Myself, my brother, and my dad all hunted for about a dozen years from my Jr high days until I graduated college with a box of 100g Hornady btsp interlocks that I loaded over imr 4831. We took a lot of mule deer over the years with those in our 6mms. I can't recall ever losing a deer. I was poor and cheap back then and just stuck with what worked. I reloaded and the family mooched off me.
Around 2004 or so I noticed Hornady started changing their bullets from lot to lot and moving the interlock and changing jacket thickness. I lost a little faith in my do everything interlocks. Around then I found SPS and got some really good deals on nosler portion 2 nds. They were about the same price as interlocks so I went to partitions for an all around hunting bullet.
The first year I switched I watched my little brother stone a nice buck from about 375 yards with my little model 7 6mm and a 100g partition. It dropped instantly and never moved. Now he requests those.
I just loaded some 85g partitions for a new 700 youth rifle I dropped in an mdt lss with a magpul adjustable stock for my 10 year Olds back up gun. I loaded some lighter h4895 and 8208xbr loads that should only clock around 3000. I'll go see which load it likes hopefully in the morning. I also did some 90g accubonds. I still have a bunch of those 2nd partitions so I'll let the kids burn them up. I shoot 108 eldxs in my 6s these days. At least the ones twisted for them.
Bb Similar story, but we used the 100 grain Partitions and 95 BTs a lot when we started. The 95 BT is about my favorite deer bullet going mostly, besides, like where you mentioned, the 108 ELD works.

Won't find a hell of alot wrong with 95 gr partitions either fact of the matter I rate them better than the 100's...mb

I'm new to reloading 243 so looking on opinions. Gun is new 243 weatherby vangaurd ll (1-10 twist and 24 inch barrel)and I have shot some factory ammo out of it just see how it would do. Shot really good. Will be using on whitetails. Suggest anything you want but i either have or can get what i list. Bullet <SNIP> 100 gr interlocks + Powder H4350 <SNIP> Opinions? IMO, in a modern bolt action rifle like a Vanguard, this is an E-Z decision. Use the 100gr Hornady Spire Point Interlock and H4350 with standard LR primers (mag primers not needed). Start a few grains below and work up to 41-42 grains of H4350.
Pursuit may be, it seems to me, perfect without possession.

I’ve had good accuracy with the 90 grain GameChanger over RL16. 44.5 grains gave me ~3125 fps.
Don't speculate when you don't know, and don't second guess when you do.

I'm kind of in the same boat here boys. Ruger American 243. 22", 1:9. Want to use the 100gr Partition. Have loads made up with H4831sc: 41, 41.5, 42, 42.5, 43. Haven't shot them yet. Oal is 2.652 vs Noslers 2.680. 2.652 is .020 off the lands. 2.680 would be jammed. Hodgdon data online today is 39-42. Older / other manuals are ALL over the place Lee 39-42 Hodgdon 25th 44-46 Hornady 11th 42-45.5 Nosler 40-44 Then I come across this: http://www.outdoorsmenforum.ca/showthread.php?t=31367(Post 11 specifically) Any thoughts here? Folks there pretty adamant that 4831 lends itself to pressure spikes. Even invoking Barsness... (By the way I've got plenty h4350 on hand also...)

Three 243's and a 243AI.......with 90 and 95g NBT's and 100g NPt's H4831 has generally given the best combo of accuracy and velocity. One of those 243's and the 243AI does like RL26 also and runs 75-100fps faster.

Very nice. Any velocity data on those loads? Just what the book suggested. Since shots here tend to be under 100 yards, way under usually, I don’t worry about it much (at all). I do like tidy clusters, but don’t obsess over those either. Good bullets with decent accuracy are what I want. With the MV in the 2900 to 3000 fps MV, these loads will work on ANY whitetail, blacktail or any other kind of deer at 300 yds and beyond, as long as the shooter can put the bullet in the vitals...a hundred grainer, has also taken down more than their share of Elk also..

Well, shot the h4831sc loads...
22" barrel, 1:9 twist, 100gr partition, RP brass
41gr 2698avg 45es 3/4" group
41.5 2737avg 71es 1/2"
42 2752avg 72es 2 3/4"
42.5 2782avg 52es 5/8"
43 2790avg 97es (yikes) 2 1/4"
Primers looked perfect and bolt lift was easy all the way.
I like the 1/2 & 5/8 groups, but I want better than 50es and about 2900fps avg. Also, I see the velocity plateau at 42.5-43 and will stay super aware of the jump to 43.5. I believe h4831 can get me there, sooooo...
Am thinking of going 43.5, 44, 44.5 and seeing how I end up in ES and group. Also not crazy about the near 100es on the last. Load is not nearly compressed, powder audibly shakes in the case.
The only question I have is on pressure and max. The old max was as high as 46 in previous manuals. Now, most hover in the 42-45 range. Hodgdon lists to 42. Nosler lists to 44.
If none of the 3 additional work, then it's off to h4350 I think.

Thanks for all the replies so far. So I got my dies in and decided to give h4350 a try with 90 gr gamechangers. Win brass and fed210. Iv got a few starter rounds to check velocities but I'm have a hard time deciding my COL. I left my bullets way out to seat later. This is my first time to load seirra anything so I dont have that manual. Anyone got a manual with 243 90 gr gamechangers? If so what is recommended COL?

4100, 1537, & 7295 are all listed at 2.700 ...
I believe your bullet is the 4100.
37-42.3gr of h4350 is what they list.

I've probably experimented more while reloading for the 243 than all other cartridges combined. Of course, it was the first cartridge I reloaded for over 40 years ago. I am currently reloading for 4 of them, of which 3 are Remington 700's and the other a Model Seven. My go-to powders are W760 for bullets weighing 58-90 grains, and IMR4350 for the 95 and 100 grain bullets. I have found those two powders perform overall better than anything else I've tried.
A lot of my experimenting has been with a Remington 700 Youth rifle, with a 20 inch barrel. It's the one my grandkids use, and they've taken a number of deer with it. I loaded it down a bit at first, as their shots were limited to 100 yards or less, but lately I've cranked it up to max loads, as they have gotten older and more experienced. 42.0 grains of IMR4350 is listed as max with a 100 grain Hornady Interlock, and it will shoot half inch groups at a 100 yards, and is the load it'll be shooting this year. Last year's load was a 95 grain SST using 40.5 grains of R16, and it also shot very well, but I'm out of R16.
I've also had pretty good luck using IMR4064 and H4350 in the 243, shooting the heavier bullets. The key to success is trying as many different components as one can, although in today's world of high prices and shortages, it can be challenging.

I tried the Gamechangers in two of my 243's, using several different powders, and just could not get them to shoot like I wanted. My best groups were with W760 powder, and then H4350. I'll check later and see what COAL I used.

42.0 grains of IMR4350 is listed as max with a 100 grain Hornady Interlock Old School still gets it done.

I’ve had good accuracy with the 90 grain GameChanger over RL16. 44.5 grains gave me ~3125 fps. that would be my first choice of the three. I used the Interlocks . They penetrate great but I wanted something that opened up a little easier. Normal distances for me are inside 200 so I load light and get good results.

To add to above
R-p brass, 100gr npt, h4831sc, 2.220 to ogive
43.5gr 2785avg 14es 3/4"
44gr 2812avg 52es 1.75"
44.5 2836 bolt just starting to get firm, so only fired one shot.
Looks like 43.5 is where I'll go .2 either way and see if I have some tolerance either direction.
Next will be 43.3, 43.5, 43.7. All above were 4 shot groups. Will probably drop to 3 shot groups here with weighed brass.
Also going to try 39, 39.5, & 40 of h4350 and see if I can pick up some velocity in the 22" barrel. I've got some 100gr npt pulls with cannelure I'll use for this. Stocks are getting low!! I ordered a box I found online and it's the older flip top, black/white/gold and sure enough it's a slightly different bullet profile - so that's a bummer.

Well today didn't go as planned - one of those frustrating days at the range...
All of the groups were bad (comparatively). I couldn't even shoot the 43.5 that was great yesterday very good today. So either it was me, or something in my process was no good. Same seat depth, same lee FCD, precise powder charges, same sizing die, same cleaning regimen, same weighing brass.
R-P brass, 100gr npt, h4831sc, 2.220 to ogive
43.3 2798avg 52es 1.125"
43.5 2818avg 57es 2.125"
43.7 2802avg 42es 1.75"
Next, I tried the H4350 loads
H4350, R-P brass, 2.220 to ogive, 100gr npt
39 2768avg 24es 1"
39.5 2802avg 28es 1.5"
40 2848avg 49es 1.25"
If there's a common theme at all - it's that anytime I break 2800 I lose accuracy (the 40gr h4350 load was alright, but I'm shooting for a sub 1" group). Each of the absolute best groups were in the 2730-2785 range. Weirdly enough - the 43.5 in H4831sc that went 2785 @ 3/4" yesterday went 2818 @ 2.125" today.
Days like today make me feel like I'm just wasting components.
