Anybody find any ball powders that work in a 6mm BR reliably w/ good results? Figured since Ramshot Tac and Big Game bracket Varget that is supposed to work well, and Hunter is in the H4350 range, that one of them should work OK?
Thanks,
Monte

Kyle Brown set his world record with a pretty hot load of H4895. I checked the Results of the MT 1000yd champs Aug. 14-15, and Kyle shot a 6.93" group with a std 6BR and won his relay vs. mostly bigger guns. Kyle was 2nd Smallest group for match. Leo Anderson beat Kyle with a 6.67" shooting a 300WSM, but basically Kyle's 6BR spanked the rest of the field.

Interesting from the equipment list--Leupold is losing ground to Nightforce Big-Time. Leupold needs to make a 20-40x zoom and they need to fix the internal tracking. Why you should immediately have to send a brand new $850 scope to a specialist to get it to stay on target is beyond me...

Monte - I tried TAC in my 6BR Imp. Ubl while trying to fireform with Sierra 85BTHPs. Don't recall the charge weights offhand, but started out fairly low to get a baseline - result was cases with rounded shoulders, not fully formed. I bumped the charge up .3gr at a time, loading one round and firing 'out the back door', more or less, until I reached the point where the CCI 400 primers I was using came out blanked. At that point, the cases were more fully-formed, but still not as well as with Varget & S107s. Same thing happened with H4895 & the 85s, also with CCI 400s. Eventually, I loaded a bit over 30grs. of H4895 and used 7-1/2s with moly'd 85s, and got decent accuracy, normal appearing fired primers, but still wasn't doing as good a job forming as with Varget/107s. The main reason I was messing around with the 85s was that, at that point, I wasn't getting good 600yd. accuracy with the 32.5gr. Varget/bare S107MK load I'd been forming with, and couldn't see wasting expensive match bullets on loads that didn't perform well enough to use in a match. Switching to moly'd 107s and bumping the charge to 33grs. pretty well resolved that issue. Still haven't tried TAC in formed cases with 105/107s - mostly because of the great results I've been getting with Varget.
However, I have over 16lbs. of TAC on hand, and might be tempted to do more testing with it at some point this fall. I'm using a Lyman 1200 DPS AND check-weighing each charge of Varget in an effort to keep the ES & SD numbers as low as possible - while TAC runs through a Harrell's meter consistently enough so that no check weighing would be neccessary, and would speed up the loading process considerably.

In Europe ( France , Belgium ..) SNPE Nobel powder as know as SP 11 is a very good spherical powder , this powder is made in Poudrerie de Clermont in Belgium and some PCL powder ( original name ) are resale in USA under RAM powder brand .
PCL 511 and 516 works fine in 6 Norma BR
good shooting

I just got off the phone with Dan Dowling (well-known smith who invented the 6 Dasher). For his 6BR varmint gun, he uses AA2230 and AA2200. AA2230 is a double base spherical powder developed for the .223; you can often find it in surplus form at very low cost. It meters so easily Dan uses it to load Varmint rounds on a Dillon Progressive. He loads about 32.5 grains with a 58gr V-max bullet and Fed 205m or Rem 7.5 primers. This is with a standard 6BR case. He says the progressive-loaded rounds easily hold .5 moa and he's getting about 3700 fps.
Another low-cost powder to consider is IMR8208. The original application was U.S. 5.56mm NATO Tracer M193 ammo, loaded during the '60s and early '70s. A very fine extruded powder, this a good choice for the PPC and 6BR cartridges. Can be loaded using Hodgdon H322 data. This powder is known to deliver great accuracy, and costs $110 per 8-lb jug from Barlett Reloaders (GIbrass.com).

I'm going to be trying some H4895 and seeing if I can just throw directly into cases from the powder measure. I've been using Varget and I trickle each charge because, using an RCBS measure, sometimes you cut the kernals and that throws off the charge by .3-.4 grains.

Has anyone tried any further on this?
I'm interested most specifically in the Ramshot line.
TAC looks promising, with the possibility of Big Game working as well.

I tried Tac awhile back, I found it to be very dirty, velocity was down, this was 2 months ago, maybe I will give it a try again, I called Ramshot and they did say they were in the process of doing some load testing with the 6BR

I tried alot of different powders with bullets 100 grains and heavier and here are my 3 choices.Varget,H4895,H4350 if your shooting light bullets of less than 70 grains H322 shoots good groups but velocity is down.The ball powders i tried never gave me anything encouraging so they were dropped.

Well, I contacted Ramshot Powders the other day on it. Here's what I recieved:
Sir,
Thank you for your interest in Ramshot Powders. We have not yet completed testing for the 6BR. The only starting load I have is, with a 107 grain bullet you should be able to start with around 28.0 grains of Ramshot TAC and work up slowly. I hope this information helps.
Western Powders, Inc.
-------
Further emails where I asked approximately what velocity that load would run resulted in a response of "We're not sure, because that load was never tested in our lab".
Hmm.
I think I need to get some H380 and a couple hundred CCI-450's to try out

Well, I tried copying the data from Quickload so you could look at it, but it doesn't want to stay in a readable format.
But I'll probably start at 29.5, check my velocity as compared to the quickload report, and then depending on the results, quickly work my way towards 31 grains (should be near max). But I'm using moly, so if you want to try it with naked bullets I'd take half a grain off of the starting and max. At 31 grains I should be looking at a bit under 2800fps with my 24" bbl. Pretty much identical to the Varget load I'm using right now.
If you want the full data sheet just email me: darkeagle10x@gmail.com, and I'll send it to you.

After cogitating over the results I got with Big Game, I'm wondering if it might be a good choice for Tubb's new 115s in improved BRs like the Dasher & my Ubl. 36.6grs. was slightly compressed with a S107, so there's bound to be a little more compression with the same charge & a 115. The guy who talked me into getting into the 6BR Imp. has a Quadlite with a 28" Krieger chambered for the same Improved BR that I'm shooting, and has chrono'd 115s at around 2950fps with N550 - so we feel the 115 is a viable bullet in the BR, or at least in improved BRs with the additional case capacity.
