.243 win load

I have a ruger m77 in .243 win and it has a 1:9 twist. I'm loading 95 grain smks .020 off the lands and getting just over a half inch 3 shot group every time. I'm using IMR 4350. Wondering if trying to get it tighter with a factory rifle would be a waste. Any other load info would be great. I also have 95 grain berger vlds and 87 grain hornady varmint.
Any help would be great thanks
Matt

Re: .243 win load

My son shoots a Weatherby Vanguard youth .243 win. 1-10 22" barrel. We ran a ladder with 95g VLD and IMR4350 from 37.5-41g. It performed great in the 38-39.5g range with 38g shooting the best at .5-.75". It is on the slow side (2650 fps) but for a 12 year old it is enjoyable to shoot and more than does the job on whitetails.

I have that same rifle if it's the Walnut stocked Ruger with a 22" blued Barrel , (but mine is rechambered to a .243 AI and accurized). That grouping is very good for a factory rifle and you's be hard pressed to find any thing better. I shoot 100g Sierra Game Kings out of mine at 3200 FPS using H414. Mine starts stringing up after 3 shots due to heat, It's very predictable.

Mine serves as a Kids hunting rifle and will do as shots are limited to about 100-200yds.

All of those bullets are great for accuracy, but expecting more accuracy is pointless.

Go for it. Thats the fun of owning a rifle, the never ending quest for the zero group.

Re: .243 win load

Matt,
I shoot a very old Musgrave 243 with a 24 inch barrel. I haven't shot it much past 200m, but at 100m a three shot group will clover leaf and at 200m all three shots will be within a 1 inch by 1 inch block. I use Somchem S365, which is similar to IMR 4350, and seat my bullets roughly the equivalent of 0.1 inches off the lands (this may well be different for your rifle). I hunt with the 105gr AMAX, 100gr Gamekings and 95gr Nosler Partitions and normally look 2600fps in the 105s and 2800 - 2900fps in the other two bullets. Try changing your primers, as I found that just changing from the normal Federal primers to the Federal Match 210 primers made a big difference in accuracy. Another trick an old hand showed me is consistent (and deeper) flash hole uniforming - that also helped grouping a lot!
Hope this helps! Good luck!
Etienne

It depends on whether you like the load or not. I've run into a few good loads that for some reason I couldn't shine to and moved on. Sometimes the rifle and I don't agree for off-hand shots, sometimes the bullet is marginal for the application, sometimes the speed is off for what I want, sometimes the accuracy is iffy at one temp. extreme or the other. If it fits every paremeter you need it to fit and you've vetted it in hot and cold weather, I see no reason not to load a couple of hundred rounds and let her buck.

Re: .243 win load

I have a Marlin X7 243 with a buckmasters 6-18 on it. Shooting Win brass, federal match primer, 35 grains of Varget, set .01 off lands, Nosler 95 grn BT. Shoots touching holes at 100 and shoots 2-1/2" at 500 yards. I think with a windless day it will do better at 500. Vertical deviation was only an inch. Bullets in a 2-1/2" line from wind variation.
