Believe it or not- I still have some 100 Gr BT's left. Many of you know that I have been loading for a model 99 1:!4 twist so I picked up some 87gr Speers. Works fine in the 99. One of the loads that Speer lists for both 87 and 100 Gr Speer Hot Cores lists CFE223. Unfortunately, Nosler manual dosent list CFE 223 in a load for the 250 Savage. Is there a safe way to use CFE 223 and a Nosler bullet? I can find CFE but not H 4350 or N150, so would like to use the CFE since the velocity #'s with speers look really good. If quick load will have the answer that would be ok. Remington Brass, CCI 200 primers. Thanks CL
 
Hodgdon shows cfe with a 100gr hornady, you could probably look at the other powders they list that nosler also lists and have a good idea. If i was at a computer vs my phone I'd look closer for you

the Nosler Ballistic tip , is shaped similar to the old style bullets . I would say you could use Hornady , sierra , speer info without any problems . don't use info for the long sleek shaped VLD style bullets . as always start at the minimum charge and work up , while watching for pressure .
 
I always advise against in using other bullets data that are close to bullet weight I can't find data for.

#1 too many intangibles...bearing surfaces can't be conpared unless you've a 20,000 dollar machinist real comparator to measure both bullet's bearing surface.
#2 some bullets are softer than others even though both share a similar jacket.
In other words one could be more slick while cutting through the rifling. Again something impossible to know without equipment I doubt you have.
#3 is your rifle
Every rifle is different so that intangible always makes for possible differences.

Dr. Mike always comes through posting a quick load for us.
He's a wonderful fellow poster always offering up data and his time.

Good luck

While Lee reloading manuals do list data based solely on weight, the metallurgy and bearing surface should never be ignored. All attempts to simply rely on weight should be approached with caution.
 
I've always swapped data back and forth with identical weights in C&C bullets. If it's a powder and cartridge combination I don't have a lot of experience with, I start at starting charges and work up watching for pressure like Jim stated. Long bullets or big differences in metal makeup such as a Swift A-frame etc, are not bullets you can swap with standard C&C.

If it's something I'm a lot more familiar with like a 30-06 and a 150 gr bullet with IMR 4064 it's always gonna end up somewhere around 52 gr's in my experience, and with a new gun I will load 1 at 51 & 1 at 51.5 making sure I'm alright on pressure and then go right to testing at 52 gr's. It doesn't matter if that bullet is a sierra, hornady, speer, nosler BT, or if it's a flat based or boat tailed version. It may or may not shoot that particular bullet well, but it wont be dangerously overpressure even thought that load is top.

I don't start out at max, but swapping C&C data I've never once in all my loadings of different rifles had a bolt that was even difficult to open let alone had to be beat open like I hear some guys talk about. Everybody has to know what works for them, but I have zero qualms about swapping C&C bullet data if you use your head.
 
I did some looking in my books . I doubt I have a book new enough to have CFE223 in it .

quickload shows the Hornady , sierra , speer , bullets maxing out about 1.0 - 1.5 grain more powder than the nosler . keep in mind , not all guns will be able to use a book max load . most of us only need a general starting point , and we can figure it out from there .

most reloading problems can be avoided by following the rule , " start low and work up while watching for pressure ".
 
One would be surprised how many shooter’s pressure problems are because they started 1or2 grains from max and locked their bolt. There is a reason reloading manuals list a starting load.
This- I wouldn't be surprised anymore. Couple that with a scale error and I did it to myself.. (See my post about "failure to trim". ) Thanks all for sharing your insights. Hope some one else can learn too. Interestingly, Dr Mikes quickload (Thanks Mike) shows noticeably lower velocities with Nosler bullets than the 100 Gr bullet load listed in the Speer Manual. Interesting....CL
