Im going to be getting a TRG-42 in .338 lapua magnum soon, and i was wondering, what would be an average grouping with this round for a semi experienced shooter at 1500yds using 250gr black hills ammunition? I do not hand load so i will probobly be using Black hills ammunition, but may get into hand loading later.also, does anyone know of a better
manufactured 338 lapua round?
thanks

lots of factors
every rifle likes diffenrt ammo better than others so not all TRG-42s would like the same ammo even
then how well can you shoot?
not at 100y, at long range, 100y is point and pull the trigger, at 1500y its a completely diffenrt game
most shooters i know would be lucky to hit the broadside of a barn at 1500y

Lapua itself (i think) makes a very good factory round (they improved it so why not) i could be wrong though

Yes, at long range (1500y) the weather and atmosphere have the biggest effect on the groups. In theory, if the rifle shoots .5 MOA at 100 yards, it'll shoot .5 MOA at 1500y (which would be a 7.5" group, which is probably darn near a world record). At those ranges, even the slightest breeze plays havoc. So, to answer your question, I would have to change it to say the rifle will probably shoot .5 MOA at 100y with Lapua or BH ammo, but there are no guarantees, and at longer ranges, you are at the mercy of the weather and your shooting ability.

worlds record is sub 5" @ 1536y with a .408 Chey Tac for a 5 shot group
last i herd this was the record but it coulda been broken but thats damn impressive
i have tried and do a little bit of long range shooting whenever i can get a hold of a rifle capable of it, i have tried 1 mile and i can tell you mel is correct, you are at the mercy of the weather and your ability to judge how many clicks you need and all... then you have to actually see the target, i dont have that problem but many shooters i know do, this depends on the scope you get and how well you can see

 

[mele]

Yep, so the world record 1500y group is .33 MOA. I shoot sub .25 MOA at a 100y/m all day with my bravo-51. Just goes to show HOW hard it is at extreme ranges....

another thing which could hurt accuracy at longer ranges
say 1 round fires a 300 gr SMK @ 2850 fps and has a BC of .768 and the other goes at 2835 fps, 15 fps difference between the two...
that should be 1/2 MOA differene in elevation right there, then factor in 1/4 MOA for what you and your rifle is naturally off by or you are naturally off by if you are an accomplished shooter...

so what if you mis-judge wind by as little as 1 mph... 13" drift... almost MOA right there

and its not just wind at your location, its wind at your location, wind where the target is... yep the wind will blow differntly 1500y away... and the wind inbetween you and the target!!!

mel says on the ammo page that realistically the average sniper could shoot about 1200m with it... now these are snipers who are trained in long range marksmanship
1 mile is pushing it under the right conditions and the right shooter of course

hey guys,
I gues there is no real way to estimate a certian grouping, Well, just because i would like to know, if we brought the range down to maybe 600yds, what could an average person who shoots often group at this range group with factory ammo? I think maybe this range could be estimated for grouping.
and jeff actually mel wrote "The effective range of this caliber is about 1 mile (1600meters) and in the right shooting conditions, it could come very close to the 2000 meter mark, provided you have the right rifle/ammo/optics/shooter/spotter combination. Realistically, 1200 meters is well within the average sniper"
Thats a little different than the way you worded it. I think its more like in the right conditions and equipment an experianced sniper could effectivly hit his target at this range. But for the average sniper 1200meters would be quite an easy shot. and remember you thinking of meters and i said yards 1500yds=1371m

thanks for the replys

yes i know what i said
1200m is NOT an easy shot for the average sniper, less difficult than a 1600m shot but still by now means easy.... some snipers might make it look easy though, still not... one skrewup and its a miss
that means no loosing concentration, no bad trigger squeeze, no incorrect ajustments, no margain for error there for windage or elevation, very little margain for error in range estimation
2000m is going to be quite the difficult shot and is really gonna be pushing it
look to the maximum effective ranges on the rifles, byond 1100m for the Sako and AI, Dakota being capable of 1400m shots... the only one ive fired was the Dakota T-76 Longbow Tactical and its definitely one of the greatest rifles money can buy and id expect the Sako and AI to be right up along side the Dakota

i have shot 3" groups @ 800y with my Remington 700P in .308 with my Leupold Mk4 PR 3-9x40mm scope, prone w/ bi-pod in excellent conditions

all this talk makes me want to go shoot my uncle's T-76 Longbow tactical again dammit then i could tell you the average group size of a world class .338 rifle for sure

Some points that need to be made:

When I say an average sniper, that means someone who has gone through formal military training (not just the civlian schools) The average sniper is an exceptional marksmen when compared to the typical shooter. An average sniper has gone through extensive professional training. A 1200 meter shot is extremely hard with ANY caliber/rifle combo, but it IS within the capability of a average trained sniper with a .338 Lapua
