300WM ELR Shooters

As far as application will be 1500+ and exploring pushing the limits with the caliber as far as I can. I’m a hobbyist. I’ll be shooting jacketed as of right now
I'm on my 3rd heavy contour barrel on my 300wm. Currently its a lhgt 1:9.5-8.75 tw.
I have good loads for both 230AT & 225ELDM. Both a bit over 2900fps. I've so far made hits to 2289yds with it.

I am shooting an AI with 27 in M24/M40 1-10 using Berger 215's right at 2840 FPS this is the slower node but shoots right at 1/3 MOA. Have shoot out to 2000+ yards. It just get hard to see splash much passed 2000 yards. May try the 300PRC on my next new barrel
Is LHGT something that does better with monos or have you tried it with jacketed also?
I shoot a 28 inch 1-8 twist. I go as heavy as i can. I use to shoot the 225 eldms but im switching to the 230 smk. 300 win mag is awesome overall for long range. I usually get a freebore and single load get way more performance i did have the 225 eldms going 2980 but shot them comfy at 2929.
9 twist and a 30" tube is a good combination. The 200gr Sierra #2231 going 3000fps works well at distance.

26” Bartlein Sendero Contour, 9 twist with the work done by Straight Jacket Armory.
Currently running Berger 220LRHT at 2948fps with RL26. Barrel only has 60rds so it may speed up a little.
Also have a 24” X-caliber, sendero contour, 9twist pre-fit that was running the same speeds with test loads as the 26” barrel above so I sent it to be chopped to somewhere around 20” and still have decent performance.
I’ve had several other 300win mags over the years with 24-26” barrels and would run 200-215gr bullets anywhere between 2900-3000 depending on powder.

Out to a mile .345-.350 lines up very well after that I use .335 and that lines up well to about 2000 yards. Normally, I do not shoot the 300wm further than 2000 yards as it is a waste of time as hit percentages drop drastically and the same things goes with ALL cartridge combinations. The 200gr MK is a good bullet and well balanced in the 300wm. Good muzzle velocity and good precision. Accuracy is up to the shooter.........

Also check out pva 198 bullet better than the 198 flatline bc wise and cheaper
I am using an Obermeyer 30 inch 5R tight bore .298-.308 11 twist, Boots told me to use a 12 twist. I load 78.5 grains of 7828SSC and have been getting 3378fps with 190MK. I backed the load off to 78.5gr because I was having bullet failure at about 600 yards.
Look at the most recent Doppler Radar measurements from AB on WFL and PVA bullets at Clark’s Knob ELR match. We’re not favorable BC SD.
Get yourself a minimum of a 28" barrel and an 8 twist. I'm running 230atips at 3025fps in west Texas and I've taken my 300, in competition, to 1836y because that's as far as the match went. Have taken it out to 2640y on our property. Atips on dopplar did great at clark's knob and they are jacketed so they splash very well on steel compared to solids.
