I finally got a chance to get some range time in with my Big Boy: Mr Ambassador!
I'm also going to throw this out just because. For a part of this testing I had someone in the next lane shooting a 308 with a compensator. It did affect my concentration some and some of my groups do show this. So some of these groups were me not just powder difference.
For the last year or so I've been loading very light cowboy style loads with Unique Powder. I'll start with that.
This was just kind of a control comparison. I'll soon test this load with different bullets.
Anyway 44 mag, Berry's 240 gr target HP, 8 gr Unique.
I shot over my chrono.
low = 945 fps
high = 1,099 fps
avg = 1,005 fps
3" group at 50 yds. The black part of all these targets is 8".
Next up is a new load and a new bullet for me.
240 gr Missouri Bullet Co lead rnfp, 7 gr of trail boss
low = 935 fps
high = 981 fps
avg = 954 fps
3.5" group at 50 yds
3" group at 50 yds
And just trying to get the same load on paper at 100 yds.
And the surprise of the day. Berry's 240 gr copper plated rnfp, 7 gr of Trail Boss.
Check the speed difference from above. Exactly the same load just a different 240 gr bullet.
Low = 720 (fluke)
high = 830 fps
avg = 801 fps
2.25" group at 50 yds.
2.75" group at 50 yds
1.5" group at 50 yds. 5 shot is flyer just off top of paper.
Add 2 full turns up on my rear Skinner peep and 1.75 ' group at 100yds!
This is the best 100 yd group I've ever shot with this rifle.
Over all I'm very pleased with the results. The combo of 7 gr Trail Boss and the Berry's plated bullet have a lot of promise. This is a light load! Like shooting a 22 recoil wise. At these speeds you shoot then wait to hear it hit the target at 100 yds.
I should also note that with my eyes I don't shoot at 100 yds much lately. But I was seeing it well(for me) yesterday.
This is the 1st time I've used Trail Boss. The loads seem a little more consistent than Unique. I weigh every charge! Can't wait to try the 45/70 loads I loaded with this powder.
