ParticipantI would lean toward a heavier bullet with a light powder charge, say 147 grain with Titegroup, WST, Clays, etc.
There are a couple of female competitors that run a similar load.
ParticipantHead over to the Hodgdon reloading data center. I selected 357, then checked the boxes for Ramshot and Enforcer in the selections. I left the bullet selection blank.
They don’t show a 147 grain load with Enforcer but they do show a 140 and 158 grain load.
140 grain- Starting load is 14.4 grains Enforcer, 16.0 Max
I would start a little less, say 14.0 grains and work up from there.
ParticipantAre you asking about 357 Sig or 357 Magnum?
ParticipantAs long as it within SAAMI spec, why worry about it?
ParticipantHodgdon has data for Winchester 231 and a 71 grain bullet. 2.1 to 2.3 grains. Since you are using a lighter bullet, that should give a good starting point.
ParticipantI have not had a chance to try the 75 3GH but Hornady uses a .395 G1 BC for their 75 BTHP. That’s where I would start.
Remember that posted BCs are an average because velocity affects BC. A lower velocity will yield a lower BC.
Participant@augied16
Yes, that is a G1 BC. I used .169 G7 when I was shooting the 69 RMR.
ParticipantYes, a .223 Remington uses the same bullets as a 22-250 Remington.
.224 is the correct diameter for either. You just need to be careful of the twist rate. Most 22-250 barrels have a slow twist and will not stabilize the 60 grain or heavier bullets due to their length.
October 3, 2022 at 8:07 pm in reply to: (.264) 6.5 120 – 123 FMJ Why haven’t I seen any of these made by RMR? #454210ParticipantI would like to see some 105 grain 6mm’s on the menu. They are really hard to find right now from the competition.
ParticipantI am not certain of the exact BC but out to 500 yards, the 69 RMR shot pretty close to 69 SMK data that I used in Strelok. The results were hard to say how accurate the load is but with a 16″ AR, I was able to hit 100% on steel targets between 200-500 yards. The 500 yard target looked to be about 10″ X 15″, measuring with my mil reticle.

3000+ FPS velocities will damage the steel. 62 grain green tip has the thin wire inside of it to assist in penetration through steel but I’ve seen 45 grain Vmax and 55 soft points do damage as well because the steel was close, ~50 yards
Placing the steel face at a slight downward angle and setting the targets at a longer distances to allow the bullet to slow down before impact, will lengthen the life of the steel target.
ParticipantNo experience with BR-5 but I have seen others compare it to Unique. 4.5-5.5 grains of Unique is a good window to work in depending on OAL.
ParticipantBased on the description of the item on the website, 1000-1100 FPS seems to be a good window to stay in.

It sounds like you might be too long but be careful of seating depth, it can raise pressure. Not as much with a slower powder like Silhouette but should still be considered. You may need to turn down the powder charge.

I would play with OAL a little more.
