30BR Short & Long Range

Well here is the short and long of it.
On the Saturday afternoon 29th of April at our local range we had a center fire Bench-rest shoot.
As there was only my 30BR and 6X6mmPPC`s they decided on a score match with three targets at 100 yards and another 3 at 200 yards and a group target thrown in at each distance just to make it different.
Well to cut a long story short i beat them in the score shooting, their excuse being my holes were much bigger hahaha but to rub salt into the wounds i beat them at the group as well.
With a .197 at 100 yards and a .232 at 200 yards.will attach photo`s.

Reloaded that night and the next morning the mate and I drove 250 miles north to Townsville for a 500m Fly shoot,550yards).
Having not shot 500m before we weren't too sure how we would fair.
We arrived in time to get a few sighters in on the Sunday afternoon and within 5 shoot had 2 in the ten ring.
After raining all night it cleared the next day to overcast Sky's and a westerly wind which had everyone guessing.
Well for a pair of first timers we did OK biggest problem which we still haven't figured out is after putting down our sighter shots on the sighter target we would wind the windage top of the front rest across to the score target, they were about 3 feet apart on the frame at 550 yards)the first shot on the score target would go 6 or seven inches right now right was into the wind now if we didn`t wind across but bumped rear bag over it was OK but only did this on the last target.
Will post a couple of them also so you can see what i mean OK. And any solutions to the problem would be nice as well.
Anyway the mate got himself a FLY patch as he hit two Fly`s i came close but close don`t count.
Each of the rings on the FLY target are 3 eigths of an inch outside measurement is 8& 5 eighth inches

Well the groups are quite good but i think the rifle is capable of better i will weigh each load for the next comp and see how it performs will try that also with the next fly-shoot at 550yards.
Did anyone try a 30BRX when developing this round pushing the shoulder forward .100would like to know how much more velocity it produced also a longer barrel i presently have a 1 in 17tw 24" Pac-Nor just looking at a little more velocity to try shooting 150gr projectiles and keep them up to 3,000Fps.
 
Mine barrel 27.5 inches-
Bob do you want me to build a Dasher or BRX version for YOU to test with to give you some data and then when you have finished testing it- you give it back to me with the chamber re-cut to a standard 30 BR barrel at as long as you can??
I can furnish also some once fired Norma and Lapua 6mm BR for you to try with.

Just cost you the chambering job and testing componants and a re-chambering job at the end. Cheaper than buying a whole new barrel for prototyping.

This offer is for complete rifle to use as test bed.

E-mail me if you are interested to discuss costs, timing, etc.

Hello,
Is it possible to shoot with a 1-17 twist 150 grains bullets ???
thanks

a 1-17 Twist won't stabilize a 150 you'll want a 13 or 14 twist for this bullet, although my 10 twist 308 will drill the 150 BIB in the same hole at 100 yds
 
Is it possible to shoot with a 1-17 twist 150 grains bullets ???

It depends on the bullet length. While most people using the 1:17's shoot the bullets that are made on the 1.00 long jackets, the You can get a pretty good 150 made on a 1.080 jacket and Randy Robinett,BIB Bullets) makes a makes a killer 132gr.:10 ogive/134gr.:7 ogive bullet on the 1.080 jacket that stabilizes just fine in a 1:17.

I shot an entire season with a Lilja 1:17 using the 1.080 long bullets @2950-2960 fps. in the .30 WareWolf,46.9 water capacity) and the combo won every 100-200 HBR Grand Agg. and the season championship at the old Mason City, Iowa IBS club.

So, from a theoretical standpoint, if you had some 150's made on a 1.080 jacket, they would probably stabilize just fine. But...and here's what we need to keep in mind...there is a balance that you need to achieve based on bullet weight and case capacity. The 30BR is best balanced with bullet weights not much over 125gr., although you could probably make a case for the 132:10's on the 1.080 jacket..depending on the individual gun.

Two seasons ago,in a parallel test effort, Randy and I both tried using large .30 cal. cases with 1:17 and 1:18 twist barrels and the 118-125's at some pretty high velocities in our HBR guns to try and gain an advantage. I used a full length 284 necked to .30 cal.,the 30 BeWare) @ 3,400 fps.:eek: and Randy shot a full length 300WSM @ 3,700 :eek::eek:!

What we both found was that while the guns were accurate, they weren't accurate enough as compared to other well tuned .30's. Simply a matter of too much case capacity for bullet weight...an unbalanced situation.

Maybe Randy will chime in with his own thoughts, as well. But again..if you're talking about the 30BR with a 150, I think the cases capacity is way too small to achieve the best balance for accuracy.

And accuracy is everything. Decreased wind drift, low .es/sd numbers, blah, blah, blah :rolleyes: are all meaningless if you sacrifice accuracy. :) And we need repeatable accuracy..not just a single .250 group at 200 or something like that. That's where people don't understand the meaning of a guns ability to agg. well..that is: to consistently shoot the small groups time and time again.

Long winded, I know....hope this helps. -Al
 
What are the heavy bullet that a can shoot with 1-17,normalu bullets like hornady,sierra,lapua,....
 
AlNyhus,
Thank You, And yes it does help with the 115gr 6 ogive that i have made for me now accuracy at 100 & 200 yards is terrific and repeatable.
The accuracy at 500m is quite good also just looking for that little extra BC the BC of the 115`s looks to be around .360 have tried the 125gr Ballistic tips and they work fine also BC of .366 just thought if i could get up into the 150gr .436BC projectiles might just buck the wind that little better at longer ranges.
May just wait till we get some of the new 6.5X47 brass and neck that up to 30 will be buying another barrel to fit to another rifle so may chamber for 30X47 with the 150gr Match-kings if it works, great but if it doesn't can re-chamber to the same chamber as i have now and know it will shoot.
Just looking for something i can use at the longer ranges with long barrel life.
Will be shooting my 30BR again at 500m in July at another FLY Shoot and the mate is building a 7mm Ackly improved.
If i order a barrel now i might get it by October.
As for your offer Patrick, OGRE)you want me to build the rifle for you and pay for it as well just so i can test then give it to you chambered & fitted sure you don`t want me to shoot it for you as well? If i get a bigger gun cabinet i could store it for you too. HAHAHA GAGF.
 
NOT quite you old silver back.

I supply the rifle, barrel 1:10 27inch, brass, etc you supply the 30 BR chamber and formed brass-- shoot something with a decent BC and get your groups at 1000- drink AJR's free booze and then return the rifle to me with some life left in the tube for me to hunt feral with.

hows that???

w: I really don't know how long these bullets are. Your best bet if you want to try them in a 1:17 would be to measure each bullet that your interested in for overall length and go from there.

But again..a 150gr. from a 30BR,regardless of twist) is not what these cases are designed to work best with. -Al
 
OK thanks all

Now a can order a reamer,which would be the best choose

a normally 30 BR Reamer or a 30 Robinett" reamer
thanks
