mick miller Posted November 3, 2014 Report Share Posted November 3, 2014 Just a thought, bearing in mind that I'm not going to be target shooting at great distances with my 243, mostly foxing, stalking and a bit of fun target work out to 300 yards, does the actual case type make a massive difference to accuracy and grouping? I now have a load that works for me, and currently I'm using federal cases but I have hundreds of Hornady and Remington once fired brass that I was hoping to use as well (using the sqme manufacturer at the same time, not having a random mix at any time in my magazine or range box). Now I know if you're after ultimate accuracy on the range then consistency in everything is the key, but for the type of shooting I'm doing am I going to have to load develop everytime I change case?

pestcontrol1 Posted November 3, 2014 Report Share Posted November 3, 2014 but for the type of shooting I'm doing am I going to have to load develop everytime I change case? One word answer NO Mine are all mixed brass and they shoot the same whether its a crow at 100-200 yrds or a fox at 400 yrds the case don"t make any difference really Quote Link to comment Share on other sites More sharing options...
mick miller Posted November 3, 2014 Author Report Share Posted November 3, 2014 Well, I know it makes a difference as far as competition or target shooting goes as each case manufacturer will have slightly different wall thicknesses and case internal dimensions, which would in turn create variations in pressure, but, I'm inclined to agree with you. My rifle is a sporting 243, 1in 12 twist with a lighter weight hunting barrel, it's never going be used on the range other than for a bit of practice at range or load dev, so I don't think minor increases in pressure up or down are going to have a great effect on accuracy, especially at sub 200 yard ranges. Thanks for your input! Quote Link to comment Share on other sites More sharing options...
magman Posted November 3, 2014 Report Share Posted November 3, 2014 I only load for the 223 at the moment but use all the same cases that way i no it's my fault if i miss you may be surprised how much a difference it can make Quote Link to comment Share on other sites More sharing options...
sixhills 69 Posted November 3, 2014 Report Share Posted November 3, 2014 I use Norma cases mostly but have quite a few winchester cases I agree that they each have different wall thickness and the like but I have not noticed any changes shooting out to 300 meters. I have a friend that strives to get each case perfect and he has thrown a load of money at it all and I still don't see much change in his shooting.

mick miller Posted November 3, 2014 Author Report Share Posted November 3, 2014 Well, you have the same rifle as me so the results are likely to be quite similar. If I get the budget I guess I could put a few different types over a chrono and see if there are any noticeable variations in terms of velocity.

mick miller Posted November 3, 2014 Author Report Share Posted November 3, 2014 I wasn't going to mix them, but rather use one type until exhausted and then switch to the next type, until my stock of once fired is exhausted. Then, likely, I'll just stick to one type, probably lapua. Quote Link to comment Share on other sites More sharing options...
mick miller Posted November 3, 2014 Author Report Share Posted November 3, 2014 Do you weigh the water in grams, measure in ml or weigh in grains? What is an acceptable deviation in volume? Quote Link to comment Share on other sites More sharing options...
malkiserow Posted November 3, 2014 Report Share Posted November 3, 2014 Fill them with water to measure the volume. I wouldn't mix them up but if you must.......... How do you measure the slight differences in the different volumes? Quote Link to comment Share on other sites More sharing options...
al4x Posted November 4, 2014 Report Share Posted November 4, 2014 Personally I would bite the bullet so to speak and buy a box of lapua and then crack on. Seems expensive at the time but you use them like I do and odds are they will last you years and you have no queries and 100 cases pretty much ready to go Quote Link to comment Share on other sites More sharing options...
nicholiath Posted November 4, 2014 Report Share Posted November 4, 2014 I have 4 different types of .243 brass and when i was develiping a load trying to settle on one brand of brass to find for that load i found a variance of about 4 grains of powder. I guess that could make some serious pressure issues in mixed brass loads. One load that was max powder charge in hornady brass shot the best. 2 of the other brass brands could not take this load without powder spilling over the neck! This was only taken to book mmax load! Not above it. Quote Link to comment Share on other sites More sharing options...
mick miller Posted November 4, 2014 Author Report Share Posted November 4, 2014 Wow, okay. Quite a difference of opinion on this one then! Quote Link to comment Share on other sites More sharing options...
spandit Posted November 4, 2014 Report Share Posted November 4, 2014 My home loads have been more consistent that factory ammunition so frankly, I wouldn't worry as long as you're not going for the maximum load each time. I'm perfectly capable of missing with any ammunition! Quote Link to comment Share on other sites More sharing options...
mick miller Posted November 4, 2014 Author Report Share Posted November 4, 2014 No, not at maximum. Actually just under minimum with n150. But too much space can be just as bad as too much powder so I'm led to believe. Quote Link to comment Share on other sites More sharing options...

I think I am on 43 grains with Norma brass Quote Link to comment Share on other sites More sharing options...
nicholiath Posted November 4, 2014 Report Share Posted November 4, 2014 Mick which types off brass have you got? I use hornady and geco at present and have some mixed makes. Tell me what youve got and i will send any i have of the same. Quote Link to comment Share on other sites More sharing options...
mick miller Posted November 4, 2014 Author Report Share Posted November 4, 2014 (edited) I use at the moment federal, but I have maybe 150 Hornady, and around 120 Remington. My load is 39.5gn of viht n150, cci primer behind a 70gn nosler ballistic tip. C. O. L of 2.680". Nice offer nico!

sixhills 69 Posted November 4, 2014 Report Share Posted November 4, 2014 My load is 38.4gn N140 with a 70gn Sierra Blitzking col 2.666" i use Norma Brass but I use the same load with 70gn matchkings but use Winchester brass and get the same results on paper I only use matchkings for practicing of sticks and on paper.

I don't have any remington brass and i use my hornady brass for my 58 gn vmax loads. Soz mate 😣 Quote Link to comment Share on other sites More sharing options...
mick miller Posted November 5, 2014 Author Report Share Posted November 5, 2014 Nay bother, there are loads of hornady and remington in the drawer. I'll just use those, as I'm already just under minimum load I can only imagine that I may need to add a little more powder if the volume of the cases used increases, certainly I cannot really use less.

Cambsman Posted November 5, 2014 Report Share Posted November 5, 2014 Fill them with water to measure the volume. I wouldn't mix them up but if you must.......... And don't forget to record the temperature. Obviously. Remember that volume is inversely proportionate to temperature. P1V1/T1=P2V2/T2. Just saying. Can't be too careful.

nicholiath Posted November 9, 2014 Report Share Posted November 9, 2014 scratch that mick! i was thinking of my hornet brass. My . 243 brass Hornady has largest capacity next to geco. Quote Link to comment Share on other sites More sharing options...
