Best load information for a Remington 700 ML 50 cal.

[dpkdavis]

With barrels two months out, not going to get my smokeless up and going before season in three weeks, so I will be hunting with a Remington 700 50 cal. with a Hunter 209 breech plug and bolt nose, wanting to use Black Horn powder I just love that stuff, so could someone save me some time and what the best primer/black horn charge/bullet combo for a factory barreled Remington 700 ML 50 cal.
thanks for your time

There is no go to load. All rifles will vary but getting a good sabot fit will make things come together MUCH faster. Using BH209 i prefer a 300gr or 325gr bullet simply because it burns more efficiently with a heavier bullet. Start at 90gr and work up until accuracy drops off or you reach your recoil limit. Ive shot upto 130gr by volume and the 325gr FTX with good results in a couple 50cals and my Knight 52cal. Speed is pretty darn good too at 130gr but its overkill in most situations.

I would suggest a .458-325gr FTX and the MMP Orange if you have a standard size bore or the Harvester Black Crushrib if you have a loose bore. One of these two will usually give good results with a .458 bullet. Any 458 will actually work with these two sabots but i would avoid going over 350gr only because its not needed. Speer has some mighty fine 458s too that are "bonded" and cheap.

I use the 300 gr. 458 bullets with the black cr. rib harvester sabot. You may have to knurl the bullet if it is too loose.
If you have the ,452 bullets, I use the harvester smooth black with the 300 gr. xtp's and the sst's, and knurl the bullets up a few thousands. The mmp 24's are similar to the harvesters which is a little loose and the mmp 12's are really tight. I would use 90-100 gr of blackhorn with these loads. 110 and 120 gr loads shoot good but the recoil starts to get unpleasant.
I usually use the regular cci 209 primer in these bolt kits as they seam to work best for me.

both of mine do 66 gr by weight pushing a 250 xtp. I've shot the 300 rem 458 in a crushed rib and they shoot very well, I just don't care for recoil.

I like how easy sabotless bullets are, I like the power belt bullets and how easy they are to load but in my research on the web and here guys don't have a lot of good to say about them, you talk here in using the black horn powder one needs to use heavier bullets 300gr plus, what do you guy think about the Horandy FPB 300 and 350gr bullets ??

[GMB54-120]

You don't have to use a 300gr bullet with Blackhorn209 but it does work very well and most of the lighter 458s are 300gr. Lots of guys like the FPBs but they can be hard to load in some bores. There are plenty of .452 bullets too and many sabots to adjust for barrel fit. Knurling does really help too if you cant get just the right fit with by changing sabots.

I have probably shot more rounds through a factory Rem 700 ML than I can shake a stick at.

Here are some loads that have performed above and beyond for me in the past.

100 Gr Pyrodex 250 Gr XTP .452 MMP short Black Sabot.

90 Gr 777 300 Gr Rem Core Loke MMP Short Black Sabot.

100 Gr BH209 300 .458 GR 4500 Hornady Interbond with Harvester Black Crush ribbed

By far the most accurate load ever recorded with my stock 700 ML was with 100 GR Pyrodex FFG 375GR Buffalo Bullet SSB's with factory supplied Sabots. I recorded a .60 group once with that load and it would routinely shoot under 1MOA all day long with that load.

Generally speaking the heavier bullets with milder doses seem to do better if you are looking for bench performance. If you are looking for better drops and higher velocities then your groups are going to open up a little bit.

Ive shot up to 130 Gr of BH209 by Volume without any signs of pressure if that helps you figure out where you need to be. Best accuracy was at 100 GR though.
