Home Forums Reloading Big Game Rifles Im new to .264 win mag, your pet loads please!

I know I don't have to, but I want you to feel better about the extra 150 fps


I have one lot of RL-33. In my last barrel, I was at 77 grains for 3250 fps. In that barrel I never got more than 3250 fps without pressure signs. I was shooting the 140 VLD.

That was what caused me to say that it was interesting that the dude who was loading 75 grains was only getting a bit over 3000.

When I started load development in my new barrel, I started at 72 grains, fired 3 shots up to 73 grains and hit pressure way too early for a test so I started over and lower at 69 grains. At 72.5 I had a faint ejector mark and at 73 as well with a bit of a sticky bolt lift. I realize that the old barrel's throat was worn and this was a new chamber causing the difference.

The entire ladder at 550 yards was a node. I simply picked the highest charge under the pressure signs, loaded 3 and shot them at 100. It grouped .3"

At this point I had no idea of the velocity until I shot it for drop data and used Ballistic AE to true it out.

Whoever said it is a "fast" barrel is right. I'm also shooting the 139 Scenar. The barrel and bullet dimensions might have bearing on the results, but some barrels are slower and some are faster. I thought it was interesting. This happens to be a "fast" and "accurate" barrel...
