"Apparently Winchester and Remington must have gotten a number of requests for a .30-30 varmint round back in the early 1920's and offered .30 W.C.F. Super Speed (Winchester) and .30-30 Hi Speed Mushroom (REM-UMC) cartridges. Both were loaded with 110 gr. hollow pointed bullets at a cataloged 2,720 f.p.s. which was "sizzling" fast for that time.
Even though the bullet tip was smaller than normal it was safe to use them in a tubular magazine since the cartridges line up with the bullet off center to the cartridge in the front.
As replication of the that early loading I use the 110 gr. Sierra with enough 4198 to push it to the early ballistics. (Original cartridges used IMR 25 1/2 the forerunner to 4198 ). H335 works well too. Accuracy has been very good and the 300M steel javelina doesn't stand a chance........"
I have not found a reference for what the actual purpose of the 110 gr. h.p. loading was for. Based on the bullet weight, the hollow point, and the velocity (2,720 f.p.s.) one could assume it was intended for varmints and such.
Here's a Winchester box from the same era as the REM-UMC box. Note that there is no bullet weight shown but the "Super Speed" moniker indicated a 110 gr. bullet back then.
There were a number of other Winchester "Super Speed" cartridges introduced in that era. All with lighter for the caliber hollow point bullets..... 25-20, .32-20, .25-35, etc.

The Winchester box clearly shows an 'HP' for will take thst as meaning hollow point.
The Remington UMC box just says 'mushroom bullet'. Was it truly a hollow point?
Or was it a jacketed soft point?
casastahle,
Rem-Umc used the term "Mushroom" to indicate hollow point. It had a full jacket to the hollow point like the two cartridges in the photo. The left cartridge was pre 1930 and had a tin plated jacket. Winchester dropped the tin plating on all of their bullets after 1930 (right hand cartridge).

casastahle,
Thank you for the kind words. I have been very interested in cartridge history and thankfully have acquired some knowledge that I am happy to share.
Here's the business end of a box of Rem-Umc .30-30 110 gr. "Mushroom" bullets.

I have a friend whose son killed two nice eight point bucks last year using the 110 grain expanding load. Both deer dropped right there.
He has shared his load recipe with me and I have loaded some and find accuracy quite good.
I see no reason not to expect this load to work well on deer since other calibers use a much smaller bullet.
