Is there a program out ther that gives you the optimum powder to use in a rifle. I am wanting to try some hodgdon powder in a 270 win with a 22 inch barrel and 130g and 90g bullets. If someone has a program that figures this out could you run the numbers for me. Thanks
only the rifle can tell you what it likes,books,programs etc.. are only "suggestions" on what what might work for you.as far as the .270 goes-in my experience they arent that fickle as to what powder works[obviousy some will work better than others],just select a couple different powders for each bullet weight and let em fly-my-2-dave
I've been working on a program to calculate the ideal powder. This is what it shows for your requirement:
H-414 N-150 S-361
Aa-2700 W-760 Ar-2209 R-904
I-4350 H-4350 S-365 TU-7000
N-550 Aa-4350 N-204 Brg4351 RL-19 I-4831 Ar2213 H-450
Faster powders are listed first. Powders on the same line are essentially equivalent in speed but not energy. That means they don't use the same amount of powder to produce the same pressure.
The middle powders are best for the medium weight bullet, 130 gr. and the powders listed first are a little better for the lighter bullet, 110 gr.
Therefore, you are probably best off with H-4350 but can try H-414.
In the past I have had very good success with IMR-4350 and 4831. Used mostly 4350. With IMR now sold I though I would try some hodgdon powder. They list H1000, 4831, and 4350 as the top 3. I was wondering if the slower powder would all burn in a shorter barrel.
Here is my hunting buddy's load info for 270--he is consistant and an excellent shot:
Here are the 2 loads I use in my .270. They are max or beyond max in some manuals but I have a long chamber and I have no pressure problems and I have chronographed them too. My rifle likes near max loads. Work up as usual.
The later is my favorite and seems to almost always exit on deer. I have played with a wide variety of powders but have found no reason to use any other type now. CCI primers shoot okay but the Win primers give me a little lower SD and tighter groups (I have noticed this in other calibers also so I have switched).
