It is/was special ammo for the L42A1 enfield.
155grain MATCH bullets, NOT standard NATO.

Ammo doesn't have a BC, only bullets. If it has a standard ogive any 155 gr will be roughly the same. Frankly, anything close in weight will be roughly the same.

In other words,you don't know and have no idea what I'm asking about.

I know exactly what you're asking, and offering my opinion. You asked what the BC of a cartridge is, there is no such thing. But you can approximate the BC of the bullet.

These are the BC's for the 155 Palma bullet:

155 grain Palma Bullet
0.450 Above 2600 fps
0.443 From 2200 to 1800 fps
0.417 Below 1800 fps

For a final answer I suggest emailing BAE RORG and asking them what the BC is. They have given a lot of the ammo away at NRA shoots in the UK. You could always get two chronos and calculate it exactly at your range for the given temperature.

Sure and Lapua Scenar GB491 HPBT 155 have a BC of .508, so all 155's are not created equal.

The RG 155's are designed for competition shooting, and to be more inline with the Palma rules. RG 155 is the only ammo permitted for the Canadian Cadet RPA fullbore rifles.
Come-ups for RG 155 is almost the same as 155 SMK or within 1 MOA. 1 MOA can be the difference in lot numbers and some lots of RG shoot better then others.

I never indicated all 155 are the same, but bullets of the same design, ogive etc will be very close. The scenar is likely a different ogive and design than the GS. The Scenar is HPBT first off.
 
Thanks Maynard,I'm afraid that Canam has never heard of the RG155 or its uses.Despite my very clear question,and yes of course i'm aware that it's just the bullet that has a BC,he continues to blather on about other bullets.Not a very impressive ad for the business.
 
I sent a fax to RORG. We'll see what they have to say on the matter. Sorry for trying to assist you with your question, how foolish of me. I suppose no good dead goes unpunished.

I'm sure you meant well,but lack of knowledge about the round in question really did little to answer my question.

From another forum :

99.9% of all Issued 7.62mm to the UK armed forces is made by Royal Ordnance (British Aerospace) Head stamped RG. (www.rgammunition.com)

It comes in three flavors: - 144 gr Ball, 146gr Sniper and 155gr Sniper/Target

The rounds are generally packed in 20 round cartons or 50 round trays. Then into 200 round packs or 400 round boxes.

Ball is indicated by a Black dot on the packaging, the sniper by a Green dot (or Green Spot as it is known) and the 155gr sniper is a Black dot, just to be confusing.

Velocity / Accuracy: -

Ball - 830m/s - 125mm horizontal and vertical deviation at 550M

Sniper - 845m/s - less than 76mm (3") at 500M

155gr Sniper - 845m/s (2775fps) 94% hit probability of a target 250mm (10") by 250mm (10") at 550M

So you felt it is OK to slag me for that? While I have not personally tested the ammunition, I was offering a solution to your query. Bullets of a similar design and weight will have similar BC. But the best way of checking BC is two chronos under your range conditions. Either way I should have an answer from RG on Monday. Maybe that will be of assistance to you.
 
Buddy, if it involves ammo, and CanAm doesn't know about it, its probalby not worth knowing.
Its not only his business, its his hobby also.
