105 Hybrid vs 108 BT

[jsimonh]

I've done some reading about it but haven't found what I was looking for.

I'm fixing to start load development for my Dasher and ordered up some 105 Hybrids because my last one shot them so well. Matter of fact that's all I shot out of it. I thought about trying the 108, but I don't see any advantage of it vs the hybrid.

Can someone enlighten me on why anyone would choose the 108 over the 105?

108's are easier to to tune, when the throat grows and you haven't re checked the bullet oal, they will probably still shoot very good, very long bearing surface gives a lot of flexability when the throat does grow.

Yup, the 108s are my favorite 6mm bullet. in the 6xc, they are my 300 rapid, 600 yard and when I shoot an any gun at 1000, my 1000 yard bullet. Most of my PRs have been shot with those bullets. Just super easy to load for and I run the same load in all of my XTC and LR rifles. No clue how far they are jumping in most of the bbls...the bullets dont seem to care, so neither do I. the 105 hybrids, like some of the other hybrids, shoot great in some of my rifles, but not all. the 108s just dont care, they are the honey badger of the 6mm bullets, imho.

So switching from

So a switch from VLDs to 108s would start with the same basic load and add a little jump?
thanks

108’s generally are more consistently accurate. Easier to tune.

108’s do require a longer freebore in my opinion...135 or .155 would seem to be ideal in a Dasher.

In a straight 6BR Hart bbl I shot the bbl out using 105 Hybrids, very accurate and not fussy. I switched to a Kreiger with the same reamer and I could not get the Hybrids to shoot. I wound up loading Berger 108's jammed and it is a tack driver. 597 35X in the last 600 yard f class match. My freebore is .094. It grows fast enough on its own, no need to go any longer.

No, 108 have a lot more bearing surface and build more pressure. Back off the charge some.

Having experienced this, please listen to Alex, unless you like the idea of buying brass a whole lot more frequently.

I’m preparing to try the 108 bullets... any recommendations on how much to reduce the powder charge weight versus for the 105?

I have nothing but good things to say about the 108s, I have the, loaded right at the lands and haven’t adjusted a think in over 400 rounds since barrel break in.

Great news! What powder and charge weight are you using?

 

[gme]

the 108 is the easy button

Mine is a straight 6br, 30g varget and cci450s. Measured to the lands the Hornady oal gauge and literally can’t shoot any better.

.5 gn or maybe more

Thanks to all for the 108 grain load info!

Should another ladder be shot?
thanks
