Problems finding load data

[slbdawg]

Why is it when I buy a powder or a box of bullets, I buy the ones that's hard to find data for? It started with cfe .223, I like the powder but a newer powder doesn't have an abundance of load data. I bought some 165 game kings and damn if it the powder I have (h4895) isn't really listed in the Sierra Manuel for that bullet for that grain. It's like I have either peanut butter or jelly. My mistake was buying bullets or powder (got what I could) before checking the Manuel. Also have some imr4320 which is listed, but haven't fallen in love yet.

By the way, this is really just me ranting about my own mess ups.

Are you sure there is not any data for H4895 and 165gr GK? Sometimes you have to reference several manuals to find a good starting point, I will say that bullet manufacturer data has always been the best for me. I just can't believe that Sierra does not have H4895 listed for that bullet. When I get home I will look at some of my books. What caliber is this for?

What caliber?

Although not the "proper method of searching load data... if you scour the various forums for the odd ball loads, you can typically find a "range" of what works for various people. Obviously it would be better to use published data, but when you become familiar with reloading you can kinda tell when something is not right along the process.

Worst case is you start lower.

Purely a hypo:

Say you have data for 150 grn, 170grn, but you need 165 data. You know that with a heavier bullet you will use less powder. You know that your data will be around the 170 data, but with a bit more powder. You might start at the recommended starting load for the 170 as your starting point.

Load and fire one round and make sure bullet cleared barrel... I have never had a bullet not leave the barrel by using this method. Accuracy has sucked on that low end and in certain semi-auto platforms, the low ends did not cycle reliably, but after all, its a starting load.

From my experience, published starting loads and published maximum loads are well within a safe zone for modern firearm applications. The starting load will give you enough juice to not worry about squib and the maximum load gives you some room for error (how much is dependent on caliber and weapon)

just my .2 cents. be safe

.308, listed for imr 4895 not h3895.

This should get you a starting point:

I have three manuals, sierra, lee, and hornady. I also printed off hodgdons data. I trust sierra loads for their bullets, and being I started reloading only a year ago, I'm trying to save myself time narrowing accurate loads. I figure if sierra recommends it, it must be close. I can load safely from other trustworthy data, but may spend more time finding a load i like. I do not trust replacing hornady bullet loads with sierra because of the pressure hornady usually commands. May be fine , but different bullets usually, different pressures. Plinking fmj's and such not withstanding. I do appreciate you guys help though, don't want to sound ungrateful.

Well I was going to post the link and data but I see WakeSS has beat me to it.

Sierra does list a load for 168 matchking, not a big difference in loads just glancing at them.
