Savage 12 LPRV 1:9 twist in a McMillan A2 stock with aluminum bedding block. The OAL is to the lands for my chamber. Should be within a few thousandths for someone with the same model rifle. (I used the Hornady tool to find it. Remember each bullet is different).

These are all with once fired LC 09 brass. I have had good luck with it. Better than with the RP or Winchester. Oddly the Fiocchi GFL brass (50 pieces)I have had good luck with also). No pressure signs.

205 Match Primers

Nosler BT 55g #39526 (not the 250 round Varmint pack ones, I think they are different)/Varget 24.9 OAL 2.332
Pretty foregiving with Varget. I can shoot from 24.6 to 25.9 and still be within 1/2"- One hole at 24.9 though.

Sierra 69 BTHP MK #1380- OAL 2.332 (2.342 to lands). 26.0 Varget (someone else on another forum had the exact same results on another forum, can't remember the name but his lands measurements were within 0.002 of mine. One hole (not a cloverleaf, one hole).

75 A-max's. Using RL15 and Varget I can't seem to get these dialed in. I keep gettin 2 about 1 hole then a flyer from 1/2 to 2" off. They are not keyholing..

so that is positive. Gonna try some viht n140 when I can get some. Recommended from Walt at Berger for the 70s and 73s.

Speaking of which, my initial OCW testing on those is promising. Using Varget, and checking POI I shot 18 rounds inside a quarter with 3 different Varget charges from 24.0, 24.5, and 25.0 (Berger says 24.8 is max, so watch for pressure signs) on both the 9 shots for the 70s and the 9 shots for the 73s. Each of those groups were touching each other (25.0 with the 73s pushed it outside of a nickel).

Gonna do 24.3, 24.5, and 24.7 now to validate and then mess with the lengths. Used 2.340 for the 70 and 2.375 for the 73 which put it at the lands.

Also, I have had better luck with the Nosler CC 77grains then the Amax's oddly enough. I have those shooting 5/16th without playing around with OAL. 24.8 Varget. The bergers both have better Ballistic Coefficients thought so I am gonna just use the rest of the box for foulers.

Email me at jjkuchar at gmail and I can shoot the excel spreadsheet I am using.

Hope this help some people.
 
When I get a chrony for xmas I will add that info

Ballistic coefficients
Nos 55g BT (orange) .267BC/.157 sect density
Sierra 69 BTHP 1380 .317BC/.196 sect. dens.
Berger 70 VLD .371BC
Berger 73 BTHP Target Match .343BC
Hornady A-max 75 .435BC/.214SD
Nosler Custom Comp BTHP 77g only .340/219sect density

Looking at this, if your rifle can shoot 'em, -Amax, Berger 70, Berger 73, then Sierra 69s are probably the way to go.
The 69s are proven and will give you better velocity range then the a-max would be my guess. Just gotta see what the 70 VLDs can do.
 
This is what Berger sent me.

Hi Justin,
The two powders you list are quite popular as is Viht N140 for these two bullets in the 0.223 Rem. Load data was generated using Quick Load a 24 inch barrel a COAL (cartridge over all length) of 2.260 inches and your COAL and velocity could be a little different.
AS WITH ALL RELOADING APPROACH THE MAXIMUM LOADS WITH CAUTION AS ALL RIFLES AND RELOADING TECHNIQUES WILL BE DIFFERENT. If YOU CHANGE ANY OF YOUR COMPONENTS; THIS INCLUDES DIFFERENT POWDER LOT NUMBERS; YOU MUST REFIGURE YOUR LOADS BY STARTING WITH THE MINIMUM LOAD.

If we can be of any additional help feel free to contact us.
Thanks for your interest and have a great day.

Super friendly and helpful peeps over there.

Hope this helps some people. I know I looked all over the place and found bits and pieces, but often times there was one or two factors that were different and didn't line up with my setup, i.e. 1:8 twist, etc.

I am gonna use Walts advice and try the viht n140. One thing I have noticed when using different brass, is I seem to get the best load when it the powder is just compressed. I will have to do some more research on that as a comparison to OAL. The OCW(Optimal Charge Weight-google it, good read) method rather than the ladder method seems to save some time with load development also. I know that will be my starting point for my .260AI when it is finished. I am excited about slapping that new Vortex Razor on and seeing what it can do.
 
75 A-max's. Using RL15 try 21.7grains . Slow but at 100yds should like the results. Works in several rifles bolts and semi autos. with the following powders. RL 15 H4895 Benchmark and IMR 4064.
 
Try some 52/53gr match bullets.

Fiocchi primer pockets were tight on me in general. Made for difficult seating. LC 08 is nice. Mainly, I use R-P.

R15, Varget, AA2230, and Benchmark have worked pretty well for me.
AA2230 covers a lot of territory. Some have good luck with the R15 and Varget in lighter bullets, but AA 2230 and Benchmark did better in the lighter bullets.

Hornady 68gr may be another good one. I do .6in with 69gr SMK and 75gr Hornady BTHP. 75gr A-Max is much different animal than the BTHP.
 
Try 23.3Gr H4895 with 69gr SMK CCI 400 Primers. Federal Brass, 2.26"OAL
Should put 10rnds inside a dime.
 
Got the SMKs shooting well for this rifle. Just hoping I could get Amax to fly consistent. :( Hopefully these 70 bergers can be my final answer. Ill know by the end of next week hopefully.
