Is anyone shooting the sst's or shockwaves sabotless in A 40 cal. I cant seem to get better than 1-3/4" groups with them using wool wad or without wads. If so what loading pressure are you having best results with

This gun has shot several other combos well using heavier bullets using different powders..

Answering your question about pressure...all the loads I tested were around 45K..I set this pressure as the upper limit for the remmage nut barrel. Pacnor .400/.408 with ASG gen2 ignition sytem... Zen

What is the fit like? Knurled? Wad? Though 35K has often been considered as an ideal pressure goal, and for 5744, 4759 and VV110, this wasn’t bad, for these slower powders, 45K seems like a practical goal, not only for good powder performance, but also still quite safe. HOW ABOUT THAT FOR A LONG, COMPLEX SENTENCE! Good info. Thank you.

Dunthat, When sizing the bullets, how loose or tight did you size the bullets? Did you use a wad and if so what kind?

Dunthat, When sizing the bullets, how loose or tight did you size the bullets? Did you use a wad and if so what kind? The SST's and Barnes needed to be knurled up to get a snug fit..just snug enough to stay on powder...the Fury's I had to size down to get the same snug fit...I found wool wads worked the best in all the loads I shot...I also found RL15 and Varget powder to be accurate with the Fury 225-250 ST bullets.

I felt this post deserved a sticky for now because of the load information being shared. As this board is not limited to one specific caliber it should reflect other calibers.

Here's the figures for 250 Fury ST...Varget powder The estimated PSI according to Quickloads was 44,572...the quickloads estimated fps was 2599 which was close to my chono results telling me that it accurate in my estimates.
The RL15 PSI was estimated at 44,689 This load proved to be the most accurate over several groups..
I consider these loads to be safe in my remmage nut barrel gun. Hope this helps...Zen

Dunhat, Great load data, nice load record sheets. The powder burn rate on those powder choices is some of the widest spreads on the chart I have looked at for a similar componet comparison. Do you notice much difference in felt recoil say between the h322 and the Varget loads?

I am shooting the 250 Fury ( FF ) in my 392/400 with a Fed 209A. I have used Varget, H322 and N530. All with a duplex using 4759. Velocity in the 2550 fps range.

Yep. I know some folks may not think it is a good idea. I'm reading modest pressure signs on the primer. It has proven to be very accurate with the 165gr CEB's,at 2800fps. I have a duplex load for 190gr XTP's.I have posted about it some time back
