Just wondering if you are seeing pressure signs with RL33 at 72 or 73 grains? I have loaded the Woodleigh 160gr PPSN to 3261fps with the old H570 powder. I would like to try the RL33 with the 130gr JLK VLD as it should be near 3500fps with RL33. Have you tried the JLK bullets?

It has been a few years, but I thought John Barsness came pretty close to 3200 fps with Retumbo, and just a bit faster than that with Magnum. It seems that Magnum gave him the better accuracy and consistency. As a matter of fact here is a scan of some data on this subject: ![[Linked Image]](http://i3.photobucket.com/albums/y83/Idaho_Shooter/264%20loads_zpsr4pnmr8j.jpg) If we compare John's numbers with yours, it looks like RL 33 and Magnum are going to be very close to each other in performance. Magnum does give an advantage in that it flows through a powder measure and the narrow neck of a 25 or 26 caliber case like water. I was curious concerning the bulk density of appropriate 264 powders. So I just weighed a few of the powders in my cabinet. Each weight is from the same W-W 264 Win case filled completely to the top. Magnum .....89.0 gr H 870 ......88.9 gr US 869 .....91.1 gr MagPro .....90.5 gr IMR 4831 ...81.0 gr Retumbo ....82.6 gr RL 33 ......84.7 gr RL 25 ......84.3 gr RL 17 ......83.9 gr H 414 ......89.1 gr Even after we subtract a few grains to make room to seat a bullet, I do not think we are going to see any compressed loads with these powders

I checked my 6.5SLR wildcat. It's the one on the left of the 7mm Rem Mag and holds 90.0 grains of H870. It is made from a 9.3X64 Bernanke. ![[Linked Image]](http://i1232.photobucket.com/albums/ff364/RichCoyle/005_zpsvnwjt7ll.jpg)

Dang Rich, it appears to be a ballistic clone.

I have not played with RL33 yet, but I've pretty well settled on US869 for top velocity and really good accuracy. My best accuracy load has been with 100 NBTs and H4831 though.

Very well might be. I had printed the post and saved it in my reloading notes. I have no memory of the source.
I hope I did not step on any toes, and sincerely apologize if I did.
