I picked up the pistol buffer tube off ebay and stole the DPMS Hi Pro from the 45acp. Just got a batch of upper receivers from AIM and Lowers from Palmetto State Armory when they had them on sale. $49 for the lower and $29 for LPK. We'll put a couple together and see how they do. Now I'm out of FF tubes so that explains the picture. Left my last pistol scope up north so will put this on the 256 on my next trip. The 256 is just beggin for something, need to figure out what that is. Function from stock mag is just fine. I need to try some 25-20 bullets but probably will end up with a Fireball and Tok version.
Picked up two bullets for the 256, a cast 60gr and a Hornady 60gr JFP. Loaded up the JFP with 17.3 gr of H110. Don't remember what QL said but should be around 2600. Here's the sight in target at 100 yds 2 shots at a time. I think the scope is a Bushnell 2x or 4x
Going to load up more of those and the 75's and see what happens next.
Those weren't the cast, I haven't loaded them up yet, just wanted the option. Those were the Hornady Jacketed Flat Nose. I do run the crap out of 9mm cast maxed out in the 9x23 using Lee Liquid Alox, good stuff!
OK, a question for you when you get the time. Did you have to modify the barrel extension to get the flat nosed bullets to feed? I have some FN bullets but have not tried them in my rimless 256WM setup because when I got them they looked too much like a "No Go" through the feed ramps on the extension. I figured why load up the ammo only to find they won't work and have to pull all the bullets.
I have not tried reloading 9mm but I have done a bunch of the 7.62X25 using cast bullets but I didn't use the Alox on them since they where already lubed. I also did a bunch of 5.7X28 in an AR I have (Not an AR57) and used a fair variety of weights and shapes in 22 cast bullets -- I resize them to .225". I use the Alox on them and they shoot really good so I'm thinking Maybe I should Alox the 7.62 cast bullets and also get a Lee sizer for the bullets to make sure they are uniform. I install gas checks on the 22 caliber cast bullets but there is no gas check seat on the 30 caliber cast bullets I use in the 7.62X25 so I keep the velocity down. Maybe I should look for 30 caliber cast bullets that can take a gas check -- I don't cast myself. I use copper gas checks but have tried aluminum gas checks with no real difference in accuracy that I could tell. Only problem I had with aluminum gas checks on the 22 bullets was every once and a while the GC would come off going through the Lee sizer -- never had that happen with the copper GC's.
the extension on the 256 is bone stock. I thought I would have to open it up a bit but I think the close to .22 cal + the longer case allows it to work. They fed 100%.
Thanks for the info! There are 60gr bullets available but they are flat nosed and I figured they were a waste of money. I have some 75gr FN bullets that are "new in the box" that were given to me and I'll try them first in some dummy rounds to see how they feed for me.

Depends on the mag also. I tried the 60 FN in a 6.8 mag and got nose down jams a couple of times. Plus the upper is not an M4 so that doesn't help. Ran a few more 60gr FN loads and still in that 1" - 1-1/2" group size. Did some 75g that I had loaded up and they were 1-2" groups. Don't really know if I'm getting the full potential with the 4x scope. I'm basically guessing at center of target.
I've got the carry handle upper receiver so I put one of those Colt Clone 4X scopes on so I'm in the same boat as you. The picture below is my 256WM carbine shot group when I had a scope with a little more power and a flat top receiver but the scope really looked out of place.
The bullets I used were Sierra 70gr with the plastic tip like a V-max tip only it's green. I'm going to shoot the 256WM carbine again this weekend to check how well the Colt clone scope held zero.

Ran a bunch of brass through the vibratory cleaner and just finished cleaning and sorting, while enjoying a cold beverage While looking at all the brass, one of the calibers just looked "right". The .223 looked too long and the 22 RE looked too short. The 45 acp looked to fat and the 9mm looked to small. The 300 Blackout looked like its head was too big for its body and the 30 carbine looked like its head was missing. Then there was the 256 WMR.............. And maybe the 9x23 or 25, or 27
This one is also sitting in the "256" pile. The upper has been handled by 1000 gun show people all thinking "that's cool", but that's about it. Time to do something about it... Yea, "next week", I know....

I have a barrel for my Contender in 256WM, with the poor selection of bullets I just don't know if it is worth the trouble. I like the idea, don't get me wrong. Even more so in a Fireball length, which is just a little longer than the original. Then too the Contender is a 10" barrel so that hurts the ballistics of the cartridge. I just wish it was easier to find .257 bullets in the lighter weights. In my barrel I can't even get the 87 grain bullets to stabilize. Oh Well, that is what the 25-06 is for.
Exactly the issue Paul. The selection of bullets is way too big for the size of the case. I switched to the 1:14 twist from the 1:10 for the 257 ARS and it does ok with the 75 - 87 gr bullets. The Win Mag I have runs small cast bullets ok, but again, to what point? A 40mm case length will probably be required to get any type of power out of the round. When you limit the power and have to run a mag adapter, its just one of those pointless exercises.....

I wouldn't say pointless, it seems more like fruitless. The point is research! And at some point some part of it might yield a correlation to a current project but you don't know until you find the place to apply what you have learned from the development of the project.
