300blk

I made a trade for some parts to put together a rifle for my wife. In the parts are a Steven 200 short action. Came with 2 barrels, a 223 sporter and a new 300BLK. I already have a 243 barrel that I was going build with for her. But the 300 seems a little intriguing. Was wonder what the plus or minuses are for having a bolt action 300BLK.

I believe this barrel is one of the barrels from the group buy from gun shack a few years ago. 16.5 inch threaded for suppressor, I don't have a suppressor but have been consider one.

The rifle one mainly be used for hog hunting and deer hunting out to 100 yds.

The 300 BLK is a great little round, excellent for deer and hogs out to 300 yds, and plinking, much further. I'm building a bolt action now myself. You will need to buy an improved extractor from SSS, as the factory extractor doesn't like the 300 BLK cartridge. If you go suppressed, the advantage to the bolt action is, that it will be super quiet.

+1 on what Slicky said.

You may want to poke around in the 300 black out forum. http://www.300blktalk.comSince you already have the barrel, you may want to give it a try. I bought one for my better half and ended up buying one for me a couple of months later.

There is no way on earth I'd use a 300 BO on deer past 100 yards, much less 300. I can only hope that's a typo.

The hottest load I can muster from my 7.62x39 is 2250 fps. with a 160 grain FTX. That carries 1100 ft. lbs. to 200 yards, which IMO makes it a legit. 200-yard deer round. But only if I handload that combo. Factory loads I would never shoot a deer past 150.

And the 300BO cannot match those ballistics, which is why I say it's a 100 yard deer round max. Sure, people will shoot, and kill, deer and pigs beyond that. But why, when there are so many better low-recoil options? Just to say you did?

I did a lot of research on the 300BO and 7.62x39 before I ultimately decided on the 7.62x39. The more I studied, the more I realized the 300BO just didn't make much sense in a bolt action. The 7.62x39 however, makes a lot of sense in a bolt action.

Just my .02. I know there are plenty of 300BO fans out there who will disagree. But math is math.

You are correct, math is math, and with the available bullets today, 300+ yds is not only possible, but works quite well. You have to look past kenitic energy, and look at a bullet's threshold for expansion. You put a proven low velocity expanding bullet in the vitals right behind the shoulder of a deer or hog, at a higher velocity than the bullets threshold for expansion, and you will be taking meat home. Simple as that. The math don't lie.

Barnes makes the 110 gr TAC-TX specifically for the 300 BO application. I've read on other forums these bullets will tear apart in higher velocity cartridges so it may be just the right picking for the BO.

My hunting buddy got a chance to test his 300 BO AR pistol on a blacktail fork a few years back. Shot it at around 45 yards and it toppled over dead within 50 yards.

That's the go to bullet got light supersonics in the 300 BLK. I shoot the 135 gr Sierra Varminters at ~2150 fps, they were also developed for the 300 BLK specifically, and will expand down to 1400 fps. That gets you to around 325 yds with reliable expansion.

While others are fond of the cartridge, I just couldn't find a reason to own a rifle in it (who knows maybe one day). It's a neat looking little round though.

It's fun to watch my friend shoot his at 500 meters. You can totally see the bullet being "lobbed" over with cool "slow mo" vapor trail.

For hog and deer within 100 yards, I'd be very confident in the 300blk with the 110 Barnes as those above me mentioned. I would definitely go with the 300blk if you're going to get a suppressor. A subsonic in a 300blk bolt action is so quiet it'll make you laugh. I'd love to shoot a critter with one just to really hear the "whop!" Get a scope with drop compensation reticle though because it drops like a brick.

If you're not serious about the suppressor or want to shoot/hunt past 150yrds or so without worrying about holdovers so much, .243 would be the way to go, although shot placement is still important especially on bigger deer. My dad swore off .243 for deer after he lost a nice buck despite hitting it in the vitals, broadside. This was back in the day when he had to walk uphill both way to track it though so no telling which bullet he was using.

I think I'm going to stick with the 243. I just can't seem to find a good reason for the going with the 300blk other than getting a suppressor.

That'll be a nice rifle for her. Now you just need to find two more stevens actions to put those other two barrels to work!

Those Stevens actions seem to be getting a lot harder to find.

Good choice going with the 243. It'll make a fine rifle for your wife.
