6.5CM - 139 Scenars

Recommended Posts

Settled on this for now;

 

6.5 Creedmoor Lapua Small Primer Cases

139 Lapua Scenar Bullet seated with 0.030” jump

42gr of H4350

CCI BR4 primer

 

Put 5 rounds of this through my AI AT today at 100m and ran them over the chrono also;

 

2726, 2726, 2723, 2736, 2732fps. So SD of 5.3 and ES of 13. They are going quite slow really, but are consistent and I’m happy with the results I’ve been having for a little while now.

The accuracy is there, there are no pressure signs at all (easy on the cases) and they are still well above transonic at my usual distance of 900m (or 1000yds depending on which range I’m at). So there seems little point in driving them harder?.

The 100m group today was 0.43moa and I’m not dissatisfied with the ETR grouping from last weekend at 1000yds at Bisley. (Shame the wind took two off to the right!).

Another massive thumbs up for them 139 Scenars, good job I bought a box of 1000 I guess!

Trouble is you can’t get H4350 any more, so although I’ve still got 3lbs of it, there’s not much point in carrying on with load development with it. 

Ive switched to RS62...

It’s a shame about the demise of H4350 under REACH.

I have a small stash that will see me though the life of this barrel so I’m good to go with this load for a while yet!

RS62 would be the next powder on my list to have a play with I think! It has some great reviews on here.
