I just built my 6x45 AR and have had great luck with two different 70 grain bullets with BLC2 powder.  I got good results from most powdor loadings.   I think I have a viable varmint round with these lighter bullets.  My barrel is 20", rifle-length gas with target crown.  Flawless operation!

 

I'm also looking for a bullet appropriate for deer.  I bought some 85 gr bullets (Hornady Interbond) and loaded them also with BLC2 powder from the 6x45 load data available on this forum.  I loaded a good range of powder but got dismal results.  6" spread at 50 yards!!!

 

Can anyone recommend powders that might be better suited for the heavier bullets in this 1x9" barrel?  I'm looking for accuracy in the 85gr range.

 

Are there appropriate 6mm bullets for deer in the 70-75gr range?  (The 6.8 hog killers say V-Maxes do fine on deer but are marginal on hogs.)

 

Thanks in advance,

Ok, I find that Barnes is making the TTSX in 80gr for the 6mm!  Does anyone have 80gr pet loads?

One word of caution on those solid bullets.  Make darn sure you strip the barrel completely clean or you wil get terribele results.  Look to the Accuarte Arms line of powders or the 6X45 laoding data spread sheet posted here. It will give you some nice loads. I have never found BLC2 to do anything woth writing about in any 223 based cases. Velocites have always been in the toilet for me. YMMV Look at 8208 or CFE 223 for some good stuff.  Hodgdon web site  wlil help you out on that.

Ok, I tried several loadings of Varget with the 85gr Accubonds.  MUCH better results.  About 1 1/2" at 100 yards.  More range testing coming up soon.

In my 6x45 Savage build I run 80/85/95 g bullets for antelope out here.

6x45, 1/10" twist, 24" McGowan SS bbl. I ran a P3, 20"  BHW 1/10" barrel in my AR15 with almost as good results.

Im looking to built another 6x45 w/the BHW bbl in 1/9" twist for another bolt gun build this year.

 

80g barnes ttsx load is 26g H335, 2.280" col 2814 fps, .550" @ 100 yds

80g ttsx, 26.8g w748, 2.280" col, 2826 fps, .650" @ 100 yds.

80g sierra JSP, 25.3g H335, 2927 fps, 2.280" col.

95g Nosler HBT, 24.3g H335, 2.280" col, 2653 fps, .670" @ 100yds.

I also run the 85g sierra GKHP w/24.3g H335, 2.280" col, 2819 fps 

 

I have used blc2/aa2015/benchmark/X-terminator powders as well w/the heavier bullets but overall h335 gives me the best results with 80-95g

My go to powder for 55-65g coyote loads is X-terminator.

In the AR15 I had my COL was 2.250"

Are the loads you just referenced what you load for both guns?

^^^ Yes, with the only exception being they are 2.250" col in the AR15 to fit the magazine.

In the AR15 6x45 20" bbl they run about 300 fps slower.

 

Ar15 6x45 heavy bullet data @ 100 yds, 20" BHW P3 bbl.

COL 2.250" Use at your own risk.

 

85g SGKHP, 25.1g  h335, 2710  fps, .500"

85g sgkhp, 25.5g blc2, 2467 fps, .620"

85g sgkhp, 23.5 aa2015, 2682 fps.

80g speer JSP, 24.4 aa2015, 2914 fps

80g speer JSP, 27.6g w748, 2941 fps.

95g nosler HBT, 24.3g h335, 2417 fps.

 

Everything above shot from .380" to .730" @ 100 yds.

I would look at RL15 and H4895 for heavy bullet loads. My rifle seems to shoot quite a bit fast than the above loads. Look for the 6X45 loading data link to get a great grasp on how hard it can be pushed safely. BHW barrels love the heat.

I just finished my ar 6x45 2 weeks ago (thank you BHW)  16 1/2 inch ss barrel. I loaded up test rounds for 55,60, 80 and 90 grain bullets.

I used RL7 with a min start load of 23 grains and maxed out at 25. Those loads are across the board versatile and can be found in the Accurate manual.

I was shooting 1-1.5 inch groups at 200yds with the 90 grain bullets on a bipod/shoulder orientation. FYI this load shot zero at 100 and 200 no scope adjusrment

As with all powders the length of the barrel can affect which powder will work best.Longer barrels will usually perform better with slower powders.

Accurate 2230/reloader7 works great in the lighter bullets up to 75 grains.

My next test will be reloader15 and 100 grain bullets. I will post 100yd targets after I get back next week.

Sounds great. They really are a pleasure to shoot. Plus you save so much paper.

The best load I have come up with for my 20" barreled 6mmX45 is 23 gr of IMR 3031 under a Sierra 85 gr Game King. I am getting .5" five shout groups and 2600 FPS.
