I'm close to purchasing my first 308 (custom r700 w/26"barrel) and I want my hand loads ready to go when I (finally) receive this rifle. Obviously every rifle is different, but it doesn't hurt to receive some factual information based off personal experience. So lets here it fellas. What bullet/powder combos are you punching sub with?

since it's custom, your choice of bullet will depend on what twist you selected. generally, when commissioning a 'custom' rifle, people pick their bullet first and let the gunsmith know so they can pick a barrel with optimized twist and ream a chamber to a depth appropriate for that bullet.

if you haven't done that already... my advice would be 168g SMKs with R15 or Varget.

you may get better responses in the reloading forum

For 1:10 twist, 168 or 175 Sierra Match BTHP over IMR 4895.

Should still shoot 168 match very well. Buy a few boxes of Federal 168 Premium Gold Metal Match.

I'm running 44.5 grains of IMR-4895 over a 168 gr Nosler hpbt, remington brass, CCI LR primer, pretty consistent 1.5" groups at 200 yards. My rifle is a Remmy 700 SPS Tac with a 1:12 twist.

I'm partial to 2 powders for the .308: IMR4895 and RL15. I typically use IMR4895 for 144-170gr bullets, and RL15 for the 175-178gr bullets.

I have 1:12 twis in my 20" FN PBR rifle and I have found fantastic accuracy running 125 grain Sierra Spitzer bullets and IMR4895, it makes for a very fast flat shooting round.

For long range, over 300 yards, you need the superior BC of the 168's and 175's, compared to the 125's. Plus, they don't get pushed around by the wind nearly as much.

As far as rifle twist goes, I've shot Winchester 180 gr power point's out of my 1:12 twist remmy 700, they printed an inch at 100 yards. 1:12 is fine, even for 180 gr bullets.

Quick question, how many hand loads do you intend to make before you get the gun? I would think you should try some different options to see what works best in that gun. Different power, charges, bullets. You could make up a big batch that your new gun just doesn't like very well. A lesson learned by a lot of people. Just like buying different ammo until you find the one that works the best, I would think hand loading would be a similar process.

Blackops,

I've shot some smokin groups out of my R700, with this recipe:

Sierra SMK 168, IMR 4895 42.0gr, OAL 2.80, CCI Large Rifle Primers, Lake City brass

I went ahead and purchased a couple boxes of the Sierra 168 hpbtmk's. I was going to buy these no matter what. I have yet to come across anyone that hasn't liked them. I think a pound of IMR4895 is next on the list. Anyone have experience with Berger? They seem to be a serious bullet as well.

Powders I generally use for my 308... Reloader 15, IMR4895, AA2520

As for bullets, when I want to look good, I use Sierra 168 gr. HPBT Match Kings or Hornady A-Max 168's, and when I want to just plink I use 147 gr. bulk FMJ's or demil'd bullet pulls.

At really long (stupid long) ranges, the 172 Scenar or the 175 Matchking do better because they stay supersonic out to 1k. Varget will get you the needed velocity. All that said, my 700vs really likes the 168 SMK and H380.

I like Varget and RL15, but a real surprise for me has been Ramshot TAC. Stuff is very accurate. Using 155 Scenars I get supersonic to 1200 meters, according to the ballistic software.

I load Varget, in Lapua brass, Fed primers, and either 155 gr AMAX's for shorter range, or 155 gr Lapua Scenars for long range. The Scenars have basically the same BC as the 175 gr Matchkings, and I can run them faster.....whats not to love;)

I've been having good results with H335, TAC and just picked up H4895 due to many recommendations on various forums.
I am shooting NM M1A using 168 and 175 grain SMK's. Looking for the "Holy Grail" load for this gun.
Your results will vary.

It seems to me sierra 168h pbtmk's are tough to beat out 600 and the 175's beyond that. Im going to assume nobody prefers berger for a reason.

actually lots of people prefer berger. they're quite popular in high-power matches
