35 Wheelen with 173gr FNGC
« on: November 26, 2006, 02:27:39 PM »
Good day at the range - 4th trip.  First 3 I was trying 4227.

Eight 4-shot groups with 4350 at 50 yards.
Seated into the rifling (sometimes tough to close bolt) and lightly crimped into bottom lube groove.
No filler - case was 80-90% full
Gas checked, sized to .360 dia.
All grooves filled

The bullets are hard cast, air cooled. Fingernail doesn't make a mark on it.

45 gr - 3 shots in .50" all 4 in 1.02
46 gr - all 4 in 0.90"
47 gr - all 4 in 1.24"
48 gr - 3 in .52 all 4 in 1.08
49 gr - 3 in .63 all 4 in 0.81
50 gr - 3 in .53 all 4 in 1.64
51 gr - 4 in 2.32"
52 gr - 4 in 1.63"

Often it was the first 3 touching and the 4th outlying.

Rem 700 Classic with 1:16 twist.

Which mould are you using?  I've tried Lyman's 358627 (nominal 215 grain, GC, SWC - is 220 grains with my alloy) with outstanding results.  In fact, the 358627 is the most accurate 35 mould I have in my rifle - and I have a bunch 35 caliber rifle moulds, as well as even more 35 pistol moulds.

My rifle sounds the same as yours - 1:16 twist, Remington classic 35 Whelen.

THanks for the post!  I'll keep my eyes open for a 358627.

THe mould is one of the 6 cavity group-buy Lee moulds from a year or so ago on Cast Boolets.

Next go-around I'll go with a heavier bullet 200-250 gr range.  (the 358009 couldn't keep in on 8-1/2x11 at 50 yards).

I've got a bit over 200 rounds of brass to process before then next set of loads, will anneal the cases this time too.

That 358009, is that the 280 grain bullet?

I've read several people have not had success with that in the Remington Whelens due to the 1:16" rifling pitch.  I wonder if it couldn't be driven at closer to full-house loads an if you could get better accuracy.

After some time playing with cast bullets, I've become a bit skeptical about the velocity limitations often bantered about.  Indeed, if you push a cast bullet too hard it will strip.  But I don't think it's as simple as assigning a muzzle velocity as the limiting factor. 

There are other factors that seem to play in.  Bearing surface seems to be one, in my experience.  Acceleration force is another.  Shooting a heavy-for-caliber bullet maximizes the bearing surface.  So a heavy 280 grain bullet should be able to tolerate a bit more force than a short 180 grain bullet. 

Also, so often the cast bullet loads seem to use fast powders, even pistol powders.  In theory, you should be able to get a cast bullet up to 3000 fps with no problems IF you have a slow acceleration and IF you have a long enough barrel to do it in.  My Adams & Benet barrel with a 1:14" twist will stabilize a 280 grain bullet at 2250 fps, probably even slower (that's actually the slowest I've shot it at).  I'm shooting a paper patched bullet.  One powder I use to get this is RL-19 which is slow for a Whelen.

Yes.  I think (from what I've read) the limiting factor is pressure.  THat correlates with slow powders, smooth acceleration etc.

I've got 250 and 300 gr J bullets (as well as .375H&H and .458WM) if I want to go max effect and shoulder abuse.

So with this one, I'm inching up in weight, keeping velocity moderate, to get the largest soft bullet I can launch - great effect & comfortable to shoot.

Sized and cleaned all the brass.  More loads after a bit, working on .308W cast at the moment.
