30 BR at 1000y
- Thread starter LongRanger
- Start date
I am new here and noticed the thread. I am interested to see that the 30Br is considered unsuitable for 1000yd shooting.
I have seen 6BR shoot 7.5 inch 5 shot groups in 1000yd B/rest comp. A 6mm Ackley shoot 4.888 for 5 shots. and many 6mm Br and 6mm Dasher shoot similar groups.
Has anyone actually tried the 30Br at 1000yd ????

The 115gr projectiles i use have a BC of .366 same as the Nosler 125gr ballistic tips and i can launch them at 3200fps out of my 24" barrel they work fine at 400 yards so now i will try 500m, 550 Yards) and while i am at that range may get to try at longer ranges so will just see how far it will go before X Factor takes over.
Does anyone know what will happen will it tumble out of control off to one side or just tumble and loose velocity rapidly.
Again can anyone actually put their hand up and say yes i tried it and wouldn`t make it past 700 or 800 or XXXXXXX
Can someone who has easy access to a long range have a poke at it I won`t be able to try till at least 1st of May

Yes i understand it will be blown around as do all projectiles some more than others.
By may calculations if i launch a Nosler 125gr Ballistic tip at 3200Fps should be still doing over 1200fps at 1000 yards.
Anyway is all speculation till it is put into practice.
Just bugs me when people say it won`t work but they haven't tried.
I won`t be satisfied till i have at least had a go i hadn`t even shot at a target past 200m till a few weeks ago and 400yards with the wind pushing 8.5 inches was pretty easy and yes i know the further you get out the error multiplies but nothing ventured nothing gained.

Peter Short Memorial 500 metre Fly Shoot Townsville May 2004. Earl McConaghie shot a 30 BR on a Tikka Action with a Tobler barrell and 6-24 B & L scope to finish 6th in Light Gun. Not a great score but a result none the less.

Mannn! 4 pages of talk and conjecture and still no practical results to whet our curiosity.
As for BC differences, given equal potential accuracy of the rifle and load combinations, supersonic terminal velocity and NO WIND, will the .30 BC bullet not impact the target with group results that equal the .60 BC bullet? If so, would they not also impact with equal group results in windy conditions if both were shot by equally skilled wind-dopers?

Hi Dave..The 30 br 14 to 18 twist has been tried by three people at this range you quoted,Earls score of 132 is the best ..The next year when the conditions were not as nice the wheels fell off down to less than half of that ..As you well know this is a tough target that rewards when ya get it right and crucify's you on those other days..At the moment you are pretty well going to have to score about 50 per card to come out on top at this range and although you can still have fun trying to get the best out of this 30 br cartridge it certainly makes winning at lot harder ..JR..Jeff Rogers
Yes ..all true ... but the debate is about weather you can get a 30BR to shoot effectively at longer ranges. I dont know Earl personally nor have I seen him shoot, but the fact is a lot of the resulting scores in fly are down to wind and technique more than calibre.
Yes the bigger guns can make it easier ? or do they. I regularly see performance cartridges score below 243 and 22 based calibres. Thus it is, as always the 'nut behind the gun' which has the error rate.
I would be interested to see annie or Stuart Elliott, John Rawson, Matt Paroz, Dave Waters and co shooting this calibre.
I think we all would be suprised at the results.
The point of impact changes as a result of shooter error in most cases. And these guys can read conditions well.
Anyway its all speculation until its not.
Can' see any of the above trading their rifles in to prove my theory either.
I think the point is, if you want to be highly competitive you need a calibre which is forgiving. I dont think it is beyond the 30BR to shoot a good score but I dont think it would allow any margin for error either.
See ya at the range

Dave, i have been since 1995 listening to the theory that one day when the conditions are right those BRs are going get up and wop us all, well one thing i can bett ya if i ever get the chance to shoot in those super conditions in a comp then my gun will still be in front ..I know this because i don't concider myself a great marksman, i don't hold the great wind skills of some u mentioned,but my gun will be ready. I just pulled out my last 7 sets of match targets, added up the stats,it goes average for the score is a bit over 230 per match and average for group is 2.78 ins..If i were to put the same effort into a 30 br my guess would be 165 score and just shy of a 4ins group agg .. My take on this argument is that this represents something that i would not promote to any prospective newcomer.There are people out there that read this tripe we write and make judgments of what to build for the future and i'm one that would not like to see someone build a 30 br and be disappointed shootin the FLY match ..JR..Jeff Rogers......................

Jeff,
I agree with what you say in so far as I am comfortable my 300WinMag will probably shoot a little tighter than a 30BR in any condition let alone perfect conditions.
I will also agree that I would not recommend to a new shooter that a 30 BR is a competitive calibre at 500 m
but I would encourage anyone with any rifle 30 BR included to Come out and have a go.
After all most of us dont start with a perfect rig and as you would be aware the inaugaral Fly shoots at Canberra where predominatly with 100/200 yd rigs, F class 308's and quality varmit guns.
Haven't we come a long way from those days.
The guys who turn up and shoot with what they have, are hopefully the newcomers, who will watch us old coots and come back determined to kick butt, having learned from the experience and discovered a joy in the event.
I don't think we should ever discourage anyone from trying with a 30BR or a 220 swift for that matter. Its all about getting out and trying the event, if you enjoy yourself its worth it, if you win its a bonus.
Enough though, I guess we agree on the priciple.
Lets all shoot more and type less, cos "if your burnin powder, your havin fun."
Cheers
Dave
