powder and bullet combos in a 223 bolt gun

hi guys, new to reloading and the forum, google has popped this sight up numerous times when i searched reloading info.

I have a Howa 1500 Varminter, all stock except a bedded bell and carlson stock. trigger is the decent two stage. thinking about lapping bolt lugs but haven't did it yet. 1-12 twist

my question is i have a few different powders, imr 4320, h335, 4198, and a neighbor gave me some benchmark to try with 50 grain bullets.

for bullets i have 36 and 50gr v grenades, Vmax 40's, TNT 50, Sierra 52 match king. It sounds like 55 is about the heaviest i want to go with my slow twist.

CCI 400 primers, Federal brass small print

What would you pick for a simple starting load and experiments. Im thinking the 50 or 52 with some benchmark. but i would prefer to use the other powder as i don't have very much benchmark. how far should i be off the lands about 30 thousandths? or should i be a little closer?

also, what is the difference between a powder meant for lighter bullets, 40ish grain vs something like a 55-60

I'd use the h335 and the 52 match kings. Should been a pretty good combo with the 1:12 twist.

Personally with my 223 bolt rifles using 52gr Hornady match. I load them to max mag length with extreme accuracy. Try it and see what works in your rig.

I have heard a lot about the max mag length but never found a answer for this. So what do you mean by that?

Re: powder and bullet combos in a 223 bolt gun

I'd double check the twist rate, as most Howa / Weatherbys I've seen were 14 twist. A 12 twist is a bonus. The .223 will shoot 55 grain bullets very well, and some 60 grain bullets. It's not the weight of the bullet anyway, but the ballistic coefficient. The twelve twist will handle up to about a .28. Yet something like the 53 grain V-Max would be about it. Try the V-Max in 50 and 55 grains.

I think I own five .223 chambered rifles, and my goto powder is usually BLC2. But I also use H322, H335, and XM2015BR. Use mostly Federal primers, but have also used CCI's. Federals are better, and tend to show up in cold weather.

I seat all my bullets within .004" of the lands, and usually within .002". My Remington has a 14 twist barrel chambered in .223 N.M. with a .246 neck. It likes the bullets to be with in .002" or less. But not jammed into the lands! My Browning has a 14 twist barrel and will shoot a .06" jump OK, but starts to do a lot better with bullets seated within .008" or less. You have to experiment here.

I am pretty sure it is a 12 as it is the bull barrel and howa spec sheet shows 12 anyways. With that BC would 400 yards be about my max distance then?

Re: powder and bullet combos in a 223 bolt gun

Max magazine length is the maximum length of cartridge you can still feed in your magazine.

As far as distance what are you doing with it?? It your shooting targets I've gotten 600+ yards from a 50gr nosler ballistic tip. With such a small bullet wind plays a huge roll in things but I have consistent hits with it at 600 yards when the wind allows.

Just practice long range if possible at targets and as far as I can if I have a shy coyote so I figure about 400 yards...
