get your ear muffs on or shoot at the deer.  There isn't always time for both.  I would pick a muzzle attachment with sound direction in mind over recoil reductions since these have a mild recoil.  My son has a A2 type flash hider and I have a custom linear comp but haven't shot them side by side without muffs.

Hmm the N120 is slower than RE7 and seems to be working well in the unstated barrel length. EDIT: sorry it says 300mm barrel (12"). 1500+fps in 12" barrel with 200 grain bullet is decent :-).

Hodgdon has H110 achieving 1604 in a 10"

If it bothers you too bad, you could send it to any of us with a barrel already! lol

So what bullets is everyone using.  I am really annoyied that Hornday stopped their 180grn SSP and I do not want to go to the 200 grn bullet so just wondering.  I am using the 180 grn xtp in my Max but not sure how it would feed in a semi auto.

I'm going to try some 180gr Speer hot cores when I get to load development. But to blow out the cases I'm going to use 158 gr XTP's. I agree with you I wish Hornady did not discontinue the 180gr SSP.

In the load data I posted it lists the Hornady 180gr XTP with two different COL.  One for the shorter .075" freebore and one for the longer .150" freebore. Without trimming the feed lips back the blunt xtp profile doesn't have enough of an ogive to help straighten out the cartridge so the longer you seat them out the less likely they'll feed well.  With a reasonable col the xtp's 158 & 180 feed great and are generally what we use as range ammo.

I'm using the 200gr. RN, 200gr. SP, And speer 180HC. I started with powders that yield lower velocity but am already in 35rem. velocity. I wouldn't fear using the 200gr. Even fireform loads have been extremely accurate, when I do my part and slow down. I have been playing with som Berry's 125gr. plated bullets, if I get them to feed, these will be my fireform loads for plinking.

When I first started shooting mine I was surprised how easy it was to match most book loads for 35 rem.   Of course it takes more pressure to get to the same velocity the 35 reaches with a larger case capacity and lower pressure. So far the deer haven't complained.

My concern with the 200's is whether the impact velocity will be high enough for reliable expansion. Deer are not made of phone books but one wet phone book test of a lot of 357 maximum bullets made the 180SSP look really good.

EDIT: Sorry it was a 35 remington test but MV was 2300fps

thanks Bill for posting that.

Custom bullets are never cheap, but I have shot all three of these Fury bullets in my 357 Maxi Encore for the last couple years and they are very very accurate. Only hair test has been on a coon at 50' which needless to say, left a mark, but Dennis can fill you in more on construction etc.

He was working on a 150gr version last fall, not sure where he's at with testing on it.
