Model 12 LRP in 243 Win.

[Dennis]

The problem I have with it is that it is marketed as a long range precision rifle and I would like to shoot the bullets designed for that, atleast as heavy as possible. This was my attempt at upgrading to a better setup for 600 yard shooting and farther when I could access a place to do so. I would hate to have to put a new barrel on a brand new gun so I could shoot 95gr and heavier bullets.

I understand. I have shot 55's, 70's, 95's, 100's, and 107's out of mine. the 55 & 70's held the tightest groups. The 107's weren't bad, but were no were near the others. Might try 105 Bergers or some JLK's. I have a few 105 JLK's (maybe a few Bergers) if you would like to try a few of these.

The 55's, 70's, 95's, & 100's were Federal Factory loads. The 107 smk's were hand loaded, probably the reason they did better than the 95 & 100's.

Just giving you my experience with my 243. I loved the rifle, I couldn't ask for anything better when shooting the 70 grain Federal NBT's. Pretty deadly on small game.

Picked up LRP in 243 in 2012 and found accuracy node right away with H4350 using Hornady 105gr AMAX. Fed 210 primers and Federal brass. First and best node found with 36gr H4350, Jump 40-60 thousandths. Similar loads and results with Berger 105 and 107 SMK, each with slight variances in Jump. Muzzle FPS around 2850. Many have noted another accuracy node with higher powder charges but its nice to save barrel life being less hot. Has been reliable with no pressure signs, accurate and great brass reuse for over 5 years now.

Now, anyone made progress with loads for new Hornady 103gr ELD-X in .243 Win?

Always research reloading books from powder and bullet makers when reloading and stay between min and max charges which in my case was almost right in middle range.
Good luck, use reloading best practices and be safe!

May 2,2021 Update: After Lots of Load testing for last couple years, I found an operational Load for My Savage LRP(.243) with Hornady ELD-X Bullet. Using H4350 at 38.0grs seated 10 Thousandths off rifling, I found a load tested 100-300 yards, Sub-MOA. Unfortunately this load had to be loaded single shot as OAL was to long for magazine. BUT today I worked up a Load with a COAL of 2.795 that would fit and operate properly from my DB Magazine.
The LOAD uses 37.9gr H4350 with a Jump of ~95 Thousandths off the rifling. This yielded 5 shot group Sub-Moa at 5/8th Inch Center to Center. MFPS = ~2880.
Temp 66 Degrees, Altitude = 5,280ft. ( Boulder Rifle Club ) and Yes, the twist on my Savage LRP(.243) is 1:9.25. No tumbling with perfect holes out to 300yards.

So for all that said the Savage LRP(.243) could not stabilize Hornady 103gr ELD-x with out 1:8 twist. It can be done just like it can for Berger105, HornadyAmax105, HonadyMatch105 and SMK107(Each shot from this rifle in Bench Rest Competitions).
This Barrel has over 2000+ Shots already and with the New H103gr ELD-X Load that fits the DB Magazine - My LRP can continue as a High Accuracy Hunting Rifle and retire from use in Bench Rest Comps. More load tests for future from 37.5gr H4350 - 37.9 to check if OCW load.
