Looking to load some reduced recoil rounds in 6.5CM that the kids might be able to handle for hunting (whitetail). I have some 100gr Nosler Partitions and I've read IMR4198, Varget, Trailboss and h4895 are good options for powder. My question is does anyone have any first hand experience, or advice, with the 100gr partition reduced load?

I think Trailboss is better for plinker loads, as velocities aren't that high. I'd look at somewhere around 29-30gr of 4198 as being a good place to be in the 6.5CM with 100's. I've loaded 31gr of H4198 with a 110TTSX and a 120gr version in a 7mm-08 to good effect. Seafire wrote often of using 30gr of IMR4198 with 85-100gr bullets for fun loads in a 260. The internal capacity on the 6.5CM is practically the same.
Now with even more aplomb

How reduced do you want the load to be? Do you have a chronograph?
I'm a fan of IMR4198 and IMR3031 for reduced loads in several cartridges from 243 to 35 Whelen. What I've loaded up for my wife and daughter in 6.5 CM uses a starting charge of R-15 and 120 gr bullets. It's pretty mild, but it still may be more than what you are after. If you want a significantly reduced load, powders faster burning (such as 4198 and 3031) than the medium-burn powders (like Varget or H4895) may be your best bet, but you could jump in with H4895 at a 60% charge, which is what Hodgdon recommends for reduced loads, or around 24 grains for a 100 grain bullet in the 6.5 CM. You can "work up" from the 60% charge to find a particular velocity you are after, or maybe a specific accuracy standard, or you can stay at the roughly 24 grain 60% charge.

H-4895 will work best. I’ve used it a lot for grandkids.

Thanks guys. I just read the Hodgdon info on reduced loads they have on their site. I think I'll start with the 4895 at 60% like mentioned above and see what kind of velocities I'm getting and go from there. Thanks for the help!

I load 24gr of H4895 with a 100gr BT for 2000fps and 32gr of H4895 with a 100gr PT for 2600fps in the .260 Rem I set up for my daughters. Should be pretty much the same in a 6.5 CM.

If you have some 4198... load some of those also with a charge of 30 grains... and compare the retort , or how loud the H 4895 reduced load is... then compare the group size with 4198 and a reduced 60% load of H 4895.... also note how much blow back you have on the case of the reduced H 4895 load, vs lack of it on the 4198 load.... and at those speeds, compare the performance of a 100 grain Ballistic Tip vs the partition... the 100 grain Sierra HP is also a good alternative...

I’ve loaded 60% loads of H4895 for a 270. Raised it up 5% each year for oldest grandson. He never knew the difference.

Thanks, I'll give that a shot with the 4198. I put a few rounds down range of 60% and 65% H4895 and definitely noticed the amount of blow back on the case. They did however group nicely. I'm shooting suppressed so the report wasn't really an issue. I forgot the chronograph the other day so I'm not sure what speeds I was getting with those, but I already put together some more of the same loads that i was going to test out this week. I'll put together some rounds with the 4198 and see how they compare. Thanks!

I've never seen where the reduced H 4895 load was as accurate or more accurate than the 4198 loads.... and not being blow back, it is sealing the chamber, hence not the blow back...
Hodgdon only pushes the H 4895, because it was given to them by ADI.... when the Austrailian Armed Forces wanted to know if there was one powder they could use for everything....that is the reason the 60% H 4895 loads...
Hodgdon sells ADI's 4198 as it does the IMR formula it was copied to dupllicate...
If you want to duplicate their 60% rule, with out the blowback, and also obtain more accuracy, then substitute IMR 4895....
I've worked with all of this stuff quite a bit...so I am speaking from hands on experience......at the reload bench and on the range and in the field...

I’m speaking with a little experience too....
123 SST 32.0 H4896 GM210M 2.780” 2475 FPS Tikka compact (20” barrel)
No 4198 load compared to this load and I tried a bunch of powder charges and seating depths. And actually, the 4198 was louder and had more blowback. The case necks look almost perfect with the 4895 loads. That can’t be said the for the 4198 loads I tried. Accuracy with this load is phenomenal in that rifle. Much better than the 4198 loads I tried.
I know the OP is talking about 100 grain bullets, but the 123 was designed for the Grendel and I figured it would be perfect for the Creed at Grendel velocities.
I enjoy handguns and I really like shotguns,...but I love rifles!

Funny how two guys can have the exact opposite results....
and I am also sure both will still stand by what they posted...
