3. Some suggest dacron (spelling?) filler for reduced loads using handgun powders. Is there a rule of thumb as to how much to use?

I think the general rule is to use a filler when using powders...

I took a quick look at a 183 grain boolet, in a 308 Win, using QL and a 24-inch barrel.

With 25 grains RL-7, chamber pressure is approximately 19,800 psi. Muzzle pressure is approximately 4,610...

First of all, I want to thank everyone for the constructive feedback that I have received. This feedback is based on actual experience and is not taken lightly. If I ask questions, it is only to...

There have been two comments that questioned the boolit hardness of the rounds that I am using. I am not about to question the experiences of others. So there has to be something that I am missing....

At this point, I am just trying to develop a load for the SR-4756 powder that I picked up. I may have to check some other powders.

OK, thanks.

If you cast, NOE 460-350-RF

Not sure if you got the information that you were looking. I ran the powders and boolits through QuickLoad. To be clear, I am not recommending this loads. You should look at the projected chamber...

I have to agree. The SD is not really a factor at short ranges. However, the greater the target distance, the greater the potential effect of large SDs. The longer the time to the target the more...

Since I have an abundance of SR-4756 powder, I decided to see how it would function in 308 Win. I loaded rounds that varied in powder charge between 11.0 grains and 13.5 grains; varying each charge...

Thanks for the info.

I have searched the forums and this mold does not appear to be mentioned. I checked the Accurate website and do not see it listed. Does anyone have any information on this mold?

I ran a 218 gn RF boolit, with 6.0 gn RD, through QL; using a 6" barrel. Predicts 14,834 psi chamber pressure. 911 fps velocity.

Looks like a boolit in the 10-11 BNH range would suit your...

Thanks for the information everyone.

I think that would be great information to have available to us that would like to fine turn our rifles.

Based on the 50-yard data, I loaded 9.0 grain SR 4756 and 9.5 grain SR 4756 loads of 10 rounds each and tested them at 100 yards. Fired two 5-round groups of each load. The 9.0 grain loads averaged...

Results at 50 yards
I have generated data for SR 4756 loads ranging from 7.5 grains to 10.0 grains at a range of 50 yards. Some loads were tested with two 5-shot groups and others only one 5-shot...

May be of some benefit or it may not. I am currently loading SR 4756 in a 6.5 Carcano. I am using Wolf LPRs and have not had any indication of ignition problems of the SR 4756 with the large pistol...

I had 18 prepped 6.5 Carcano cases remaining from the last load testing. Decided to increase the SR 4756 loads and loaded 7.5 grain, 8.0 grain and 8.5 grain SR 4756 loads. Five rounds of each load...

Nice looking rifle. Hope it shoots well.

May find something useful here. https://castboolits.gunloads.com/showthread.php?460898-Load-for-my-New-To-Me-45-Govt-Springfield-Trapdoor

I want to use this rifle to shoot steel at 50 yards and 100 yards offhand. I think I have found a Red Dot load range that will allow me to do this. The battle sight POI is at the POA at 50 yards...

Yes, there is quite a bit of load data for both the 30-06 and 308 Win. I think I have enough data to work with on those two calibers. Now to find some data or correlation to the 6.5s.

I recently scored some SR 4756 powder. I did an Advanced Search to see what load data may be available on this site. Got about 41 pages that contain the "SR 4756" text. It took a while to go...

I guess that makes sense, since it is an Italian cartridge. Maybe produced by Prvi Partizan and stamped for their customer "NTW"? Not a bad price, $0.60 per round and primed. Vendor must have...
