Re: N110 supersonic load data Anyone?

Hello to everybody, my name is Diego, from Spain ,I´m new at this forum and in my city only find N110 powder, It´s har find information for this powder and for it I want help as I can. I purchase some 125gr ppu bullets, FMJ and HPBT, I send an Email to privipartizan and they answer me this:

We can give to you reloading data only in form of INFORMATION, not OFFICIAL RELOADING DATA.

For A-636 ( 300 AAC Blackout FMJ 125 gr ):

Maximum cartridge length is 52 mm. (2,04724")
Maximum bullet length is 24 mm. (0,944882")
Length of case is near 34,72 mm. (1,3669291")
Length of barrel for which we do ballistic calculation is 406,4 mm (16") and this length is official given duo to SAAMI standard for centerfire carbine and pisotl ammo.
With Vihtavouri N110 powder and 100 % filling case with this powder you will have muzzle velocity around 618 m/s (2027,56 fps), chamber pressure around 2731 bar ( allowed is 3792 bar duo to SAAMI standard ).
Powder charge is 1.019 g. (15,72 gr)

For A-638 ( 300 AAC Blackout HP BT 125 gr ):

Maximum cartridge length is 53,3 mm. (2,098425")
Maximum bullet length is 26,2 mm. (1,031496")
Length of case is near 34,72 mm. (1,3669291")
Length of barrel for which we do ballistic calculation is 406,4 mm (16") and this length is official given duo to SAAMI standard for centerfire carbine and pisotl ammo.
With Vihtavouri N110 powder and 100 % filling case with this powder you will have muzzle velocity around 605 m/s (1984,91 fps), chamber pressure around 2616 bar ( allowed is 3792 bar duo to SAAMI standard ).
Powder charge is 0.981 g. (15,14 gr)

All powder charges above 1.019 g or 0.981 g will give compression which is not good.
Also Vihtavouri N110 with barrel length of 406,4 mm (16")cant give velocity above 620 m/s.

For example our PPU ammo,factory load, have a muzzle velocity around 690 m/s (2034,12 fps) with WC 297 powder.

I put between bracket () the translation from mm and m/s to inches and fps, I think will be easy to read for everybody, and I hope do rigth the traslation!

I reload some rounds 14,0gr to 15,5gr (OAL 2,038" to 2,047") for 125gr FMJ and 13,5gr to 15,0gr (OAL 2,090" to 2,098") for 125gr HPBT, but I can´t go shotting and measure velocity yet. People from privi tells me are safe loads.

I hope somebody can find usefull that data.

Best regards.

Diego.

Here is a whole thread on it.

VV N110 is not a bad powder to be stuck with...

Thanks for the link Dr. Phil, I know (read this forum is so usefull) 110/125 gr are best bullets, but 147gr/ M80 bullets are cheap for reloading though maybe not the most accurate. I found a lot of load data for 110 and 125gr of many manufactures, but for 147gr I don´t find so much.
Anyway, thank you very much for your interest and help! :)

Vihtavouri and Hornady both will have data for N110 and 150 grain bullets. 147 grain is harder to find.

This will get you started.

300 Blackout, not just for sub-sonics.
