6mm BR , 75 V Max, Powder ?

[ncageneral]

I must admit I reluctantly have to ask this question. I've read through every thread I can find and have yet to find a definitive answer. I have come across a truck load of information regarding heavy bullets and Varget (105 and such), 75 V Max and Varget , H 4895, and a various cross reference of other powders. With powder being hard to come by I will be forced to use what I have, which is plenty of RL 15 and AR Comp. A limited supply of CCI 450's and a good supply of CCI 400's. RL 15 in my past experience has behaved closely to Varget which shows up in a lot of preferred loads, AR Comp behaves similarly to IMR 8028. Does anyone have a load recommendation with either RL 15 or AR Comp under 75 gr V Max bullets? I am not out for 5 shots in 1 hole at 100 yds. I intend this rifle to be a coyote rifle, so anything that will get me a starting point will help. Like I said, I really feel like a dummy for asking this question. I've been shooting and loading for quite a while, nothing like the bench shooters that I see posting on here.
Thanks, don't be too hard on me.

If ARComp is really like 8208 start at 30 grs and work up till you find pressure ,
I can’t believe it won’t shoot plenty good enough to shoot varmints with

I use H335 with Rem 7 1/2, tiny groups, lot easier to clean then R15 or Varget and great velocity.

60g Sierra, 70g Nosler Ballistic tips are fantastic coyote killers, along with ALL 68g Benchrest bullets made off of J4 Jackets.

these days you shoot what you can get. but in the good days of buying what you wanted .
i'd shoot a 65gr. vmax or a 70 gr. nosler on imr 8208 . and the real secret sauce is n135
nothing in my br"s has been better .me and my buddy's have shot hundreds of coyotes
with those two bullets they blow big holes in predators . good luck buddy any gun that shoots
around 1/2 inch kills predators all day long.

I used AR-Comp with the 75 V-Max in my 6mm BR. Ran a ladder from 29.5 grs to 31.5 grs in 1/2 gr incurements. All the groups were good but the 31.5 gr group stood out ( 3349 ft/sec). I was using Laupa brass and CCI-450 primers with a slight jam. As a side note, AA2230 also worked good with the 75 V-Max in my rifle.

55g Noslers in a zero freebore, 27" Lilja 3 groove, 12T is 3900 right on the nose with Rem 7 1/2 and AA2230, use a Harrells die to size with on every firing. IN the calm, groups have been as low as 3/4" at 300 with the 55g Noslers, and is so flat shooting, reminds me of my 22/250 AI with 55's. BC of the Nosler 55 in 6mm is better than the 22 caliber counter part.

Groups at 100 barely open up a bullet hole if you have the glass and can read left and right with a wind flag.

I believe my buddy is running IMR3031 with 75 vmax in his 6br. Trashing pdogs.

Agree on the AA2230.
The lot of 2230C that I have is even better. Sadly I'm down to 6lbs of it.

The Berger book lists RE15 for 69 gr bullets as 31.0 to 34.6 and 80 gr bulkets as 30.0 to 33.3. That info should give you a starting point.

Yes sir, I think I can cypher that out to where I don't blow myself up. Thank you

@mr.big is dead on with his advice on the 8208. I picked up 32lbs several years ago at a good price for prairie dog powder in my BRs, 55gr noslers if the wind ain't to bad and 70gr noslers if it picked up. Didn't find out how well it works in the BRA with Barts 103s at 600 till I got a bad batch of 4895 and had to try something new, it's very versatile, just sneak up on the top load because it peaks pretty quickly..

N135

Winchester 748 works very well.

 

[ghostrider272]

Running AA2460 and CCI450 primers.

Ar Comp at 3350 is ideal. AR COMP is better in nearly every regard.

Well, 75 V Max grouped almost as well as buckshot at 100 yds. 70 gr Nosler Varmageddon's did much better. Minute of coyote easily. I think between the 58's last week and the 70's this week I am about done. Thanks for the input gents. This has got to be the easiest load work up I've ever dealt with.
