Looking at buying my first 308 this winter and started looking at reloading tables for the lighter bullets. My question is: When using the lighter bullets, do you lose accuracy to get higher FPS? More specifically, if I use 130gr bullets will my 4 shot groups at 100 yds be larger than 180gr bullets? I want this to be my primary deer rifle and match my 270 win in performance if possible...

thanks

No. I've shot a couple 5/16" groups using Barnes 130gr. TTSX in front of some TAC. The same gun can shoot 125 gr. Ballistic Tips with RL10 well under an inch, as well.

THe 308 with 130's will thouroughly surprise you on paper.

The barnes 110's and hornady v maxes shoot stellar out of my 308 rem vtr and my 3006 tikka. The barnes 110's are darn near as "long" in visual appearance as many stubby 150 grain .308's.

Now you can crank these 110's up to pretty amazing velocity but of course once past about 250 yds they drain off speed real quick and start dropping out of the sky.

I've had stellar groups with the 110's all the way to 350 yds which is the max at our shooting range.

Whether or not the 308 can match the 270's performance will be argued long and strong here. For sure it can to about 300 yds but after that the BC of the 270 bullet I would say would pretty much take over. And of course the 270 can push the 110's in it's class really fast too if you are looking for flat, short range performance.

The 270 is NOT the ne-plus-ultra of hunting cartridges. It may be popular but that doesn't make it the standard by which all others are measured.

I'd take the 308 any day. Not arguing with you Kraky.

Don't want to argue with you either but here in Wisconsin and many other areas it is considered to be a really great deer cartridge due to the bullet being plenty enough for deer, good available speed, ballistic coefficient, SD, and not bad on recoil. If it isn't one of the great deer cartridges I'm not sure what else it would be good for. It's not a great choice for varmiting and certainly there are better choices for bigger game.

Only your rifle can tell you that. I have a .308 with a Pac-Nor barrel put together by Mickey Coleman and the bullets it loves the most are the Nosler 125 BT and the Sierra 125 Spitzer. It shoots 150, 165 and 168 grain bullets pretty good but is a bit finicky on the load and bullet style, but it shoots those 125 grainers into little groups with a variety of different powders and charge weights.

FWIW, I've found the Sierra 125 grainers to be accurate in just about every .308 and .30-06 I've tried them in, this is going back 35 years. Possibly a bit too lightly constructed for what you want but I wouldn't be afraid of ligher .30 caliber bullets at all.

I just picked up a box of 125 Nosler BT and a can of TAC. I something doesn't happen to screw up my plans I should know how they shoot in my rifle by Christmas. I'll let you know what happens.

Have had some very good results from 110 gr Sierra hollow point varmint bullets, also 110 Hornady V-Max.

The 125 Nosler Ballistic Tip has proven very accurate. Very effective on deer too.

Long ago Dad and I used to blow up rock chucks with the old 130 gr hollow point Speer - it shot real well too.

The light bullets can be a lot of fun, and still retain very good accuracy.

I'd not worry about matching the your .270 with this .308 for any reason. Let your .308 decide what it likes to shoot and the best place to start IMHO is with 165/168 gr bullets. In every .308 I have owned, this weight of bullet has been outstanding particularly Hornady SP's and Nosler Partitions.

The .308 can shoot as far as you can and then some, so why be concerned about matching your .270?

SAKO75, I agree, twist has much to do with it.

Twist is important. I've got a 1-12" SPS Varmint in.308 for which I'm going to run up an OCW series using 125gr Remington Corlokt PSPs that I've had forever but have had little use to load for until now.

All depends on the rifle. My M70 EW shoots 150s and 165s great but not so hot with the lighter bullets. But that's OK with me.
