Lapua Scenar L loading advice.

[std7mag]

I have run accross some sales on the 7mm, 150gr. Lapua Senar L.
Was thinking of these for several of my rifles when shooting longer distances (600-1,000 yards) for target practice, and possibly an F-Open match.

Any experience with distance from lands they prefer?
I've lately been shooting Berger VLDs and for my rifles they prefer right up next to the lands (best groupings 0.005"-0.010" off the lands).

I should have no problems with my Rem Mag or 280 Rems. But my 284 Win has a long freebore (leade, throat, jump, whatever you want to call it). Meaning the Berger VLD does not shoot well from this rifle.

Thank You

I'm shooting the 136L in my 6.5 creedmoor.
I'm forced to load at magazine length and shoot from magazine. I'm jumping .060.
For a production bullet I really like them.

I haven’t tried the 7mm 150gn, but have shot a lot of the 180’s. Also the 123 and 136 in 6.5mm. All of them worked good for me at .010 jump.

Std,7mag,

I have tried the Scenar 150 L in my 7mmO8 ,Border barrel 1/8.5 at 2760 f/s .003 off . The accuracy was fantastic with some group Under .1Moa
at 100 yds !

Would you mind sharing your loading data

It was with N 140 , Lapua Palma 308 , neck down to 7mm(neck turning),CCI 450 primers.

Ok, so like any typical VLD, play with seating depth. Gotcha!

This bullet is nothing like a VLD - it's a traditional tangent ogive, relatively short nose (9.75 calibres radius), RtR value 0.83, design. As a result, it's very jump tolerant. I've used it for short-range in a 7-08 F-Class rifle for several years, set it at my usual starting-out-in-load-development 15 thou' jump for this type and never changed it or remeasured it, now some 1,600 rounds plus worth of throat erosion. It still gives near benchrest 5-round groups at 100. Like all the Scenar Ls, production quality / consistency is very good indeed. In fact, overall it's well designed, well made, very workmanlike, but very much a mid-level player in its ballistics in a world now full of superstars.

With a 0.991 'form factor', it outperforms many of the older sevens, but is relatively high drag when compared to equivalent recent match bullet introductions which are down in the low to mid 0.9s, some even down in the high 0.8s. Allied to 150gn weight, light these days for a match seven, it's a relatively short-distance model with a resulting 0.268 BC and therefore lower than what have become run of the mill 185gn 308s used at similar MVs in 308 in competition rifles. (The now 'oldish-hat' 185gn 0.308" Berger Juggernaut has 0.283 G7 BC.) A good seven using today's 180 and heavier bullets (180gn 0.284 Berger Hybrid 0.345 G7 BC) will wipe the floor with the 150 even in short/mid range use. This eventually happened to me - I used to use this bullet in 300 yard matches relying on its inherent precision, but with any real variability in the wind, just about everything else on the firing line including 308 F/TR rifles now shoots 'inside' me so heavier and higher BC designs have had to be used even at this distance.

Stellar results with 0.020" jump but that is with the 180gn L. Try it with your 150's.

My use would be primarily informal target practice with several hunting rifles.
Aside from a custom built Mauser in 284 Win that ended up way too heavy to use for hunting.
The bad with using it for a range rifle is a really long freebore. Making use of the Berger VLD unsuitable. It does shoot the 154gr SST, and 150gr ELDX and ABLR well.

Question....What powder at how many grains are you loading to? ThX

 

[wwbrown]

I have found them to be very insensitive to jump distance, like Laurie said, I have loaded them in 6 mm, 6.5 mm, 7 mm, and 338 all were jump insensitive.

Depends on cartridge

The 123 gr. Lapua Scenar L is really accurate @100 yds. in both my 260AIs @ .020 off the lands. Almost as accurate as the 140 gr. Berger L R Target

Thx Bill.
