Loading for semiauto browning mk3

[cjmac]

As im waiting to find a used browning mk2 in good shape , or if I can't ill buy a new mk3 . Im looking for advice on loading for semiauto rifles. Iv always loaded for bolt guns . But Never for a semiauto . It will be in 308 , Any recommendations and advice on powders and such is greatly appreciated....

I would prefer to have an older browning mk2 as I hear, they are better than the newer ones . The newer ones from what I have seen and heard seems to be about a 50/50 rather thay are really accurate or not . Some say they can't get him to shoot any better than three inches at a hundred yards. While the others are under 1in at 100 yards . All I need it for is deer hunting at two hundred yards. If it'll shoot a 3 shot group 1.5in or less at 200 yards im perfectly happy with it .
The newer ones have a 1in12 twist and have heard thay like like the lighter bullets . Not sure if there is really any truth to that

Thanks , chris

What bullet?
I've had great success with Hornady 165gr. With Varget and H4895

Or 125gr with Benchmark

When I read "Browning MK II or MK III", my mind immediately goes to the BHP pistols of the same designation.

I was thinking about 150g Sierra btsp or maby the hornady bullet with crimp ring .
I have plenty ov varget just didnt know if it would cycle it properly

Nice

H335 would be an excellent choice for the 150gr bullet but definitely pay attention to temp sensitivity

Thats why I like varget. I use it in everything. Just wasn't sure if it would work in a auto

I had MK2 30-06 and used IMR 4350 with 190 MK bullets but I think the .308 does better with IMR 4064. It's hard to beat IMR 4064 for accuracy if it will shoot good. But I'm sure Varget also a good choice.

IMR 4064 is my favorite .308 powder ( also for other cartridges) but good luck finding any.

I would like to have a mk2 but cannot find one that is in good shape. Or isn't the extremely overpriced. I'm hoping that bargain. It will work with a semi auto mostly for temperature stability.I've always had very good luck with it

They have some here at a local shop. I seen it the other day.

I have a MK3 DBM model in 308 and it shoots 150gr Lapua Mega SP’s well and does a great job on deer…the deer haven’t made more than a few feet after the shot. Not sure of the powder I used, I’ll take a look if i interested.

Seems to be an accurate one, but to be honest I just loaded a few rounds, sighted in and took velocity readings, then used it for hunting and it’s hit right where I’ve aimed on 5-6 deer now out to 175 yards…I’m more than happy with it.

It’s a shame. I have one sitting in my safe in Texas. It’s in the cluster of “guns I’m going to sell”. I bought it 15 years or so ago and put it in the safe. When it came in, I decided it was too nice to take into the field.
