6mm 95 grain Bib bullets

[Jeffsavage]

Has anyone tried 6mm Bib bullets in a 8 twist 6mm br, if so were the results good? Thanks.

 

[groupshooter22]

Im using them in my new Brux 8 twist. So far it likes them the best of course next is the Berger 108. Only shot at 100 so far but the Bibs shot a .106 today and the Bergers shot a .244 last Wed. Keep in mind my barrel is practically new with less than 200 rounds fired and Im still working on loads so I am not shooting the same load twice. I will definately see if that combo repeats or not.

I am shooting them in my 1:8 6BR and my 1:10 6BR. Outstanding results with RE-15. Absolutely great bullet. Only shooting it out to 300 yds. Luck, tim

 

[cmillard]

not to change the subject, but are the 95 BIBs a FB or BT?

 

[groupshooter22]

The 95s are flat base and with a chamber specd for 107s the 95s base goes almost to the shoulder.

Jeffsavage,

The 95 Bib's are great bullets. you just need to watch how fast you push them. The 95 gr Bib's can come apart if pushed too fast in a 8tw. You should be ok in a 6BR. I have seen bullet blow up on guy pushing them hard in 6 Dasher

Thanks for the info guys, I found a fine gentleman that is selling me 100 so I can give it a try.

Bullet failures are as much an individual barrel attribute as a jacket/bullet attribute: using a faster twist than necessary drops another 'straw on the camel's back'. I have some local coyote hunters using the 95 Gr. BIB FBs and, via 6MM CatBird and similar wild-cat chamberings, driving them in excess of 3700 FPS through 9 and 10" twist barrels. Last season, just to prove the barrel issue to myself and some pals, I shot some 121 Gr. FB bullets, based upon the 1.300" long J4 jacket (LONG braring surface - Lots of friction ) through a Broughton [5C] 1:8" twist, Dasher chambered barrel, during the Iowa State IBS Registered Group Championships (100/200 Yd. Group). Not the slightest hint of a bullet failure - shooting against 30 or so PPCs, the rifle/bullet combination performed well enough for a pair of 2nds at the yardages (yes, the moving backers were operating ;D). Though I have tried, when using this barrel, I have been unable to cause a bullet failure - even at case wrecking pressures.

The paradox was evidenced when several barrels which I have chambered to 6/250 Ack. Imp. and 6x47 Lapua: depending upon the individual barrel, but especially when the twist rate is faster than 1:9", some barrels (particularly TIGHT - .236" - bored ones) destroy bullets (regardless of pressure) at velocities as low as 2900 FPS, while the next barrel (from the same maker) will not wreck bullets [from the same Lot] at over 3200 FPS, and 'primer-blowing' pressures - "go figure". Bullet failure is a perplexing puzzle. RG

Not that I need to top the comments of RG himself about the capabilities of his bullets, but I shot some 95 BIB in my 28" 1:9 twist 6mm Ackley. With a full case of RE-19 I was driving them right at 3600 fps. I will try some RE-17 the next time I shoot them. I shoot a couple of hundred rounds at the 300 yard target. Not one failure in the lot. Granted it is a fairly fresh barrel (less than 500 rounds), but it has never been babied. If it lives to 1200-1400 rounds I will be pleased. Then we will set back and start again. Tim

RG,

I shoot your 95gr in my 6BR 10 tw with great accuracy out to 600 yds, and have never had a failure. I have seen a few with guys shooting them in 8tw Dasher at very high velocities. I have seen this with other lighter bullets in 8tw barrels, they just can't take the twist.
This is why I tell guys to shoot the tw for the bullet you want to shoot. Some guys like to shoot a 8tw and shoot all weight bullets. It just does not work that way.

I shoot 14tw for bullets up to 75gr, 12tw for bullets up to 80gr, 10tw for up 95 gr, 8tw for 108gr. I have not tried the 9tw. I would like to try one in a 6BRX for your heavy bullets.

I am done with the VLD, they can run you crazy. I will shoot a FB when I can, got that from David Tooley and Joel P. shooting your 187gr 30 cal.

[skeetlee]

can you shoot these 95gr bib bullets ina 10 twist 6br? Thanks Lee

 

[MarkS]

Lee,

They shot great in my 10tw 6BR

Mark, I am just getting my 6Br 272 neck, 26" 1/10 twist Shillen up and running. I am waiting for my 95 BIB FBs to come in. What powders worked for you and the 95 BIBs? I usually use VV135 for 6 BR. Thanks, George

 

[MarkS]

Woodman,

I use N135 with the lighter bullet. You can try it it may work fine . I like Varget for heavier bulltet, RL15 would work also.

Hey guys, I've got a new 28" 10 tw barrel for my 6BR (yet to be chambered) and will be looking for some suggestions. Just what is a "Bib" bullet?

Thane

 

[MarkS]

thane,

BiB Bullet are made by Randy Robinett "RGRobinett " for the above post. Look him up and get 95gr for your 10tw.

I wonder if these bullets will be available in Canada.

Hi RG , As you know i run your 187s, at just under 3400 fps with a bearing surface as long as they have and in a 32 inch barrel ,you cannot get away from heavy copper fouling .. I have learned to live with it and one of the things that has helped was to never run a dry bore on the 1st shot even though i have never had any bullets blow up.. I use a WD40 style product made here in Australia to lube the barrel for the 1st shot after the clean and it surely helps with the fouling.. Henry C had trouble with the 121s in 6 mm exploding in one particular barrel , after he contacted me he started lubing the bore the explosions stopped even at full speed in a tight twist .. Mabye worth a try.. Seasons Greetings to All from LRBR in Hot and Steamy tropical Nth Australia..JR..Jeff Rogers
