    I have been wondering if anyone has much experience with loading the 308 with either the 110 or 125 grain bullet? I have a 700 Remington Varmint and a Browning A bolt with the heavy barrel and Boss. Both do a good job with the Sierra 150 (2130) bullet but I'd kind of like to take these rifles to Wyoming next year to shoot some pasture poodles.

    I'm thinking that you should maybe go the other direction in projectile weight? Those lighter projectiles will have a lower BC value and limit the range you can effectively whack those 'pasture poodles' due to wind drift and drop being exaggerated.


    YMMV!

    I Use the 110 V-MAX (bc .290)
    47 Grains of RL 15 (Magical .308 Powder)
    Nosler Brass (neck sized after firing in my chamber)
    OAL 2.750
    Fed 210M primer
    Velocity 3060

    In the 308 case you can push the 110's to 3200 but those loads are getting a little hot and accuracy suffers. The above load is an accurate load in my rifle and I've shot clay pigeons out to 825 yards with it connecting about 60 percent of the time. Calling the wind is the challenge with this load when I miss its a little left or a little right. I've used 125 NBT's in a 30-06 and accuracy was outstanding but have only shot those to 700 yards. Both rifles have a 1-12 twist.

    The 125 Nosler BT is a very accurate bullet but it is not a varmint bullet. It is a game bullet. It really works well on deer as long as you keep your impact velocity under 3100 fps. I use it in my 308 Win rifle to deer hunt with and it is accurate and drops them in their tracks out to right at 300 yards which is as far as I have shot one with this rifle. The 125 Speer TNT is a good varmint bullet as far as it coming apart on impact and accuracy. I use IMR4895 powder to get one hole 100 yards accuracy and top velocity.

    I recently built a 308 just for the 110 v-max. I have only 8 rounds thru her and they were for velocity testing only with 3 different powders. This gun has a 26" long 1-17 twist so this helps the velocity gain a bit.

    Velocity with hornady brass ran as high as 3400 fps without ejector marks with one powder, and in the 3325 fps with 2 other powders. The problem is all the powder types I tested were compressed loads so I will try somthing a little faster burning next round.

    I loaded some Speer 125gr. TNT hp.
    44.5gr. H4895
    CCI 250 primers.
    OAL 2.780
    that shot just under an inch at 100yds out of my Rem 7400 semi auto.
    Going to try them out on some coyotes.

    I have lots of 308s and never got a 1" group, but I did quick and dirty rebarreling on some surplus Mausers and converted them to 308 and took them to the range Jan 29, 2009.

    That day I had (4) different 308s shoot a 1" group at 100 yards.

    The load was 110 gr Vmax ~ 3000 fps.

    This is a wimp load, but it gets the job done.

    All those years of shooting 168 gr Match Kings never got me a 1" group.

    My Savage 12FVSS (1:10 twist) likes the 110 grain Sierra Varminter as well as anything I've tried so far, at least at relatively short range. I've been using 47.0 grains of Varget and seating them 0.015" off the lands.

    Good luck!

    I tried the Hornady 110 VMAX with IMR 8208 recently. I haven't settled on a load just yet, but it will be in the 47-48 gr range I'm sure. The rifle is an Armalite AR10T with a 24" barrel, with a 1 in 11.25 twist. I was shooting from a bipod and a rear bag. I was shooing Win brass shot who knows how many times, with CCI BR2 primers. Chrono was at 10'. I had to adjust 3 MOA down halfway thru as the bullets were walking off the target. You should be able to make out the rest of the info on the pics. The rifle notoriously sends the first shot astray, with the next ones touching. How touching, huh? Anyways, all off them shot around MOA or better.

    It will only let me post 6 images, so here's the seventh. By the way, I got the recipe from the folks at IMR. There were NO pressure issues with any of the loads, and I wouldn't hesitate to go a grain or so higher in my rifle. I really want to shoot some of the mangy coyotes around here with this load. I WON'T be keeping their hides.

    I loaded 30 rounds, in the 17 twist 308 today and shot for groups. 50.5 grains of H4895, *compressed load. (do not use in a fast twist rifle)(start lower)

    It was about 8 degrees, velocity varied quite abit from 3360-3438. not sure if it was the crono as it is stored outside in the shooting house where it is also 8 degrees.

    First I shot a 7 round group that put 6 into sub 1/2" at 100 yards. Scott shot another 5 shot sub 1/2", and I shot a third that was sub 3/4".

    5 rounds at 400 showed about 2" of verticle, 4 moa up, but the wind played hell with them.

    600 yards with 12 moa elevation put me on the steel gong sporatically.

    I put this rifle together for fun shooting and it is a gas, the mini muscle brake adds a bit to that fun, seeing the snow fly with the sighter shots at 600 yards helped with my come-ups.
