has anyone tried this? seems to me it should work. im thinking RL16 or H4350
why ? FOR WHAT ?
why shoot a "small" bullet in a big case ?
for mid to short range .there are several reasons that im going to play around with this and see what happens. just simply asking if anyone has any experience. but im very familiar with the catridge and running 200 - 230 grain bullets as i have ran them in 17lb light guns as well as 70lb heavies
Haven't had any 185 Juggs to try, but did test the 200-20x on the first 300WSM barrel. They shoot GREAT, ran RL16 62.7 gns, just under 3000 fps. It was like shooting a very big Dasher...
what is "mid to short range "??
I've done it. Very, very accurate but not the most slippery combination. Use 4350. The nodes are huge (almost 2 whole grains wide). I doubt there's a more forgiving load that a wsm shooting juggernauts
Thanks man ! What kind of groups did you look for at 300yds ?
It was an f class rifle, so I never chased the last 10 thou of a accuracy, but it was an easy quarter minute rifle at 300.
When I did a ladder test during load development it put 8 shots in sub 2 inches at 600 yards. Not a great achievement in itself, but those 8 shots were 4 different charges over a 1.5gr spread. I picked the middle charge in that spread and never shot another group with it.
Considering how easy it was to tune that bullet for a 308 I can just imagine how easy it would be with the powder charge in a bigger case.
+1 H-4350 worked great
I'm just the opposite, very familiar with 175 class bullets in a short action. Wicked accurate for a mid to shorter range.
4350 and the Jugg OTM would work . Might even suggest trying the 185 Hybrid . They do work better than the Jugg in some barrels . Touch bit harder to tune , but worth it when you get there . .005 off touch to start and move them out .005 at a time .
Might even take a look at the VV N-160 .
What sort of velocities are people achieving with 185's in a long barrelled F-class rifle?
The Juggernaut only has a BC of 0.284
I can push a 105hybrid (BC of 0.275) at a comfortable 3050fps its a great mid range F-open option, it is about as simple as it gets to make it shoot very small groups.
I have considered trying 200gr (either 200.20 or normal 200gr hybrids) for my 300WSM for midrange. But IMO, for F-open discipline at least, your selling the 300WSM short using anything under 200gr. The 215hybrid simply works so well in it!!
