If you have so much powder that it has to be compressed, you're way over charged. TAC is very dense.

My rl-15 charge with 250s is north of anything I've seen listed on this thread. My pressures are likely high but the primers look ok and and the bolt lifts easy. I'm clocking just over 2600 and the accuracy is exceptional. I might consider reducing it a bit because 2600 with a 250 may be pushing it a bit too hard even if everything else seems to look ok.

I'm running over 2500 with 250's and 58 gr of Re 15, with utterly no sign of pressure, so I'm not so far behind you. I suspect if I were chronographing at 8000 ft instead of sea level I might be even closer yet grin. This load puts three 250 gr RN's under an inch consistently...at 200 yards.

Mostly it hits stuff and they die pretty quicklike... smile.

I took my custom BRNO out Sunday and tried 57g of RL 15 with 250G Speer Hot Core. Was at 3.33 COAL. The Norma Brass was 2.92 at 72.4 gH2O after firing. WLR primer. Chrony averaged 2600 fps.

Calculated pressure 61,881fps. at that velocity with Quickload, well crimped and sitting .01 from the lands.

No / NADA NONE signs of stress on the rifle or brass, smooth extraction. Nice clean and sharp recoil with a satisfying "crackboom".

I would say 57g is very MAX Hot Load with the new RL 15 coming from Sweden.

Any thoughts on that theory?

Could be lot to lot variation seen that before in RL 15. Have not bought any new RL 15 for aprox. 5 years. The Whelen does well with most mid range powders.


My 22" 35 Whelen with 250 Gr Speer shot the best around 2500 FPS with RL 15.

My Std load for my Rem 7600 35 Whelen Pump rifle is 56 Gr of IMR 4320 with usually the Speer 250 Gr bullet. about 2525 FPS, Or around 56 gr older RL 15 with same bullet.

I started out with 56 grains of 4320 under a 250 grain bullet in my 35 Whelen and it shot so well I didn't see a need to change. I have tried RL15 and it worked fine, similar accuracy and velocity, but didn't notice any advantage over the 4320. That's not a slight on RL15, I just have a lot of 4320 so don't see a need to change.

Fortunately I found this thread a few years ago when I started reloading for my Whelens. All three of my reloading manuals show a max of 54 grns of Re15 for 250 grn bullets, but I've been using 57 with 250 Interlocks with no signs of excessive pressure, and have made it a point to shoot in hot weather a few times. Chrono readings range from about 2420-2450 fps.

Interesting,I tried RL-15 in my Whelen and was getting 2200+. The max I found was 53.0 grs and that is what I worked up to. May try RL-15 with a 220 gr Speer just for fun.

I'm using 55.0 grs of Var-Get,250 gr Speer,CCI 200 and from a 22" barrel,the velocity is just over 2400 fps.

I have been shooting 58 grs. of RL-15 in my Jack Haugh rifle as its my most accurate load, but it will shoot 60 grs. and that is its max load..I had another and 58 was its absolute max, proceed with caution.

When I shot in competition an old guy named Rudy Wadekamp
told me about Varget.
He shot a 198 with iron sights at 1000 yds.
If it's good enough for Rudy it's good enough for me.

I have to say that 35 Whelen was my favorite rifle for about 18-19 years it still is except I gave it to my son I started out with Reloader 12 but without me knowing they quit making it so I moved to 15 had all intentions of using 250 bullets but after shooting a while noticed that only way to get good groups was to single load the magazine recoil and oversized magazine in my Rem 700 keep smashing the exposed lead so I tried Nosler 225 accubonds and have not looked back. The thing I noticed was that I could load them long and not have interference with rifleing and she loves them that way. Reloader 15 is my go to powder.
The Whelen is a great cartridge that Remington almost killed with factory loads that were lake luster and barely beating 35 Rem.

I run 57.o gr RL-15 with 250 NPT's in a strong bolt action.

Most book data stops at 55.o Prolly cuz there are Amish machine guns out there. wink

I typically use 57.0 grains of RL-15 with 250s as a starting point and go up from there. I've had several Whelen rifles and never had one that wouldn't safely use 59.0 grains of RL-15. My current Whelen reaches a bit over 2500 fps with 250s. Years ago Alliant listed 59.0 grains as a max load, I don't know why that's changed as I was getting similar velocity then too. I suppose anything that's had as tumultuous of a history as the Whelen has in wildcat form, it creates a tendency towards such downloaded data.

I've been using 58.5 gr RL15 with 250 gr bullets for over 20 years now. Any spitzer I have tried(Nosler PT, Speer HotCor, Barnes X, Hornady IL, Swift A-frame) has worked best at .050 inch off the lands for some strange reason and shoot .8 to 1 MOA for 3 at one hundred yards. Hornady round nose soft points and Woodleigh RN Weldcores I just seat to the cannelure and Lee Factory crimp. These shoot 1- 1.125 MOA. These loads have chronographed from 2520 to 2550fps in R-P brass and Remington 9 1/2 or Federal 210 primers. These results have held true both in an original 700 Classic and in a 700 CDL.

I also like the RL-15 in my 35 Whelen. Hornady RN 250 gr. I get about 2600 fps. My standard hunting load. Primers will flatten out when I get closer to 2640-2650 so I back down my loads. Great moose thumper load and rifle. Just wish it wasn't a 1-16 twist brl. But it works with the 250 grs.

I use 250 NorthFork's and Varget or H4895. Nosler online data. Works better than R15 in my rifle.
Go to 2500-2550 and stop.

I ran 60 grains of 15 with 250 PTs at 2600. Haven't worn a primer pocket out ever nor have I ever had a pressure sign.

I've since gone to 225's in the Whelen and use 250's in my Newton.
