Hornady 62gr BTHP w/ canelure not in my Hornady reloading book. Just add some powder to 60gr recipe?

I’d use the 60gr data to start but I chrono my loads now. HDY online mixes the 62 in with the 60. Hodgdon online has some 62 gr data, it’s not for an HDY but perhaps your bullet is close. Good luck!

Hello guys & gals,

So I bought these 62grs here: https://www.midsouthshooterssupply....ameter-62-grain-bthp-with-cannelure-250-count

But the closest weights I have to these 62grs in my Hornady reloading book are 60gr or 68gr.

Should I just do some math & add a tad-bit of powder to the 60gr recipe???

Thank you all in advance for your responses,

Bull.

The 62 gr would take less powder for max pressure not more than the 60 gr. Heaver bullets need less to reach max pressure not more. It probably won't be much but you need to be going in the right direction.
 
Just so you know, with a heavier bullet you want to subtract powder, not add. It's not tit for tat with pressure. You add a couple extra grains of powder to a heavier bullet you also add more pressure. So if you want to use a heavier bullet you want to take powder charge away to keep the same pressure so to speak.

Your bullets are so close to the same weight I don't think it would matter much except that if the bullet weight is supposed to be 62 grain, its not unheard of for some of them to weigh even 2 grains more if they are bargain brand bullets.

Now you may be at 64 grains and that may add more pressure than you want if your already loading maximum loads. That's why you take powder away with heavier bullets.

If your loading lighter than maximum loads your probably still safe. You haven't told us what your load is so just wanted to point that out.
 
Because the 62gr bullet is a boat-tail, and the 60gr is a flat base, it balances out. The 62gr has less bore friction.

I’ve used both, and best load is same for both. I use 26.0gr of BLC2.

Even my Rem Mod-7 shoots it extremely well. Some even report good performance on medium game (deer). I seat to 2.250” so they fit my AR magazines.

At the moment, I'm using 17.4gr of IMR 4198 (Hornady book calls for 17.2). But I've never reloaded before, so I actually have 5 or 6 different powders & 3 or 4 different bullet design/weight combinations that I want to try. To see if there's a decent difference in accuracy.
 
The max load in the books is supposed to be never exceed. But some do. Start at the lower load and work up to max. Don’t just go right to an over max load. Maybe you did, I don’t know but be careful.
 
I have loaded over a thousand of that particular bullet, it is our favorite for use in rifles with at least a 1 in 9” twist rate. My all around Best load has been 24.5 gr of Ramshot TAC powder loaded to 2.25 inches COL. I haven’t noticed a significant difference in primers, having used CCI-400, CCI-450, RP 7 1/2, Federal AR match, S&B SR, and Wolf 223. The load is mild enough that CCI-400 primers work fine and yet still shoots flat enough to ring steel out to 500 yards. Other powders that work well With the Hornady 62 gr BTHP include IMR-8208XBR and Benchmark. I was glad to see them back in stock at Mid-South Shooters Supply.

This worries me. It's either a typo or a very fundamental misunderstanding of reloading.

A heavier bullet permits less powder, all else being equal. This is important.

Use the data for 60gr bullets, and work up from starting loads.
 
Hodgdon's online data doe's show a 69gr Sierra HPBT (hollow point boat tail) using the powder you mentioned. You might want to take a look.

No need to worry, I understand, now, that heavier bullets requires less powder, not more. I was thinking the heavier weight of the bullet would need more powder to give it more "oomph." But it makes sense to me that the focus is pressure, not powder.

Plus, I wouldn't have loaded without doing my research. Including looking in the Hornady book, & realizing that 60gr bullets require less powder than 55grs lol.
