Loads for H4227?
 

I have a barrel coming for a Savage, 1-8 twist, 16.5". So I would like to get some load data ready for when the barrel arrives, I have H110 and 220 SMK's but I would also like to shoot 125 grain BT's supersonic for varmints. I would like to find some loads for H4227 because it is an Extreme powder and I will use these loads anywhere from 15 to 80 degrees. Anybody have any starting loads?:bangin:
Thanks-Ron

Sorry..don't have any listed for H4227

Here is some software generated loads for 125 grain bullets:
All loads used: Remington 7-1/2 Primer
2400 From 15.0 grains to 16.3 grains
AA-2 From 3.8 grains to 4.8 grains
AA-5 From 5.5 grains to 12.6 grains
AA-7 From 6.1 grains to 14.5 grains
AA-9 From 12.3 grains to 16.2 grains
AA-1680 From 16.7 grains to 18.5 grains
AA-5744 From 16.2 grains to 18.0 grains
H-110 From 14.9 grains to 19.0 grains
N-110 From 13.7 grains to 17.7 grains
W-296 From 16.3 grains to 19.0 grains

Start all loads at beginning powder charge...bla.bla.bla
Use data and proceed with caution ...bla.bla.bla
All loads are untested by me..bla.bla.bla
You know all the precaution stuff

Quarterbore still has JD Jones info posted and 4227 data is towards the bottom.

Sorry you did say supersonic didn't you and thats subsonic with the 220s but you should have no problem going with a lighter bullet and working the load up to supersonic.

I have posted several loads for 180 and 147 gr bullets at:


http://reloadersnest.com/frontpage.asp?CaliberID=135

Here are the reloading data from the new Hornady manual for 130 gr bullets using IMR4227. I talked to one of the techs at Hodgdon and was told that IMR4227 and H4227 are the same powders and that Hodgdon is going to discontinue H4227 name and sell it under the IMR4227

Check out the Hodgdon website:

Here are the Hornady data:

IMR4227 vel(fps)
15.7 1600
16.7 1700
17.6 1800
18.1 1850
18.5 1900
19.0* 1950*

*Max load

Thanks a bunch for all the load information!

329pf, is the IMR version sold as an extreme powder or is it and just not advertised?

thanks again,
Ron

Imr4227 H4227?
 

crashnrondo,

I do not know. Try giveing Hodgdon a call.

320pf

I believe that IMR and H powders are made in the same factory....but have different burn rates...which tells me they are different. I believe that the IMR...formerly Dupont powder is an older formula and is not an extreme powder.

I know that H4350, H4064, H4198 are not the same as their IMR conterparts from personal experience....I have switched to almost all Hodgon powders personally all the way back from the Dupont and then from IMR.
