My out of the box gun was giving 6-8" 'groups' at 100 yards. The trigger reworked to a nice clean 4# and a muzzle break gets me into the 2-3" 3 shot group range.
Win white box 40 gr Varmits 2", 68gr BH match 2.5, 69g Sierra MK with 24.2g IMR 4895 <2" for 3, but 3.5" for 5.
Hopefully the bedding instructions and gas port kit will arrive from Mike early this week and will get me down <= 2" on both the light and heavy bullets, eliminate the flyers and stop the hike to the brass. My 1-4 VXll doesn't exactly allow me to hold the best, but I want to use the 1x for tactical games for the up close and personnel stuff. 4x should be plenty good for 300yd B27's, so I am not replacing it.
I think that I will throw a party when I get there............. 1.5-2", 40's to 70's.

Welcome to the forum Oldjad01. Sounds like you are developing a shooter there. The bedding will get rid of the flyers, and tighten your average groups.

My 9" to 1 turn mini, didn't like 69 grn bullets but loves Sierra 63 grn SP 1.15" avg. groups, also the 45 grn Winchester factory's 1 1/12" avg. I couldn't get it to shoot 55 grn very well either (2" groups). I basicly shoot reloads, but also have a low price factory ammo for back up.

I pretty much keep my 3-9x40mm Vari X II on 4x for 100 yd. The accurizing is kinda adictive for me.

Oldjad01,

I noticed you did not mention the gas block. Are you going to refit it, or have you already?

 

[Oldjad01]

I am hoping to get it in the mail Tuesday and will fit the smaller one when I do the bedding. I don't think it helps accuracy unless there is something related to the hammering that the gun takes from the violent action of the bolt.

Fitting the gas block, is lapping the sides a bit so you can gap the gas bolck halves evenly. By gaping, and torqueing the halves evenly some have seen a slight amount of accuracy improvement. If you slug your barrel with a 22 LR bullet you would be able to feel how the gas block compresses the mini's barrel, therefore even gap, and torque at least compresses the barrel evenly, giving better accuracy. I torque mine 24 to 36 in-lbs. Or with a 9/64" allen wrench, tight with even feel, in a criss cross patern, but not so tight as to strip the heads.

Replacing the std gas port bushing reduces felt recoil dramaticly. It will improve accuracy only when rapid firing, as you can keep the sight picture on the bull. I use the largest of the 3 bushings, which is still way smaller than the std bushing.

 

[Oldjad01]

Sorry about the brain lapse, it must have out for a break while I replied to the gas block question. My gas block doesn't touch, there is a gap all the way. I am under the impression that in that condition it shouldn't cause much, if any problem. I don't have a good torque wrench at this time and felt that I would pick one up so that I could tighten it evenly. Guess I might as well lap it and measure when I do it because if there is 1/4" or so to be gained, I WANT IT. Thanks again Jim.

canjungeo, how far does the largest bushing spit your brass? I tried the big bushing from Mike and saw a little difference. Yesterday I tried the medium size and it only threw brass about three to four feet.Wouldn't hlod the bolt open after the last round but who cars about that.

 

[cajungeo]

It depends on the ammo, and number of rounds ran thru your mini.

Using the Winchester 45 grn varmint (3600 FPS) about 10 ft with the largest of mikes bushings. Also about 10 ft with my 63 grn (3000 FPS) reloads. ABout 40 ft with the factory bushing.

You can use the different sizes to adjust to your ammo. I have heard Wolf ammo is loaded light, and is a low velocity, therefore, the factory bushing may function better in a new rifle using a low velocity ammo. As my rifle ages, I will probably use the med bushing. Mike uses the small one in his.
