When I get to shoot the 30" barrel I'll post here.
I know what you mean about the Dakota. That is why I built my 30/375 S.I. and I love it! Same capacity as the Dakota.......rich

Re: RL-33 Load Data

I can't help but think that 75 gr in a 7mm RM case is going to be plum full. I bet the ES is going to be fairly low for the belted mags.

Re: RL-33 Load Data

I tried RL-33 in a 7 rem mag:

24" Rem barrel, moly coated 162 A-max seated .010" into rifling.

Original load: 72 gr of Retumbo 2975 fps

starting load 76 gr vel 2837
worked up to 79 gr for vel of 3000 for very small gain over Retumbo
80 grs showed a hint of bolt lift resistance and a small shiny spot on case head.

I used a bullet seating comparator and noticed that even with the use of a drop tube the powder was filling the case. 79 gr and up caused the OAL to lengthen over .010", enough so the bullet wouldn't fit into magazine.

I can see why Alliant only mentioned a load for the 175 gr bullet.

Report on the 7mm/375 Ruger: 29.5" fluted 6 groove Lilja SS 1 in 9 twist barrel. A friend fired 400 rounds through it as a 7 STW and sold it to me cheap.

180 Berger target hybrid .015" from rifling. Fed 215 match primer. RL-33

83 shot the best velocity 3210 average at 58 degrees
84 3265 groups opened up
85 3320 too hot

Shot rifle at Tucson Rifle Club's javelina and Rams to verify comeups. Rifle was very accurate at 500m despite the 15 mph crosswinds. Very pleased with results.

Will be using Bore coat in this barrel. Will wait to fall to shoot it again.

Re: RL-33 Load Data

Does anybody have some wisdom they could send my way in regards to possible loads with rl 33 for 208 grain hornady a max out of a 300 Dakota? or 250 grain otm berger out of 338 RUM? Any thoughts on if this powder would be useful in a 240 Weatherby with 105 berger? How about for 6mm AI with 105 hornady bthp?
