I found this on the Hodgdon website:

http://www.hodgdon.com/data/youth/index.php

"For all cartridges we chose H4895 because it is the slowest burning propellant that ignites uniformly at reduced charges. For years, H4895 has been the top choice by cast bullet shooters. For this type shooting, loads are reduced even more than the hunting loads listed herein. To create loads of this type for target and plinking, we recommend our 60% rule with H4895. By taking the maximum charges listed in our Annual Manual with any given cartridge and multiplying it by 60%, the shooter can create a 1500 to 2100 fps load, depending on the bullet weight shown. This works only where H4895 is listed. Do not use H4895 in a cartridge where it has not been shown.

Call Hodgdon Powder Company if additional information is needed. Loads may be adjusted up or down to achieve best accuracy. Do not reduce by more than an additional 10%."


So if i'm reading this correctly i can take the hodgdon supplied reloading data for .30-06 and H4895 and go as low as 50% of the listed max?

I've used it with cast bullets in 30-06, 32 Win Spl, 45-70 and jacketed reduced loads in 257 Roberts, 270, and 30-06. I don't remember shooting groups with it but it worked well. I think 4895 is about the most versital rifle powder I've used.

Didn't you mean 60%

Not sure if I understand what you are trying to do here. Yes, you can reduce 4895 loads by 50% max. with cast bullets. I believe the 60% would get you closer to best (accurate) load. A 170~180 gr cast bullet with 30~32 gr. of 4895 worked better for my rifle.

If you have a lot of 4895 and want to use it, I can understand. But, if you are looking for an accurate cast bullet load in 30-06, you might try IMR-4198, (24.0grs.) or IMR-4227. (18.0grs) These loads produced best accuracy in several rifles.

For me, with a cast bullet of 165grs or higher, a good starting load would be 28.0 gr of any 4895 powder. this should avoid any problems with "erratic ignition".

Remember to tip the barrel up to settle the powder consistantly for the best accuracy with reduced loads.

Well here's my problem.

I've found a super accurate load for my 1903a3, but it's 3 grains below minimum charge. 43 grains of H4895 using a 150 gr hornady fmjbt in .30-06. All the load manuals I have show 46 as the start grains for this load. I'm just wondering if I should stop using this load. I'm sorta new to reloading and at the time i was experimenting i didn't realize that starting = absolute minimum you should go.

OK, now I see. ;)

Can't really help much here. My 30-06 loads with 150grs bullets are usually IMR 4064 loads. Only use 4895 in Garand loads.

I do know that Cast bullet loads go as low as 25 gr, of 4895. Kind of suprised that you're getting best accr'cy at that load density. Looked in all the old Manuals I have. (Phil Sharpe) Couldn't find any loads lower than 45.0.

Towney Whelan used to load 150 fmjs backward with a low-powered charge for "Grouse Loads", but couldn't find the data.

Don't think you'll get in trouble with your load, but!!

I will take a stab at this. Minimum (and maximum)loads are designed around the cartridge specifications.

Lets throw another into the mix. We all know that .308 brass has allot of variance when it comes to volume. I am sure that 30-06 is not far off. So the book says that 46Gr of h4895 gives 2806 FPS with a 150Gr bullet in a 30-06.

Now lets throw in the surplus powder mantra of "reduce all loads 10% and work up" 46Gr- 10%=41.4Gr.

I have seen some loads that are "less than starting" produce very good results @ 200-300 yards in allot of calibers. just understand that a load that is not "in spec" will not perform at 600 yards that the "full power" will.

IMO you are good to go.

There is a reason that HP shooters have a load for 200-300 and one for 600.

My 2 cents on the subject.

I don't think this will help you much but I looked up the reduced load I used for 172 gr. FMJBT.
It was 42.0 grs. 4895
CCI 200 primer
Win case
Mean Vel. 2355 fps
Std dev 24 fps

It was shot in a Win mod 70. Nothing special, not target accurate but fun to shoot, cheap, and easy on the shoulder.

The cast bullet load was
175 gr. fpgc bullet
34.0 grs. 4895
CCI 200 primer
Win case
Mean Vel. 1938 fps.
Std dev 40 fps
