Hi folks,
I’ve had a fair bit of help so far, but I’m still left scratching my head and I’m fairly novice. I’m struggling to sort my 6.5 x 55 round. I’ve had some great advice, including Rich at yew tree but I’m struggling. Initially I loaded at the max COAL of 3.15” and conducted a ladder test from 43.5 to 49.2 gr in 3 batch loads. I got a consistent burn at 48.6 gr giving 3127 fps. I know this seems fast, but the primers, case face etc were all good. This seemed to group okay, but gave a very long bullet. I didn’t want to seat the bullet any deeper at this charge weight, as I’m cognisant I’m running hot. Anyway, I loaded a batch of 10 which gave some crazy fliers of 3-4 inch, the rest grouped well….more work to be done. I wondered if this was because the concentricity of the bullet wasn’t good enough, or because I was using new Lapua brass that hadn’t been fire formed to my chamber.
In doing so, I measured what COAL would engage my LANDS, which gave a whopping 3.289”. So at max COAL, I was 139 thou off the lands (which seems large). If I compare a factory Sako 120 gr copper bullet, it’s got a COAL of 3.03” and shoots around 3050 fps. So it’s obviously not uncommon in Swedish to have a huge jump? Is this correct?
Here’s the recipe:
Norma brass
CCI large rifle primer
Reloder - 17
Yew tree TLR 114 Gr
I’m now at that point where I’m doubting myself, so any advice or lived experience would help me.
Im shooting from a Sako 85. Maybe someone has load that works for them in a Sako 85 with the receipt above - that would help steer me.
Thanks,
Rob
