SARA Queens and Hunt results

[Lynn Otto]

I must corect Lyn , I used a Barnard smithed by PSECO with a Lilja 30cal barrel chambered in 300wsm and using 220gn Sierra MK's, not to worry Lyn it's still a dirty 30.

Ah sorry Paul, but please don't shoot the messenger, I was but the humble relayer of said information, I'll point out the error to Trev.

I think I started that

What is it about hosting a queens that seems to bring out the big winds. I,m not religious, but I think the big fella up stairs must be anti gun, or just have a warped sense of humour. How many times have you heard it said, jeeze, this was the biggest winds this year, right when the queens happens to be on.
Congrats to the winners, those who just had fun and everyone in between.

Paul,

Doesn't the newer 210gn SMK have a higher BC? It seems to be the one the match rifle fellas prefer.

I've always used the 210 Berger or SMK in preference to the 220 purely on the basis that they travel maybe 10 MOA lower out to 1200 yards. I figure that the lower they shoot, the less possibility they have to get into the shotty wind you can't see which by Murphey's 8th commandment, will always be worse than the stuff you can see.

It probably didn't help that when I did by necessity shoot the 220s in Campbell Town in 2003, I had neuralgia from my cheeckbone to my hip for a month afterward. These days, I'm in the column of the wimps when punishment is offered.

Its called Adelaide in the springtime....always windy here this time of year

Hi Alan

Yes the 210 SMK has a higher BC, but it also shreds it as the velocity drops a lot faster and ends up a lot lower than the 220gn at the longs.

I am going to work up a load with the 200gn SMK for ranges out to 500 meters then I will switch back to the 220 grainers. The 200gn SMK's also hold onto there BC as there velocity drops.

Ken Melgard asked me why I was using such a heavy bullet, I dont think I gave him much of a diferent answer, but he also said/ sugested to me to try a faster bullet. So I thought to myself on the way home from the Queens, why not use the 200gn SMK's as I still have heaps from my 30x284

I have just switched from shooting right hand , left eye, to total left hand shooting. I did have a few isues to come to grips with, but now I am confident in the way I shoot.
My Barnard is a right hand action (right port) and I feel it is easier to shoot seeing where the empty is to come from and where to put the loaded round , Just my idea.

I've done some calculations out to 1000yds with some of the long SMKs using the BCs from Sierra's website. The Sierra BCs vary with velocity so I have included that in my calcs. I have assumed muzzle velocities for your 300WSM as per the chart after looking at some reloading data from various sources on the web.



The 210 and 240gn are newer, and as you'd expect, perform better.

So what you might be doing by moving from the 220gn to the 200gn is going from the 2nd worst to the worst performer! Of course BC isn't everything - some swear by flat base projectiles at the longs, saying they are more accurate, and that is what really matters.

Alan

[RDavies]

Maybe the 200 gn pills move the velocity into the accurate velocity barrel node ,around 2920-2950 fps, making up for any extra BC?

[AlanF]

Quite possibly Rod. Part of the equation is how much you're prepared to back your wind-reading skills - you can sacrifice BC for accuracy then make up for it with skill in combatting the bullet getting blown around more.

Are you still hoping to get to Canberra? If you and a few other NSW shooters are there I'd like to talk about the F-Open Teams event at Bendigo in March. SA are intending to send a team, so would be great if NSW can muster one up as well.

Hi Alan and Rod.

Alan , thank you for the comparison chart, the 210 MKs look like a good preformer.
I was hoping to push the 200 MKs faster and just use them to 500yards/ meters.
I also have a supply of 240MKs, but the 210gn MKs look impresive, figure wise.

Iam getting 2,850 fps with the 220gn MK's, I was hoping th get into the 3,000 fps with the 200gn MK's.

A few people keep on at me about trying Berger 210gn pills , when I run out of my stock I may try the Bergers if there is a good supply like the Sierra MK's.

Cheers
Paul
