LOADING QUESTION??

[74man]

If you are loading a certain cartridge and using a Barnes bullet or a Berry's bullet or extreme or whatever the maker is as long as it is the same weight and shape. Will any reloading site work for powder load as long as you are using the same bullet weight and shape. If you are loading Round Nose Bullets with a certain weight does it matter who the maker is for the loading data concerning the Powder Load? Can I use Hodgdon load data as concerning powder with a 155 or 165 or whatever weight hollow point bullet, flat nose bullet, round nose bullet as long as they are the same shape?

 

[AJC1]

Weight and material matter most and bearing surface can make a significant pressure difference as well

 

[Palladan44]

Treat a new bullet as a stranger and start at the published starting charge (for the same bullet, or one that is most similar) and work up.

Never take a new bullet and sub it out for a load that you worked up and assume it will be ok.

Technically speaking- ACJ1 nailed most of it. Hardness of the material, bearing surface and variances in diameter by 1 thousandth

Download and play with grt and see the impact of playing with each of the factors you listed. It costs nothing and may help you understand how each factor impacts pressure.

Both AJC1 and Palladan44 hit the overall highlights in there first post.

The material that they are made of and the bearing surfaces will determine pressures as well. My most loaded calibers are 25-06 & 270 Win. Between the two I have shot bullets from all major brands and a couple of custom makers.

What I have found with both, while not being scientifically measured were that the densities do matter. A solid copper, partition, or bonded core, type bullet usually gave me a high pressure signs quicker than a standard cup and core when loading same for same loads. With Berry's or other plated bullets your not going to be pushing for top end book listed loads or velocities. You will find they are simply not built for that type pressure.

Just as a for instance, loading a 115gr Partition for my 25-06, the standard load I use takes 55grs of powder A, switching to a Barnes X, the original ones, I topped out at 53grs, was hitting the same velocity, and starting to get an ever so slight ejector swipe on the case head. Going with a 117 Hornady flat base Spitzer, I can ease up to almost 57grs, before seeing those same signs and have exceeded the velocity I got with either. Going with the 117gr Hornady RN, I'm back down to around 54grs as a max due to the bearing surface and how much deeper they need to be seated to chamber.

As mentioned this is just a for example, but hopefully gets the idea seated. I just used my 25 as an example since I've been loading for it for over 40yrs, (dang that rifle is old), and could pull the best loads off the top on my head. As for the plated types through it, I've shot some of the Speer 120gr Gold Dot which according to Speer cannot be loaded to top end pressures and they sent me a specific load sheet for them. They can get close but top out about 200fps or so slower that the standard 120gr listed loads.

Just use due diligence in your selection of bullets for the intended use, choose a powder that is on the slower end of the data as those are usually more forgiving, consult several manuals cross referencing the powders, and work your load up for accuracy and you should be fine.

Here is a relatively recent thread that asked the same question: https://www.thehighroad.org/index.php?threads/do-i-have-this-right.906677/

Basically, no.

You can't treat a plated like a jacketed or 100% copper bullet, or a jacketed like a copper bullet, etc.

With plated bullets you can treat a same weight bullet mostly the same, or cup and core jacketed bullets of the same weight mostly the same. With 100% copper bullets you can treat same weight bullets mostly the same. Don't get lazy and careless choosing charge weights.

Have any specific examples you'd like feedback on?

Here are 3 of the 'same' bullets... all .30cal FMJ bullets, but if you look very closely, they are quite different. They are, for reference, L to R the Winchester, Prvi, Hornady.



The most obvious thing is the location of the cannelure on the Hornady bullet. That bullet, seated to the cannelure, vs the other bullets, would seat deeper and increase pressure. Further, looking at the Hornady bullet... the ogive is different. The Hornady bullet uses their 'secant' ogive, which is a much more slender profile. That bullet will have a further jump to the lands, for one thing, and will seat shallower than the others if no adjustment isn't made to the seat die. The Prvi is longer than the other 2... so if you are seating to OAL, that bullet will also seat deeper than the other two. They are also all different weights... 147, 145, and 150grn, respectively, if memory serves. The one thing going for them is they have the same basic construction and materials, but it's possible the jacket thickness differs, and certainly the bearing surface is different between the 3, given the ogive and base shape. ...and this is just between 3 of the 'same' bullet.

I believe OP is asking about 40S&W in 155/165 gr bullet weight and load data (OP correct me if I am wrong)

Berry's bullet or extreme ... same weight and shape ... Will any reloading site work for powder load as long as you are using the same bullet weight and shape

Can I use Hodgdon load data as concerning powder with a 155 or 165 or whatever weight hollow point bullet, flat nose bullet, round nose bullet as long as they are the same shape?

While Berry's plated is sized larger like lead bullet at .401" and X-Treme plated is sized .400", both have soft lead cores and I have used lead load data for both plated bullets with good results.

Yes, I would say you can use the same load data for Berry's or X-Treme plated bullets. Since 40S&W bullets are based on TCFP (Truncated Cone Flat Point), I also use same load data for Flat Nose/Round Shoulder/Truncated Cone Flat Point/Round Nose Flat Point.

But I do not use same load data between Hollow Point and Flat Point/Round Shoulder as HP load data tend to be lower due to deeper seated bullet base.

Hodgdon has load data for Berry's plated bullets - https://www.hodgdonreloading.com/reloading-data-center

• 40S&W 155 gr Hornady XTP HP CFE Pistol COL 1.125" Start 6.6 gr (1,103 fps) - Max 7.4 gr (1,219 fps)
• 40S&W 155 gr Berry's FP CFE Pistol COL 1.125" Start 7.2 gr (1,162 fps) - Max 7.8 gr (1,232 fps)

And X-Treme actually published their own limited plated load data listing one load per powder - https://www.xtremebullets.com/category-s/50195.htm

Wouldn't the same supply to 10mm.
