I also run 63gr Sierra semi’s in my old A1 Sako. Nothing with four legs likes them. Just got some Speer Gold Dot 62’s to give a whirl, they get some encouraging write up’s

Ive used JBM ballistics for ages for trajectory but never noticed until today this Table of Projectile Lengths.

My current batch of Speer 70grain are about .780" where this shows .808", I think Speer have tweaked the profile a little, I noticed this when setting the jump to rifling.

I guess that if you have to substitue a projectile with the same weight, you can use the same or shorter it should still stabilise in YOUR rifle.

OK its crappy day and I have nothing better to do with my time.

The 63gr Sierra was the cousin for the 64gr PMC. Both very good pills. The 63gr superceded by the 65gr GMK. The 63gr gets very little mention or support form Sierra. Strange company but reflective of the machinations that besets changed ownership.
