View Full Version : I want a educated guess on my educated guess

So here's the story, I got this NOE whisper 247 FN that I want to use in my '06. I want to make some heavy loads with them. I found some data for a 250 gr jacketed bullet in my modern reloading 2nd edition with H1000(55-58gr) and h4350(45-47.5 gr). What I intend to do is cut the starting load by 10% and work from there. Does that sound totally crazy to you? Should I gho back and rethink my plan or would you assume this to be safe enough to try.

Any input would be much appreciated.

Thanks for your time.

I'm currently doing it with the 357 mag. LEE 140 gr SWC and Unique.

If you can get the MODERN RELOADING By RICHARD LEE, in there he has a formula for using powders at reduced loads. I have no clue what volume/edition (Red hard bound book) I have but I've used the formula for cast and it does work. In my book it's on page 88-94, which may not do you any good.

it's safe enough.
on target results will be the deciding factor.
cutting the h-1000 back will leave you a pretty dirty bbl.

I actually got it. I got my load data off of it. Only thing is they usually give you a factor with which to calculate the theoretical reduction in pressure and velocity for 1 grain change in pwder load. Yet it's not available for everyload in the book, which it incidently isn't for the loads I'm interested in. Thanks for the heads up though.

Runfiverun, Rgr that on dirty bbl. My main concern was that I was heading in the wrong direction with my plan. Kind of just reassuring me of my logic, hence the "educated guess on my educated guess" part. It's just that no one else I know of plays with reduced loads around here. All they seem to care for are ultrafast, bigbore ultra-super-dupper magnums. I even had one guy wanting to shoot a deer with a, IIRC, 458 win mag(?). I asked him if what he was looking to do was kill AND process it in the same step. Y'know, shoot it and then you only have to put the ground meat in bags and freeze it :holysheep

N'way, enough with my ranting, thanks for the input guys. As always you proove very ressourceful.

I use this boolit in my 30-06 with 35gr of H4895, 3 rounds in a clover leaf at 100, 1950fps and bore is spotless.

Typically powders that burn faster for a given application will be more suitable for reducing loads than the slower powders. Hence I'd think H-4350 may be the better of the two powders for your application. You also might want to switch to a magnum primer for reduced loads just to make sure you get good solid ignition of the powder.

Well, I went out and shot these tonight. Had a couple of max-20% of H1000 and H4350 loaded. Let's just say results were below expectations. I somewhat expected poor accy, but out of 10 shots I had 3 on a 9.5x11 sheet of paper at 100m :holysheep. Just for the record, I had no indication of heavy barrel fouling with the H1000. No unburnt powder, but it made a big *** ball of flame and a TON of smoke. Even though I didn't hit paper, I had fun just from that. :p

I guess it's back to the drawing boad with these. I'm thinking I try to push 'em way to hard. Next, I'll try some light h4895 loads and see if it get's any better. No real prob, still got 2 months to work a acceptable load for these.

try for 1900 fps.
28-30 grs of 4895 and a filler for ignition consistency.

Got it shooting. 25gn H4895, no filler. 5 shots touching at 50m, within 1 inch at 100 m. Best boolits I have by far!

excellent you can try walking the load up now that you have a baseline.
quite often groups will get bigger then smaller again.
