I have a trued Remington 700 action with an 8 twist Kreiger barrel. It will shoot 31.7 grainss of RL15 and 105 Lapua Scenars consistently under 2" at 600 yards (5-shot groups). The cases are Lapua 6BR with CCI 450 primers. I have tried the CCI BR4 primers but got better resluts with he 450's.

NOTE: I have no doubt this is a good load for Jarhead. Some rifles can handle this much RL15. However, this load will be WAY hot for some other guns. Much depends on the freebore of your chamber and your bore dimensions. With RL15 and 105s we recommend you start at 29.5 grains and work up. A practical max load in many 6BR rifles will be 30.5-30.7 grains.

I'll throw in some data for the guys that like light bullets. I had a 21 1/2" HS fluted barrel (light varmint), .265 neck match standard match chamber. I shot my 60's at 3550 with 33.5g of H335 with a 7 1/2 primer (205's too thin cupped for this load). My bullets have a .2433 shank with a .2436 pressure ring.
In a 27" barrel, this same load shot 3750 fps. Accuracy is extreme (Gene Harwood set a NBRSA 100 yd record with the 60's at 3700 fps with 335).
Due to variations in lots of 335, I would start off at 31.5g and work up. In the guns that I have shot, the hotter the load, the more accurate it got...every gun is different.

I find that:
36 gr H335 65 gr Vmax moly will pierce CCI450
35 gr H335 65 gr Vmax moly will not pierce CCI450
35 gr H335 65 gr Vmax moly will pierce WSR
33.5 gr W748 75 gr Vmax moly will not pierce CCI450
33.5 gr W748 75 gr Vmax moly will not pierce WSR
33.5 gr W748 65 gr Vmax moly will not pierce WSR

30" 1-8 tw. barrell
I found this weekend,at 300 yds, 28 gr. of Benchmark pushing a 107gr. SMK gets you v-bull after v-bull. BR-4 primers, length of 2.250"
I tried 30 Gr. of RE-15 recently pushing Lapua 105's and at 500 and 600 yds its absolutely deadly accurate.
Works well at 900 and 1000 as well but losing out to the 6.5 x284's.

My rifle is a Sako AII with braked 24" Hart barrel, 14" twist. The chamber is .010" longer than brass, .272"nk, 0 freebore. This is for prairie dogs, not target shooting or anything else. It's fed a diet of light bullets 55-65gr. Bullets are seated .005" off the lands. All are coated with a film of Lee Lube.
I've tested Reloder 7, Reloder 15, XMR2015, AA2230, AA2230-S. Most accurate powders are listed below.
Reloder7/55BallisticTip/Rem.primer - No overpressure signs with any of these loads.
30.0 = 3638
30.5 = 3706
31.0 = 3780 Most accurate
31.5 = 3832
In my rifle, AA2230 gave best accuracy and velocity. No signs of overpressure.
AA2230/Sierra55BK- primer test Rem7-1/2BR/BR4
34.5 = 3777(BR4)
35.0 = 3864(BR4) 3851(Rem)
35.5 = 3970(BR4) 3919(Rem)
34.0 = 3708
34.5 = 3776
35.0 = 3855
35.5 = 3923
33.0 = 3607
33.3 = 3684
33.6 = 3710
In this rifle AA2230 is just magic. But different lots of this powder would shoot very differently. Enough to about drive you crazy. These loads are from a keg bought in summer 2005 and it's hotter than some older stuff, also accurate at higher velocities. Some of them grouped in the .1"s during load workup. When it's time to put more together, the load will be 58Vmax/55BT's at 3855 or 3919. The 65's at 3675-3700 shoot awfully well too.
