Going Wild for Wylde Chambers

[NW CO Raptor Feeding]

I am into a reloading mode right now....have about 3K pieces of brass to run thru a single stage press. It got me thinking about chambers and what works and what does "OK" Recently I have built two complete guns for people and both have been Wylde chambers. The first is a coyote/Varmiter for a friend. He did not know much about BPAG's (black plastic Army guns) so I gave him the run down on the important parts and he wanted a reliable accurate gun. I started with a AR Stoner barrel 20" A DPMS Slick side upper (if it wont chamber....you really dont want to fire it) A Rock river bolt, and Model one sales free float tube, basic gas block and tube. Super simple upper with a fantastic Barrel for the money. The lower is a Rock River, with Palmetto State LPK. Palmetto is my goto place for lower Parts kits and Stocks, excellent quality, for basic LPKs. The Fire control group is standard mill spec, I usually do a basic trigger job, polish pins, internal surfaces and the face of the hammer, I dont touch the sear or disconnector, as these are easy to go to far. I cut about a 1/8" off of one side of the trigger spring to lessen the trigger pull a touch. I back that all up with standard A2 stock and buffer, and spring. The fit and finish of the Palmetto LPK is fantastic. That all topped off with a Rock River Canta. Scope mount. The customer supplied the Scope, not my choice but a nice 4-14 does well. I like the 40Gr Vmaxs and this 1-8 tube works really well with them, yielding 1/4" groups no problem.
All this really needs to be a outstanding build is a better fire controll group, a Rock River two stage for $85 for be a first choice. Totall build is $750.00 for a solid varmiter that shoots.

Hey Raptor.

I recently built myself a Palmetto AR with the 1/8 twist stainless, Wylde chambered barrel. This is my first AR.

I'm also new to reloading...new press and goodies on the way.

Question is that I was under the impression that the faster twist barrels "needed" more grains in the projectile. As a matter of fact, based on what I've read, I felt I was at the bottom of the weight range for my barrel with the 55grainers. Can you school me as to why and how 40 gr works so well with this fast of a twist?

Thanks

You know, I dont have a highly technical answer for that. What I do know in three out of three 1-8 barrels the 40gr shot really nice. They are not 600yd rounds but out to 300 they are mean. Every barrel is just a little different and you will have to test it for yourself. Rock River and AR stoners work, Palmetto I am going to try, I just built a 16" Wylde also. I have been using the same load for both my guns, and have had great results, if you need load info just PM me I will be glad to send it to you. I have only used the Hornaday V-Max bullets.

Not a projectile scientist, but i took physics once and i stayed at a holiday in express last night.
The higher twist rate is needed to stabilize longer bullets, and allow them to maintain their twist and velocity out farther. a higher twist rate still works on smaller lighter bullets and will just stabilize them more. I think it is possible to over stabilize a lighter bullet and cause it to fragment but that is only an issue with a lot higher twist rates and lighter smaller bullets.

again, not an expert and I'm not positive but that's what i remember learning in gunsmithing school :)

If this set up likes the 40gr try some of the 52gr stuff. These bullets were the shit out of my 1/12 colt .625 bbl.
