Help...Can i use these projectiles?

[Juiceking]

Hello THR Family

So i just put in for my hunts and im wanting to start messing with some rifle stuff. I inherited a Win mod 70 .243 along with reload kit and components.

I found these projectiles and i was hoping i could use them all to load my .243 but probably not.

Please see pics but yellow box: speer 85 gr 24 cal. (243) BTSP

and obviously red box Hor vmax 6mm 58gr (.243)

So please educate my stupidity

6mm or .243 is the same bullet diameter. Everything I see in your picture can be loaded in a .243 Winchester cartridge. Just work from a good reloading manual which explains things. I am not a 243 type but have seen .243 Winchester loaded using a variety of bullets between 58-60 grains to 105 grains.

Just make sure you use good known load data and learn the process in small steps. Ask questions!

Woohooo you guys made my day i was just confused because of 6mm and they are different lengths. Oh man that gives me a lot to play with if i draw thank you so much.

As far as reloading i totally get you...im a rookie reloader about 600 rnds of .223 .40 and 9mm and ive shot about half of that.

Find your twist and that will determine your maximum weight limit. Stability matters a lot to accuracy. With long barrels you can get a little more speed to give you a few grains of wiggle room.

They're different lengths for a couple reasons. 1st, since they are all the same diameter, when the weight is increased the mass has to go somewhere, as in the length. 2nd. there are various bullet shapes due to intended flight characteristics and for terminal ballistics, that is to say, how the bullet expands at target.
Get yourself a good loading manual or 2. Study, and re-study, before building live rounds. It's not a bad idea to practice building dummies, but don't even do that until after you have studied and understand your manual(s).

BTW, I suggest those Sierra 100 gn spitzers are a great deer killer. Those 58 gn V-max will give a coyote a very bad day.

Well figure it this way. When I add weight to a bullet of a given diameter since I can't make it fatter I can only make it taller.

Find your twist and that will determine your maximum weight limit. Stability matters a lot to accuracy. With long barrels you can get a little more speed to give you a few grains of wiggle room.

You may want to keep that in mind. My 6 PPC barrel has a 1:12 twist and for good accuracy I had to stay below 68 grain bullets. Find the bullet and load that works best for you in your rifle.

Ive read good things about Sierra and i have book from them from Uncle...definitely be pulling that out thank you

 

[Juiceking]

So assuming i did blue painter trick right is a 1:10 twist. So im seeing that means im good up to 105gr bullet?

 

[splattergun]

right. 105 - 110 maybe

 

[Juiceking]

Man you guys are great you got me on track. Igot few reload books with kit and i just never looked at this one. Assuming i draw for something this will be my first time ever reloading for a hunt. Super excited

The front matter is more important than the tables imo. Understanding the process will put you much further along than just loading the proper amount of powder

 

[BBarn]

A 1:10 twist may not work well with bullets over 100gr. The length on the heavier 6mm bullets can cause stabilization problems. My 1:9 twist won't stabiize some of the long, heavy VLD bullets.

Just wait until you harvest game with your own loads. It just so happens that the first year I hunted with my own loads I yielded a buck that is on the wall. Crazy story to go with it too, but that one shot I will remember forever.

Best of luck to you in the draw and hope you get a wall hanger too!

Congratulations on your buck and thats exactly the experience im hoping for thank you

With your variety of bullets it would be a good idea to find the lands so you can play with seating depth . If going by book you may end up with those shorter/lighter bullets having to jump a long ways . Congrats on your new rifle .

I hear you and completely agree. Glad all this got me to open the Sierra manual up. Mainly hadn't looked at it because i havent reloaded any Sierra bullets before but obviously it has a lot of general info just on the .243. Lots of interesting stuff. Being a youtube self taught reloader THR has been an invaluable resource.

Dont know to much about that yet but I've read conversations about how to find it. So i will research that more. Ive only been loading 9mm 40 and .223 so honestly it hasnt really come up to much but you're right ineed to know that. I definitely want my hunting rnds to have maximum effect. Thank you

Good to see you are doing your research , great way to start . You can use the stripped bolt method to find the lands , won't cost you a thing and it's very easy with that rifle . A lot of this stuff is intimidating at first , just go slow and gain confidence and soon the lightbulb will stay on . A lot of it is math , being able to measure accurately is key . Good luck on your journey .
