Known Loads for .243 90 grain bullets? IMR4350 and short on time

[CoolArrowMarksman]

Looking for help for quick load development just to get me in the game for the upcoming Texas state silhouette match. Limited on time for load development so I thought I'd ask the hivemind. Crossposted on steelchickens as well.

OEM 1980's Remington 700 in .243 1-10 twist
I have IMR 4350 and Berger 90 grain Boat Tail Target - Tangent Ogive
Open to ordering other bullets of course, but powder takes a little longer to deliver

I have some Barnes 105gr Match Burners I'm going to give a shot for Rams, but keeping expectations low because I know 1-10 is not likely to be able to stabilize them well enough.
I just read from a guy on the net that he had success with them in a 1-10 twist, can't find the post or remember the forum though.

Any and all help appreciated!

I'm just worrying about Chickens, Pigs, and Turkeys with this request for help. I have a good amount of time on smallbore but just now really jumping in to High Power. Going to shoot this barrel and caliber up until I either get to a point of pulling my hair out because of rung rams or until the barrel burns out on me

Any and all help appreciated! I will be able to put in the time and effort on real load development later in the year after Service Rifle Nationals in July.

I've got a factory Remington as well, and am not sure of the twist but it is probably similar to yours. The 105 Amax stabilizes at 100 yards pretty well but a Hornady 105 BTHP and Nosler 105 RDF were terrible.

On edit: My former Remington 243 ADL shot the 95 SMK really well but I have not been able to find those in a while.

I've tried the Speer 100 BTSP and am getting just over 1" groups on my first outing. Next up is changing the powder to RL17 and seating them a little longer.

Hodgdon shows 38.5 Starting and 42.0 Max for IMR 4350 with the Speer 100 BTSP.

My 6BR with a mild load and a 105 will take down rams as long as I hit them in the upper half.

Thanks!
I've heard that the length of the 105 Barnes MB and the 105 Amax contributed to them being able to stabilize even in a 1-10 twist
The Amax looks to be discontinued.

Barnes load data for the 105 shows loading:
IMR 4350 a minimum of 38.9 up to a max of 43.2
I know with this one I'll need to do a real work up to find an accurate load since this load data is based on a 1-9 twist on their website.

On the hunt for 95 SMK's!

Hmmm...I have some 105MB and should give them a try.

I feel like as long As i work up the load responsibly the worst that can happen is they suck haha

105 Amax with H-4350 will not stabilize in my 10-twist Tikka

IMR4350 works very well in my remington 243 using 95 grain ballistic tips, it shoots the best with loads at or near the max.
I'd try it with those Berger 90 grain bullets, they are accurate.

I have shot and reloaded the 243 Win for over 50 years and in my experience, IMR 4350 is an excellent choice for bullet weights 85 grains and over.

However, I have never shot Berger bullets so I cannot comment on that combo.

I have shot a lot of Nosler, Hornaday, and Sierra bullets out of the 243 with twist rates ranging from 9 to 10. All shot exceptionally well with 90 to 100 grain bullets and IMR 4350.

Another excellent powder is IMR 4064 with all bullet weights.

Don't leave out h4350 either

Open to other bullets too for the 90's/95's
I'll give the stuff I have a go and stop overthinking it
