300RUM Loads

From what I have gathered here, the 200AB are the bullet of chioce for the 300RUM. Have gone back thru several pages of post(about30) and have not found what I an looking for, Which is Load data for the 200AB. Most have stated that best accuracy is between 3150&3200fps.

Please list your load data: Powder, starting point to max. and were you hit 3150-3200. H-1000,RL25,& Retumbo seem to be the most used and only data from them will be fine.
Both guns we will be working loads up for will be 26'' Rem. One sendero and one CDL.

Re: 300RUM Loads

I use 103gr of A8700 for the 200 gr Accubond and get 3200+ fps 26" tube this is a very hot load in my rifle and the brass doesn't last many times start lower and work up please...This is a most accurate load but should be approached with care...Having said this no two barrels react the same your rifle may not stand this load or it may
tolerate a much hotter load but I would still suggest caution when working up any load... [img]/ubbthreads/images/graemlins/wink.gif[/img]

Re: 300RUM Loads

I used 92g of H1000 for 3100fps and great groups. I also used 95g Retumbo for 3225fps and once again great groups. I could go 94g H1000 and get 3200fps, accuracy was still good, but not as good as at 92g. I haven't tried any RL-25. These loads were shot in factory Rem's with 26" tubes, Rem cases, and Fed 215 primers.

Rem case, 92gr RL25, Fed 215M, 200AB, OAL to as long as your magazine on your mod 700 will allow. 3150-3170 fps @ 15 ft. itty bitty 3 shot groups at 100 yd. YMMV work up from well below.

Re: 300RUM Loads

Come on guys, I know there is more 300RUM info out there.
Please include starting powder weights and don't really need max, but would like to know where you hit 3150-3200fps.

Also is there a chart online with this info.

Re: 300RUM Loads

From a recent post:

I'd agree with the 'more powder' crowd. I've heard of a few folks that have gone back to high quality scales after using digitals for awhile. To each his own...

Here's what I've found out of the same rifle with some accurizing done to it, but minus the brake.

Retumbo did not do well for me with the 200AB's. Might just be the batch I got, but it seemed like it was quick to see pressure signs. I think I was around 92g and was surprised to see the pressure signs I was seeing. Maybe 3025fps. I was so dissapointed in the pressure signs vs. speed I was getting, I started looking to other combinations.

I did develop a very good load with Retumbo and the 180AB. With the Wyatt's box, I could seat them on the lands and with 96.3g Retubo, I was doing about 3285fps comfortably at about .4 MOA off the bench. I seemed to me that at least the batch of Retumbo I had was better suited to 180's in my rifle.

RL-25 with the 200g A-frame did OK for me. 94.4g at just about 3100fps.

Now I'm working up a load with Hodgdon's US869 and 200AB .010 off the lands--gotta like that Wyatt's box. I'm getting over 3200fps with 109.5g and seeing less pressure signs than I did with Retumbo at 92g. Turned off the high spots on the necks and just neck sizing so far. Off the bench at 100yds I've been in the .3s. This is far better accuracy that I had either with Retumbo or RL-25 and the 200AB.

Again, with the 180 and Retumbo, I did quite quickly find a fine load. But it seems almost like a waste to put a 180 down a 300RUM, so...

Re: 300RUM Loads

I'm shooting the 220gr SMK with outstanding accuracy, and performance on deer size game. I dont know what your targets are going to be, but for up to deer size animals I dont feel you can go wrong with the 220 pill for long range.
