Well it finally got here, thanks BHW! I scrubbed the inside till the patchs come out clean and went to start my break in saturday night. Shot 2 times, clean, shoot 3 times clean, shoot 4 times, clean, shoot 5 times, clean shoot 10 times, clean, shoot 20 times. Went home and cleaned it up good. Ran some copper solvent thru it and didnt get any green/blue patches sunday. Loaded some 75gr Amax, 80gr Amax, 80Gr NCC, 90 Gr Bergers, 77Gr NCC. Used new LC brass, Varget, CCI BR4. Temp was 73* my Break in ammo was AP brass, 24gr IMR 4895, 62gr FMJs (2950FPS). They shot absolutly horrible. ~4" group at 100. I figured just a throw together load plus the "wet/clean" bore had something to do with it. Took my heavy loads out there sunday and did some chrono work , group testing. "Varget used in each load" 75gr Amax, CCI BR4 - 2682 FPS 3" Group 24.5gr - 2787FPS 25gr 2830 fps (from here out i used CCI 450 Mag primers) 80gr Amax 23.5gr 2600fps (1.5") 24gr (i didnt ever run them back thru the seater die so they were too long to chamber  ) 80Gr NCC 23.5gr 2523fps 24gr 2623fps (best group out of the bunch, still nothing good tho) 90gr Berger 23gr 2431fps (ran out of targets to shoot, and sun was sinking fast behind the trees so i had to hurry with the Chrono) Goin to work with the 80gr NCC and see what i can make them do. Got a possible scope issue so im swapping the big boy off my 300 WM onto it and see what happens. |

Also, has anyone ever ran into a funny issue like this? 62gr FMJs shot 6" left of where all the heavy bullets hit with the BHW 24" Bull  But shot some out of my RRA 7 twist M4 and they all shot POA. |

Quite a common thing in many rifles. If you shoot enough of them you will see it. Usually not 6" but not unheard of. Are you trying to seat your bullets to the lands or are you picking a random length to load to? I have been using Remington 7 1/2's for most of my stuff and have never tried the Magnum primers. One thing you might try is RL15. I have found in the heavy 6X45's I was getting better velocities and the groups with Varget were OK and consistent the RL15 seemed to want to deliver the goods a tad better. Also I would guess you are not crimping? What type dies? I have been finding that standard dies put too much neck tension on the bullets to really let them work and have gone to bushing dies for my primo accuracy loads for that reason. Greg |

Hum, thats a first for me, ive been shooting my whole life and only time ive had this happen is with a 22LR shooting different brands of ammo. But then again ive always worked with one bullet at a time checking for groups so ive never shot this many different types of bullets out of one rifle in one sitting.
Ive always found out the longest possible seating depth and worked back from there, all these loads were kissing the rifling by .001-.005".
I do have a fresh pound of RL15 that i bought just for this rifle. Just wanted to try Varget first since i knew it worked awesome in my M4 7T barrel along with 450 primers. Ive never worried about velocity, if it dont shoot good then speed dont matter. i just wanted to compare speed differences between the 24" and the 16" but ran out of daylight.
To start with i used RCBS Full length die since the brass was new and i always started full length on the first load, then neck size from there out. ive had really good luck with LEE Collet neck sizer dies in my 22-250, 308, 300WM and .270. 300WM does .25MOA at 600 and the .270 does 1MOA with the other two calibers inbetween.
No crimping, just neck tension.
i only crimp my blasting ammo for my other ARs that get shot alot.
any suggestings with what yall have had good luck with on loads?
Got some 69 and 77gr SMKs and all kinda bullets from 36gr to 90gr to try.

My preference has been to back it off about 0.003 to 0.004 off the lands in my 6X45. Of course shooting mag length you get some real jump. The Sierras are good for that as are the Hornady bullets.
I haven't got up in to the heavy 223 bullets with my new barrel yet but I'll have some comparison stuff for you in a couple of weeks if everything works out right.

Cool, im goin to work on it some more. Loading some more tonight. goin to back off all of them some, should see my scratch pad with all my load data and results.
Making a excel spread sheet and taking my laptop from now on.
Have your BHW barrels shot good from the get go, or did they take a few rounds to get broken in?

Making a excel spread sheet and taking my laptop from now on. Have your BHW barrels shot good from the get go, or did they take a few rounds to get broken in? I break mine in to start but I shoot groups as I go. I've seen that the BHW barrels start shooting from bullet one. They are neat to load for since the poly rifling seems to give you more speed. One think I noticed on this new 223 is that the fired cases are exactly 0.0025 larger than SAAMI minimum. That means I will never have an issue with any factor ammo I shoot, rare for me, and the brass will be worked minimally on the reloading. I have a spread sheet that I use for my chronograph/records work that I would share that does SD, ES, HI, LO and AV plus places for all the important stuff if you want it. Greg |

I use the Hornady Precision Case mic or the Hornady/Stoney Point head space gauge. I use those tools to set my die adjustments to give me about 0.003 space for 100% operational reliability. Greg |

Very nice..
I got some more ammo loaded, also ordered a PRI Adjustable Gas block. I really like the "single shot, bolt action" style with out the gas block right now. Brass doesnt get beat up at all, but with the adjustable gas block i should be able to dial it in and coyote hunt with it, then on Match day turn the gas off and have my "bolt action".
