Solid brass bullets - Want to know

[Jose_Luis_G]

Hi guys,
I have designed a very nice (to me) solid brass bullet in .30 but need to know if this kind of stuff is allowed in F-Class competitions.These are made in a CNC lathe and, despite they are rather expensive, I believe that they are the top-of-the-best in performance.
They combine the geometry of a regular 220 grain, but with 170 grain weight.
Please let me know about the official normative on this matter.

Do you know if these would stabilize in a 1-10" twist?

For sure it would!

For sure it would!

I wouldn't count on it. Over the years the 1000 yard BR guys have shot these bullets made from all different makers and nobody got them to be competitive. In fact I haven't seen any get even close. Guys even tried faster twist barrels and bore rider throats. Matt

Hows brass on your barrel over copper?
What ive found is when you have to use a faster twist due to length and the weight isnt there throws everything off. Lots of lead free stuff going on right now. I cant see why they wouldnt be legal and i know their use will be encouraged by your fellow competitors

Isn't this quite similar to Dan's "FlatLine" that he's developed at WTC? Lathe turned chunk of brass? at a very high BC but with a corresponding lower weight? I do believe they have finished testing and might be available now? Eric in DL

It may happen that a faster twist is not the right way.
Most people is confused about that, in the way that they use faster twist for lighter bullets.

In my opinion it is not the weight what determines the twist, but the geometry of the bullet.
Going on with my opinión, this one should be considered as a 220 grain -twist wise-, even when it is a 170 grain.
A 1:10 twist should be fair good for it.
The most important point for this kind of bullets is the diameter, which must be deeply calculated for each and every bore before starting mass production.

Anyway, my question was different.
Do you guys know it this type of solid brass bullet is acepted for competition or not?
Forget about accuracy, that is not the point today.

I wouldn't send one down my barrels!

I haven't asked you for it.
Please give an answer to my original question if you can.

That sounds reasonable, but you know that rules are there to be fulfilled.
More if you start shooting better that the rest and they find out that it is due to the solid brass bullets.
Many people would start digging into the normative to kick you out of the way.
Nobody likes to feel the breath on the nape.

For sure it would!

How much for 50?

Hi Dusty, Grab a 5/16 hunk of brass barstock and bite on it ......now take a barts and bite on it ........I shot next to a guy in the worlds who was using solids, 3rd relay barrel was shot
If solids worked in F-Class all my CNC lathes would be running 36 hrs a day...

ICFRA (F2.20) explicitly states that monolithic bullets are not approved. If your not shooting under ICFRA rules you'll have to look at the rules of that governing body.

Exactly

Sorry, I do not sell them. I'm just asking for the legality in competition.
For your information, these are not produced but in bulk, with a min 5,000 units by batch, and the price for it can go up to 7,000 euro.

I agree with you in the basics, but there are many alloys of brass.
Most important than that is the fact of the diameter of the bullet. That is the basic question in all the design.
Diameter must be personalized to every and each barrel, one by one.
Not so easy.
You are also forgetting that brass coats have been already widely used in cartridges like Vetterli Vitali or 43 Spanish (1870) without making any damage to the barrels.
But the point is that finally, I have read that they are not allowed in competition here in Europe.

There's actually some history to solid core bullets. There was a guy in Oregon making solid copper bullets. There's a reference to them in Zediker's handloading book. Problem is, who wants to spend $1 per bullet?

 

[Joe Salt]

To answer you question, some clubs do have rules about Armour piercing, incendiary, and explosive projectiles. Other than that you good to go!

Monolithic bullets are allowed in competition, in the US. I do not know if they are allowed in Europe.

However, you should verify with the range administrators that the specific range will allow them.
