hey guys
I finally got all the gear to reload this 9.3 T3 with some 250grainers but theres a little hiccup.

the woodleighs have a suggested impact velocity for all individual projectiles, the 250 RN is rated 2000-2400 and the PPSN is 2000-2700 fps.

going off some Data I have some of these Muzzle velocitys for min charges are 2320*fps or there abouts whilst the max loads are closer to 2500*fps....
I realise impact velocity is not muzzle velocity however it kind of important

I think I am going to load the RN 250gr first up and since looking over numbers and numbers I thought I would Ask you CGNrs youre thoughts.......

I'm a little confused with all the numbers and its taking over the practical thinking in me,

(I know its not useless as is) However a Minimum Load of powder say around 56gr behind a 250gr RN an say it produces 2300fps , Do you think this is still very usefull for Me in shooting Sambar deer(elk sized) out to 250m max - (We have dicussed the fact RN an PPSN don't differentiate too much over distance regarding MV is equal........)

Do you think its Wise to 'load down' the PPSN and load up the RNSN so they impact the same POI at 100m? (would there be a need to load different charges???) if both come out similar pace, they aught to hit the same place.. right

By loading down I mean just not running the PPSN as fast as I could in high end charge, an using a mid charge weight.

Do you think that I'm going to Miss the 100-200FPS for what I intend to do?



discuss please..

now I write this its like the 308 V 3006 comparrisions, 200fps all that splits them and both do it well hmmmm

FYI- I didn't come up with the idea to load MID to have both suit the 100m POI theory until I wrote this Thread.

sounds bloody good on paper :D
 
your talking impact velocity verses muzzle velocity , unless your at point blank range , these are NOT the same things .

you can easily use bullets rated at 2000fps impact velocity , even in a rifle that is throwing those same bullets out the end of the barrel at 2700 fps ....

and you can do this because the second the bullets leave the barrel they are slowing down , and by the time they reach your target , they should be very close to their rated impact velocity .

really the only thing to be aware of is if you get up close and personal with something , it will create a a lot of meat damage as the bullet blow up on the hide ........ the upside is , it is a 9.3mm and a heavy bullet , so there is a lot of bullet mass that still wants to force its way through .


myself i find a load that works , and that is the load i use 99% of the time , i sight the scope in to that load , and i practice with it at various distances until it becomes a known entity .

pick a load your comfortable with , and use it .

myself i wouldn't leave 200 fps on the table , i'll take it and figure out how to safely add another 100 fps
 
copy that an yeah I know I'm on two different pages RE the MV an IV but ones kind of going to be below REC IV reasonably sooner than the other, and I too am thinking that it will matter mostly on those under 100m shots in the thick Bush the Australian forests are, although I have used 225gr RN in the 35 Whelen for the exact same use and it proved to be fine at proberly the same speed..


This particular gun , I am shying away from TBH, loaded right up I think the recoil is too much for me to be placing shots but as we/I tend to slap it like a shotgun while stalking , I can handle it in that scenario.... which gets me thinking I'm slappin a RN up close and not really placing shots at 300m with a PP I think I have answered my own Q here........

I also think once I have a go with these 250s that I will load 232s up in the higher end of charge weights for that flatter traj for 300m. (cos I want to do youtube video at all ranges on game with 232gr 9.3) priority but the Dude sent me heaps of 250s to use!

thanks again,
 
Have you considered 286gr Nosler Partition's? I currently have these (0.482 ballistic coefficient) loaded in my 9.3 (x74R) at about 2400 fps muzzle speed. Should perform well, good downrange energy retention and should expand well over a broad impact speed range.

I'm considering the 320gr Woodleigh RN SN instead which should out-penetrate the 286gr NP's. I could likely get these going 2300+ fps in my No.1.
 
I've heard of folks on here with mv of 2700fps with 250 grain in 9.3x62 with a hot load

Are you sure your not thinking of velocity for 286 grain?

I picked up 250 grain accubonds for my 9.3x62 steyr and will be reloading this spring or summer after I fire form some brass, I don't remember barrel length off hand (around 20") but I'm hoping for at least 2550-2600fps with the NAB's.

What powder do you plan to use btw?
 
Let's face it...even if the bullet didn't expand at all you would still be making a nice sized hole through the plumbing. Certainly big enough to kill the animal. Now, that's a worst case scenario. Best case is full expansion. Even if you start the RN at 2300 you'll still get good expansion at 200m. Perhaps not as much as you could if you started it at 2600, but again, how much do you need to get the job done? We're not talking about a mono metal bullet that needs to be driven hard to expand so you should be fine with your daughter's practice loads.

oh I used a rough number of 2500 but thought more along lines of 2600 but yes some here do push envelopes along a bit quicker toward 2700!

going off the Data I had infront of me ther 9.3x62 stuff varied a bit, but I'm sure around 60gr of 2208 would yield plenty of Velocity in that +2500 range!

Ill be using AR2208 aka Varget for My loads!

some data shows for a 232 HYDRO Woodleigh its velocity is 2455 with a Compressed charge of 60gr............ (I'm assuming due to length of projectile/less powder space)
I know the 250RN and 232PP are the same length close enough.

so if this data shows 250gr with 61gr charge and 2520fps I have to be able to put 61gr of powder in for more than 2520 with a 20gr lighter projectile! the 232s will be another project shortly- 250s for now.


With your short barrel, you will be in the high hot end of loading for sure, but I assume your powders better suited for pace!

Slammer, No- I have a bit of a Woodleigh hook up/ sponsorship thing goin on , so I continue to use Woodleigh, but exclusively now unless there is no projectiles in the right size :D

not really looking to out penetrate or fully penetrate things, remember we are talking Big Deer not Big Elephants :D


I just get a bit worked up by all these numbers Especially figures you post yourself... an you begin thinking well hey this is guna bounce of em if it Can go that quick. then you imagine a flatter than expected velocity an all that ####....... then you go back an look at possibly 2700FPS and you're looking to loadd at 2400 FPS............ Well #### me, to me that's Chalk and Cheese

So Subtle, Big Ugly Mumma .


however, Thanks for the maken sense.
 
If it was me (and I had enough bullets to test with) I would load 3 of each in 0.5 gr increments and load from Start to Max, and then choose which ever one grouped best. Making sure to let the barrel cool between tests.

I find in hunting situations it is often important to me that I have a lot of confidence that the bullet will go where I aim it.

I sure would not worry about the bullet being too fast. They slow down a ton in the first 100 yards.
 
Right, your Woodleigh deal and you prefer 250gr -

RN SN: 0.281 bc, 1800 - 2200 fps recommended impact speed.

PP SN: 0.381 bc, 1900 - 2600 fps...

The Woodleigh manual lists 2490 - 2560 fps maximum depending on the powder used. Assume you load both with good accuracy to near maximum speeds. RN SN could over-expand/penetrate poorly at close range, or the PP SN could under-expand at long range.

Need to be cognizant of the range at which you take the shot for proper performance using either bullet because tracking wounded game is never fun. Seems the RN SN might be a better choice if you choose to load these at lower muzzle speeds.

The 320gr RN SN should be good for general purpose. It should shoot accurately at 2200 to 2300 fps muzzle speed from my No.1 (to be confirmed). The ballistic coefficient isn't too dismal so it should still have enough speed to expand out to 200 meters. At close range it should expand quite well and has enough weight for good penetration.

I ended up loading 58gr VARGET to 250gr RNSN , so approx. 2400fps.
in time will load an test PPSN side by side

Not a FAN of it though, fairly snappy!

Thought so. They're a tad on the light side, aren't they? That would explain the exuberance.

haha- Yep, its fairly light for what it is, however I rekon its heavier than the old T3 308 I had... perhaps a larger diameter barrel contour but id have thought the larger hole would of equalled that out.. it does wear a Limbsaver also.
there is steel rings on it and perhaps the scope isn't very light but definatly Spoiled by the Kimber when it comes to other rifles-
but Bum, I Safed the ol Ruger hawkeye 35 whelen in favour of a Lighter gun in just as potent Calibre but in the end what I have is something that is only in the hundreds of grams lighter..

Id say there is a fair change that by next Summer I will be full an proper ready to Sell it, in favour of a T3 3006 id say.
 
I had a tikka hunter in 9.3x62 and felt it was pretty comfy, I was just shooting fairly lightly loaded PPU (Prvi partizan) factory 286 ammo and had a bit of a heavier scope (30mm tube, 2.5-10x50mm nikon prostaff 7) and it wasn't bad, I actually really liked that rifle, you may want to try upgrading the recoil pad which is a common swap for the hockey puck rubber they put on the back of the tikka's from the factory.

If you have a T3 lite it may make a bit of a difference as the hunter as the heavier barrel. I believe Jeff270 on here is shooting the thing now.

I found myself a left handed steyr model M fullstock, my "unicorn" and didn't feel I needed two 9.3's so it went to someone else.
