6mm BR Norma H-4350

[NC/Br Shooter]

this is my results for today. I originally dragged out my chronograph to clock my 90 grainers with the Ar comp vs RL15 and see what it took to get equal results. That was a fun experiment. All in all though thats not what Im posting about, Here is what I got with 108s with 30.5g of h4350 6bra. I dont know the math exactly, But Here it is shot by shot

These results are way different than what I had got last month. Last session, I had a different chronograph. This load shot a .199
.238 and .255 3 shot groups. But its considerably slower

Didn't you shoot your record small 300 yard group with h4350?

shot one with imr and one with h,
this last go round is from a new lot of h4350 two tenths lower, shoots good at 100. im going to load up 30.7, 30.8 today, with this new lot, and see how it goes. Like , I say, this newer chronograph seems to work ok,
Where should my chronograph be in relation to the muzzle? How close or how far?

My point is, that is shoots tiny groups no matter the speed

So where are all the folks using 4350???? I can't be the only one trying this.

I'm here, But, I"M shooting a Dasher People say it's slow, but, I"M pushing 115's out @ 2820. Not that slow when you consider 105's-108's are going out mid-2900's. Bullet efficiency does the rest. I may have to call a little more wind, but if the load is always consistent, it's easier to do.

Yes, You are correct

Interesting thread, I see in Sierra’s sixth manual for the 107’s they show the 4350’s and RL 16 for faster speeds.
