.300 RUM loads for factory sendero?

[dmproske]

I have a .300 RUM Sendero SF-II. Factory barrel with a break & 3lb trigger. Am looking for your favorite loads with factory Remington barrels.

I will probably be using 180 and 200 grain accubonds as they seem to be favorites here. Also please advise your case trim length and cartridge overall length.

I searched for some loads on here, some of the links don't work any more. Found some loads listed but need some suggestions on seating depth.

My 300rum sendero likes the 200AB over 92.5 gr RL25. OAL is all my mag. box will allow. This round will shoot about 1 1/4'' groups at 300yrds on a good day.
And before ya ask about 3'' at 300 on a BAD DAY. This round sighted in at 300 is about 7'' low at 400 and 18-20'' low at 500.

I'd use some JB in the bore before you shoot it.Seems like all the remingtons I shoot like it I get a used bore brush put some jb on a patch and give it about 50 strokes and then put another patch on the brush and give it another 50 and one more with 50.After that the groups tighten and the gun cleans easy.Good Luck Ron

JB Bore paste. It's a super fine lapping compound, and it works great!

Thank you Wallowa...I thought it was a shot at Remmies, and fireball thought he should use JB Weld!! lol

dmproske...I have not tried these loads so start lower!
The fellow I got my 300 from was using 100 gr Retumo over 180 gr AB's.
He also had good luck with 80 of IMR 4350 under the same boolit. Again, I HAVE NOT used these loads...
I am getting some of those powders, as well as RL-25, to try with Wildcat 210's.
Have also put in an order of 180 and 190 gr Hairfield type boolits from Richard, for hunting our CWD'd whitetails and mulies.
Lot's of tags this year-extended season and Sunday hunting as well!!

Good Luck,
LeRoy

We shoot 95gr of Retumbo under a 200gr Accubond in Rem brass lite by a Fed 215MM primer. We get right at 3100fps and all groups between .300 and .750 in three different Rem 700's. One is a Sendero, it shoots the best of course..gun)

Thanks for all the replies guys.

WSlayman, What was your seating depth on this load?

No not JB weld LOL!JB bore paste I use it in new guns it speeds up the brake in and polishes the bore and it doesn't copper up as bad and cleans easier.It also cleans copper out of the bore well.And I like remingtons,I use JB on every factory gun.
