The internal mag length on my Sako .260 Rem is 2.965". Loaded up some Lapua Scenar 139gr for a 600m shoot at the club. Went with a COAL of 2.960 or, if you will, 2.373" to the ogive. Best groups at 100m were around 0.12 - 0.15 MOA. Also having a go with Nosler 100gr BT's. Have chosen a COAL of 2.900". Best load so far is grouping around .30 MOA. Haven't chronied this yet but it's looking good for a longer range varmint load.
"Looking good for a longer range varmint load."
I'll bet it is. You'll be shooting them in the eye with that kind of accuracy. Well done.
